Question about Maytag Neptune FAV6800AW Top Load Washer

1 Answer

Maytag Neptune FAV6800AWW UC Error, TDS & probable clutch failure

My washer began to take UC and dc errors to the console board during a wash cycle. I first verified the tub displacement sensor which read 2.7 VDC at all times regardless of the position of the sensor. I ran the TDS diagnostic test in service mode which began with it telling me it was UC. Obviously the sensor is bad, so i replaced with a 1.5 VDC battery. (Not sure if the output from this sensor was a square wave though, which could be causing me issues, also one of my questions?) But regardless the diagnostic tests now begins by telling me its "in". So I ran all the other tests in service mode, the washer passed ALL tests with the exception of the quick service cycle, which gave a dc error. I also tried to wash clothes with a normal cycle and it fails once in the wash cycle with a UC and then after pressing play it fails again in the spin cycle after it begins spinning and pumps all the water out. I cannot get passed this point in the cycle. I can, however, then quit the normal cycle and run a spin cycle only and it will complete (odd to me). I read various posts on the site which indicated this may be a clutch issue. So, I removed the clutch and relubed, everything tested out ok, both prior to the relube and after, i.e. spring in tact, no slipping. But now when I reinstalll the clutch and reseat as required the pulley will not spin in one direction. It will spin the tub but when the motor or hand tries to turn the pulley in the opposite direction the belt slips and starts to screech. My clutch has the green top clutch roller bearings along with the white bottom clutch roller bearings with the coupler between them. Please help me with any explanations....

    Thanks for the help and quick reply. You are correct about having the clutch not seated correctly, I turned the washer on its back and was able to reassemble correctly and now the pulley works in both directions with no slip. The tumblers rotate maybe half turn prior to the tub spinning. When I had the clutch disassembled I tried spinning the coupler in both the upper and lower clutch bearings and there was no slip. The battery was attached between Tub sensor + and Tub sensor ground pins 11 and 12 on P3 at the control board. I coiled a couple of wires making a battery compartment similar to all machines where the battery goes and then inserted the other side of the two wires into the top of P3, mind you only a temporary solution. Prior to the consistent failures there was no major bouncing just periodic UC failures (maybe 1 per month) and now no full cycle finishes. Do you know of any way to troubleshoot the sensor without purchasing a new one yet?

  • homeworker14 Apr 23, 2010

    There is slight corrosion on the sensor board. My measurements are all taken at p3 as you have shown. The sensor consistently gives 2.53-2.55 V as I move it over its full range.

  • homeworker14 Apr 24, 2010

    The supply voltage is 12.5-12.7V both at the control board and the sensor when plugged in. Thanks for the offer for the sensor but already purchased from appliance pros should be here Mon. I'm afraid I'm still having clutch issues... I had the clutch properly seated at least I thought but now the tumblers will rotate but the tub tries to spin then stops retumbles tries again and gives UC error. Washer never did this type of thing before. I'm not sure if the clutch is working properly, Let me explain manual operation, spinning pulley CCW winds up spring then engages tub spin CCW, spinning pulley CW unwinds spring and spins tumblers CW as viewed from top looking down. Seems like spring operation is what is causing the latest problems. Any comments?

  • homeworker14 Apr 24, 2010

    I think the new UC errors are generating from something from the clutch. The old UC errors were consistently failing at a certain point in the cycles, now everytime the tub tries to spin I can hear the spring coiling and then the tub never actually gets to spin and the UC error is displayed.My belief is that there are several things that trigger the UC error code, the TDS which I've removed, and something monitoring the torque or motor timing.

    "Did you try this test? With the continuous High 2.53-2.55 V it may be moot point.
    Tub Displacement Sensor Diagnostics check."

    I performed the tub diagnostic check with the bad sensor and it began by reading "UC" while being in the middle of the two arrows. This is when I replaced with the battery to simulate 1.5V and then the diagnostic check began by reading "in". I cannot move the tub out of range with the battery so I thought this would isolate those problems and allow me to look at the clutch.

  • homeworker14 Apr 24, 2010

    What do you think about the spring coiling? I don't remember this happening prior to me disassembling the clutch. It seemed like previously the switch between tumbling and spinning was immediate (1/2 turn maybe at most). Now it requires the spring to fully coil or uncoil before moving to the opposite direction.

  • homeworker14 Apr 24, 2010

    Sorry forgot SN = 10

  • homeworker14 Apr 24, 2010

    Let me clarify the TDS test...The service mode does begin with "00". The TDS diagnostic test begins by saying "in" now with the battery installed. With the bad sensor in, the TDS diagnostic test began with "UC" not "in" as its supposed to. I can disconnect JP4 and run the motor control test and the tub spins fine. Does the spring coil and uncoil each time switching from Tumbling to Spinning and vice versa? FYI I'm more of an electrical guy than mechanical. Since I can run the motor conrol test (i.e. entering board output test and pressing "whites") I beleive that some logic related to the signals from JP4 connection is generating the new UC errors. I refer to them as new because they are generated at a different time then before messing with the clutch. I can spin the clutch CCW and it will coast to a stop within a few turns. There doesn't seem to be much resistance when rotating. I agree with you it might be best to wait for the TDS before tearing everything else apart. I will redrop the clutch and mess with that a bit tonight. Thanks for the help, again.

  • homeworker14 Apr 27, 2010

    Update... New sensor is in and giving correct voltage and diagnostic checks. However, the washer is still failing with a UC code. The sensor is laying on the ground and set between the two arrows so this is not genereating the UC error. It fails at the same place everyt time. Once in the wash cycle at 29min and then I push play and it runs through a rinse begins to spin drains and then pump shuts off tub stops and UC generated again. I cannot get beyond this point. If I push play it reruns the rinse starts to spin in the spin cycle pumps out and fails. I don't understand why its failing at the end of the wash cycle. Any other ideas? I don't beleive the clutch to be the issue I see no slippping and have reoiled several times. Thanks in advance.

  • homeworker14 Apr 28, 2010

    Ok. I think its fixed, so far two waches and no UC errors. The control board actually looks for voltage swings from the TDS and calls the swings normal. A steady voltage will cause a UC error at certain points in the cycles. With a fluctuation in the voltage the machine thinks it is operating correctly because it expects certain swings and tub vibrations when switching from spin to tumbling and between other various cycles. Again thank you for your input.

Homeworker14,
You’re a owner/DIY’er type I enjoy working with I'm a technicial owner also not a repair person. Warning my post are long but with no BS or WAG's.

Good job troubleshooting except for the external 1.5VDC battery. I understand what you tried to do The TDS takes +12VDC into it and signals +3.0VDC to 0.0VDC for the full range of motion of the TDS and as you are aware approximately +1.5VDC for center position. So the Control Board sees analog DC swings from the TDS not a digital 1 or a 0.

Was your washer banging around during the start of a Spin Cycle of a wash Cycle or a Spin Only Cycle causing the original dC/uC unbalance errors? If not the TDS may have been bad from the get go. You will have to explain to me how you clip leaded in that 1.5VDC cell I’m curious. Keep in mind the +12.0VDC power supply on the Control board is referenced to the control board not machine Chassis ground. Here is a pic of me measuring +12.0VDC indicating that the lid latch is closed. I pick up Control Board Common from the lead on the cap I show on the board.


Maytag Neptune FAV6800AWW UC Error, TDS & prob - 46c8082.jpg
OK knowing that is this how you measured the +2.7VDC referenced to Control Board Common and Conn P3 Pin 11 the TDS Sensor input to the Control Board? Some Pics to help.


480f68f.jpg
Also Check for corrosion at the 3 pin plug of the TDS.


You are performing your measurements at Conn P3 pin 11 TDS input and Control Board Common correct?

Let me know what you find. This BS board has message limits so I will post on Clutch issue in the next comment.....Rich

    OK the Clutch

    “”I read various posts on the site which indicated this may be a clutch issue. So, I removed the clutch and relubed, everything tested out ok, both prior to the relube and after, i.e. spring in tact, no slipping. But now when I reinstalll the clutch and reseat as required the pulley will not spin in one direction.

    At this point of troubleshooting I don’t feel the tranny is locked up I feel the Clutch is not seated properly.



    Page 47 of the SM ……When reinstalling, properly seat Pulley with a 1/16-1/8" gap between the Pulley face and shaft end.



    Did you have a wash/agitate issue prior to removing the clutch pulley assembly? In wash/agitate the Motor spins the Clutch Pulley CW.



    Did you follow my post Clutch Fix for tear down, re-lube and reinstall?



    I would reseat the clutch pulley and insure fitment of the Upper One-Way Roller Clutch bearing the Spinner Shaft Coupler and the Clutch pulley. I know removing the drive belt and reinstalling is a *itch.



    Before you reinstall the Clutch Pulley Assembly take a few minutes to try the little test I show of inserting the Spinner Shaft Coupler into the White One-Way Roller Clutch bearing plate. Understanding what causes the One-Way Roller bearing to slip in the CCW Spin direction and the dC/uC errors caused by sliping One-Way Roller Clutches that don’t lock up solid will help you in troubleshooting dC/uC unbalance errors with the FAV6800A and FAV9800A machines. Most people just *hit can the $1K machine when a little effort of clutch maintenance or replacement will extend the service life.



    I’m no expert just a technical owner like you and will try to help………..Rich

    Does +12.0VDC measure correctly at Pin 3 and 4 of Conn P3? Referenced to Control Board common? I believe it is if the machine is working as you described. If so then yes I would replace the TDS. I have three that work from e-bay purchase. I would not spend $70+ for it. I would let go for $20 + shipping and I guarantee it to work. All my spares work let me know. I have a One-Way e-mail at dh1200s@yahoo.com if you have an interest ping me if you are interested. Just leave a reply here to have me check that mail box.



    But let’s make sure +12.0VDC is correct at the Pin 3 going down to the TDS…….Real good working with you a very refreshing experience working with someone who is not beating up on the machine but try’s to resolve issues . You will find the machine is very easy to troubleshoot. It takes a bad rap from owners and repair people that just don’t have a clue how to troubleshoot the machine.



    I have the schematic in PDF format if you need……..Rich

    homeworker14,


    What is the first two digits of the S/N of your machine? It will be 10 thru 17.

    “”I had the clutch properly seated at least I thought but now the tumblers will rotate but the tub tries to spin then stops retumbles tries again and gives UC error. Washer never did this type of thing before.””



    I feel you are getting false UC unbalance error code from the continuous high 2.53-2.55 V from the TDS output voltage to the Control Board TDS input Conn 3 Pin 11.



    Is the wash tub banging around to throw the UC unbalance error code? I feel you are on the hairy edge of the Control Board triggering the UC error code. So is the wash tub banging around to cause the UC error code? If not I feel it’s a false trip because of the High offset 2.53-2.55 V you are measuring at Conn 3 pin 11 and Control board common. You are making the TDS measurement referenced to Control Board Common where I show the green clip lead correct? Maybe there is another common reference point I’m not aware of. I tried Conn 3 Pin 10 and I get wacked out readings.



    Here is my write up on what causes dC and UC unbalance error codes related to slipping One-Way Roller Clutches bearing. I this point of troubleshooting I do not feel you have this issue base on you clean up/re-lube of both the upper bearing ring One-Way Roller Clutches and the Clutch Pulley One-Way Roller Clutches.



    What causes dC and uC unbalance errors in the FAV6800AW (LED display) and FAV9800AW (LCD display)





    The bulk of the issues I have come across related dC and uC unbalance errors in spin cycle are due to the clutch design in the FAV6800AW and the FAV9800AW machines. The clutch design incorporates a One-Way Roller Clutches (click on the link for additional info) for Wash and Spin cycle operation. This Roller Clutch bearing rotates freely in the Clockwise Wash-Agitate direction allowing the agitator shaft to drive the transmission which will rotate the tumblers in wash cycle.





    In Spin Cycle the Control Board signals the Motor Controller to power the Motor to rotate in the Counter Clockwise direction which is the Spin Cycle direction. When the Motor rotates the Clutch Pulley in the CCW/Spin Cycle direction the One-Way Roller Clutches lock up and drive the Spinner Shaft CCW. The Spinner Plate is now rotating CCW. The Transmission and Wash Basket are mounted to the Spinner Plate and they along with the Agitator shaft are all spinning CCW at the same RPM and the tumblers do not rotate.





    Here comes those pesky dC/uC errors.





    When the One-Way roller clutches do not lock up ROCK SOLID they allow some rotation slippage of the Spinner Shaft coupler allowing a slight amount of rotational difference between the agitator shaft and the wash basket causing the tumblers to move a bit which moves the wash load enough to cause the unbalance condition. The Wash Tub starts oscillating (banging around) and the Tub Displacement Sensor attached to the Wash Tub signals the Control Board of the Wash Tub movement. When the max Wash Tub excursions are signaled to the Control Board the Spin Cycle is shut down by the Control The Control Board will attempt several redistribution attempts of the laundry wash load. When the magic number of wash load redistribution attempts is reached the Control Board signals a dC or uC unbalance error code to the display.





    If the TDS has failed in this unbalance condition and did not signal the Control Board to shut down I feel this would happen. The machine would shut down by walking across the floor until it unplugged itself or shook itself apart. I always recommend folks to do a through the lid TDS check when troubleshooting dC/uC error code events.



    I have to break up this post this board has message limits. It's geared up for vague responses like call in a Service Repair Company....;)

    The rest of my response;

    Did you try this test? With the continuous High 2.53-2.55 V it may be moot point.

    Tub Displacement Sensor Diagnostics check.
    It is possible the Tub Displacement Sensor may have failed try this check which is in the Troubleshooting guide stored in your washer console or refer to the SM.



    a. Enter the Service Mode by pressing and holding the Enviro Plus and Spin Only keys for three seconds or the display reads “00”



    b. Press the Super Wash key display reads “in”…something like that.



    c. Press Delicates the Display will show “UC” (Unbalance Closed).



    d. Push tub to the back right corner of the machine the display should change to “UO” (Unbalance open). Release tub and the display will show “UC” (Unbalance Closed).



    e. Press Hand Wash.



    f. Pull tub to the front left corner while pushing the tub down the display should change to “UO” (Unbalance open). Release tub and the display will show “UC” (Unbalance Closed).

    “”I think the new UC errors are generating from something from the clutch. The old UC errors were consistently failing at a certain point in the cycles, now everytime the tub tries to spin I can hear the spring coiling and then the tub never actually gets to spin and the UC error is displayed.””

    You hear the Large Wrap Spring compress (normal) and you throw a UC error. My understanding is that the Torque I believe you are referring to on Conn P25 pin 6 is the digital PWM signal to the Motor Controller that signals the motor Controller to Power/Control the washer Motor Speed and Direction.

    Tach is an input pin that has the pulses from the Motor that signal Motor rotational speed for both Spin CCW direction and Wash/Agitate CW direction of motor rotation driving the Clutch Pulley.

    Well you have a TDS replacement in route I would wait for that install and see where you are.

    “”This is when I replaced with the battery to simulate 1.5V and then the diagnostic check began by reading "in".””

    I’m not sure what you are saying here. When you first enter into Diag mode you don’t read “00” you read “in”.

    I know when you enter Board Input test you read “in”

    “”My belief is that there are several things that trigger the UC error code, the TDS which I've removed, and something monitoring the torque or motor timing.””

    Not from my experience but if you confirm please let me know. If you have a fully functional machine and you remove the TDS input by removing the 3 pin plug at the TDS or the +12VDC source by removing Conn P3 Pin 3 as I show below to the TDS you will throw a continuous UC error code. May be a Repair tech that is has hands on knowledge of the FAV6800A or FAV9800A can speak to that.

    Interesting problem this is how we learn good work……Rich

    I assume there is slight resistance to rotate the wash basket CCW with one finger (checking Outer Tub Bearings rotational resistance)?



    If you spin the wash basket CCW up as fast as you can it should coast down after several rotations to a gentle stop.



    If you follw my Clutch Fix post and the Clutch Assembly looks and operates as I show I believe the clutch is OK. You can always drop out and reinspect. If you rotate the Clutch Pulley by hand it will take 3 or 4 turns to compress the spring and the wash baket should begin to rotate CCW. Difficult to see while laying on the floor. Got to leave for work will check in tonight 0100am EC.

    Good deal I saw you first post while at work could not respond and I was scratching my head. As I mentioned before I did not think there was any other monitored inputs for the Control Board to detect an unbalance condition other than the TDS input….. my comment “”Not from my experience but if you confirm please let me know. If you have a fully functional machine and you remove the TDS input by removing the 3 pin plug at the TDS or the +12VDC source by removing Conn P3 Pin 3 as I show below to the TDS you will throw a continuous UC error code.””




    So the machines processor (TDS input) is looking for normal dynamic DC swings (within the range of +3VDC and 0VDC). It seems like the Maytag design team wanted to make sure that the machine would not get into a unbalance situation where the failure of the TDS would allow the machine to shake itself apart.



    Good issue one for the book.



    Watch out for corrosion issue with the left hand lid lock producing OP,OD,and FL error codes. The bleach dispenser is hard on components i.e Left Hand Lid Lock, TDS and the Left side strut……Rich

What's the purpose of the tub displacement sensor


To detect excessive wash tub movement and shut down the wash cycle. Here is a copy of my post from a real DIY forum;

Google this Neptune TL Washer FAV6800AWW 5 post down.


Here ya go.....in this post I discuss the issue related to unbalance error codes DC and UC;

Your FAV6800A or FAV9800A is going off balance with DC or UC unbalance error codes during spin cycle and you see/hear the wash tub banging around at the start of Spin Cycle of the wash cycle or a Spin Only cycle. If this is the condition the TDS (Tub Displacement Sensor) is working as designed and signaling the Control Board properly of an unbalance wash load condition.

The Control Board receives a varying D.C . Voltage from the TDS sensor and if the out of range D.C. Voltage limit continues the Control Board will halt the Spin Cycle and try to redistribute the wash load. If you are interested I will show you how to monitor the TDS input to the Control Board with a DVM.


The Control Board then starts the Spin Cycle again. If the wash tub/basket out of balance condition continues the Control Board will attempt another redistribute of the wash load. After several attempts (4 to 5 I believe) the Control Board will shut down the Spin Cycle and send a error code DC or UC to the LED display of the FAV6800A, my machine type. And I believe a text statement to the LCD screen of the FAV9800A machine i.e. something like "Unbalance Condition" I'm not sure what the text message is.


If you need help open a post in that repair forum and I will try help you through your issue.

Maytag Neptune FAV6800AWW Washer was working fine then failed to enter spin mode and would not drain after a wash cycle. Repair tech came and said both control board and clutch was bad. What are the odds...


What error codes if any for failing in Spin Cycle?
If the Clutch One-Way Roller bearings are Slipping in spin cycle you will get tumbler movement as the wash basket begins to spin up.
If the TSD is working as designed you will get unbalance errors such as dC or uC and the machine will shut down. This tells me the Control Board is responding correctly to the Tub Displacement Sensor (TDS) signaling. Is that the failure scenario?
See this post Clutch Fix for Fail to spin issues related to a Clutch malfunction. This is a very common problem for the FAV6800A and FAV9800A machines
If you can provide additional info on you issue that would help me. Does the tub bang around as you enter spin cycle then fail with unbalance error codes?
Most service techs do not have much hands on experience with the machine. If we can get closer to the fail point and you can DIY the fix you will save big dollars.
I will guess you quote to repair is in $350 to $500 range maybe more

See my Clutch Fix post for more info related to dC and uC unbalance errors with the FAV6800A and FAV9800A TL’s and the repair action…….Rich

What does the code "UC" mean? The "U" is half as tall as the "C"


It is related with the improper balance of the machine or a problem of the sensor. You can get a full explanation about this error here:

Maytag Neptune washer has the error code of UC during the spin cycle. What is the problem?


in the Maytag Neptune FAV6800AW Top Load Washer Forum so I assume the machine type is a FAV6800A or FAV9800A correct?

Most issues are caused by a Clutch malfunction if the machine errors out with dC or UC unbalance error codes during the spin cycle. If your wash tub is banging around during a Spin Cycle and the TDS and Control board are working as designed the Control Board will shut the machine down with an unbalance error code dC or UC.

If the machine model is a FAV6800A LED console or a FAV9800A LCD console version it can be fixed with basic hand tools and some DIY effort. If you call in a repair service you are looking at $300 to $400 ballpark if they have a clue of how to troubleshoot the issue. If you DIY cost could be $0 if you have a can of WD-40 around a dab of lithium bearing grease to $75 ball park for a Clutch Pulley replacement.

See this post Clutch Fix and if you want to DIY and save/extend the service life of your 1$K machine.

Wont Finish Spinning stops and Flashed DC


If the machine type is a FAV6800A/FAV9800A see this Clutch repair post if you want to DIY. You will find links to the Service Manual and parts info if needed.

You can check out the TDS but I would go right to the Clutch repair post if the machine shuts down in with a error code dC or uC.

That means the TDS is producing analog voltage swings +3.5VDC to 0VDC to the input of the Control Board Conn_P3 pins 10 and 11. Those DC voltage swings are at the design limit of max Wash Tub movement and the Control Board shuts the Spin Cycle down……..so thebTDS is working as designed.

The machine will make several attempts to redistribute the load before error code generation failing with dC or uC error codes.

Post back if you have questions any DIY'er with basic skill sets can do the Cluch maintenance/repair.....Rich
