Question about Maytag Neptune FAV6800AW Top Load Washer

1 Answer

Maytag Neptune Top Load FAV6800AWW -- tub/motor will not spin

I have a Maytag Neptune Top Load, FAV6800AWW. The washer has stopped washing or spinning.

When I start a normal wash the washing mashing will fill up with water, but when the tub is supposed to start spinning nothing happens, and the timer just counts down. When I try to put the washing machine in a spin only cycle nothing happens and the timer counts down also.

I did the "motor control test" as specified in the service manual:

* Disconnect the power
* Open washer and disconnect the JP4 Connector from the Motor Control Board
* Reconnect Power
* Go into Service Mode (press Enviro Plus + Spin Only keys for 3 secs)
* Access Board Output test (press Delicates) -- displays shows "ot"
* Lid is locked
* Press Whites to start the Motor Control Test
* The motor starts and will rotate the tub/spinner at 50 RPM.

With JP4 connector removed -- when in Board Output test, I can fill the tub with hot or cold water, I can drain the tub, I can start the motor. But when the JP4 connector is connected the motor will not start.

When the motor test is running, if I use a Volt meter to test the voltage of the wire harness between L1 and Neutral (gray and white wires on the connector that has only three wires running into it) -- I see a 120 VAC reading.

When I disconnect the power and reconnect the JP4 switch and try to run a normal Spin Only cycle the motor and tub/spinner will NOT spin.

Is this indicative of the Motor Control Board being faulty?

Do I need to replace the wiring harness between the Motor Control Board and the Motor?

Is this the Main Control Board that is faulty?

Any help in this matter will be appreciated, please.

Thank you,

Cameron

    I have done some more "investigation" into my problem. When I set a washing cycle (e.g. normal, whites, etc) from the top control panel, or if I select the spin only cycle, when I click the start button I can hear a "click" coming from somewhere at the top [main] control board, then followed shortly by another click from somewhere down below around the base area, which I assume is coming from the motor control board.



    Does this mean that the problem is with either the main control board or motor control board? Or is it more likely to be a problem with the motor or motor clutch assembly?



    Thank you,

    Well ? it has been some time since I have been able to get back to the washing machine and perform more troubleshooting as you suggested. Here is what I have found:

    First I ordered a new Washer Motor Control Board #25001079, and installed the new Washer Control Board ? this did NOT resolve the problem.

    Then I performed the following troubleshooting/diagnostics and took the following measurements:

    With JP4 DISCONNECTED:
    Measured the resistance of the motor windings of the large connector:
    white--black: 5.8 Ohm
    black--brown: 5.8 Ohm
    white--brown: 5.9 Ohm
    Measured the resistance of tachometer (between the gray-gray wires) of the large connector: 180.2 Ohm

    JP4 connector CONNECTED:
    Voltage between white & gray wires on JP4 connector:
    No cycle selected: 0 V (or actually ~ 240 mV)
    Spin Cycle selected: 120 V
    Measured the resistance of the motor windings of the large connector:
    white--black: 5.8 Ohm
    black--brown: 5.8 Ohm
    white--brown: 5.9 Ohm
    Measured the resistance of tachometer (between the gray-gray wires) of the large connector: 179.6 Ohm

    After replacing the Washer Motor Control Board, when I select and start the spin cycle, the tub will attempt to start spinning and rotate for a fraction of a second or 1/3 ~ 1/2 of a complete turn...

    After leaving the washing machine in the spine cycle mode (and nothing happens) I now see a code "Lr" (LR) on the LCD panel.

    Any further help would be appreciated, please.

    Thank you,
    Cameron

    I ordered a new Main Control Board. After replacing the main control board the issue was resolved...! So it appears that it was the Main Control Board after all :-)



    Thank you to everyone for your help, advice, and recommendations! I appreciated all your help.

Hey Cameron,
I saw you post today on another forum and did not have time to put my thoughts down before work. I agree not a clutch issue I had to :), you would be so lucky. I own the machine and can’t offer any more troubleshooting then what you have done, good job of that. Unfortunately the FAV6800AW/FAV9800AW SM doesn’t have a whole lot of support for troubleshooting beyond what you have done for this issue. I found more info from the MAH3000 manual on the technical operation of the motor controller (slightly different controller). Both machines use the same troubleshooting paths. Remove JP4 which is;
P1 Motor Control common
P2 Torque (to Motor Controller) see page 1-11 MAH3000
P3 Motor Control Tach (to control board input)
My WAG is replace the Motor Controller 1st, then Control board 2nd and a possible tach issue related to the motor. That’s enough WAGing,…. but with troubleshooting not a complete WAG :).
Take a look at pages 2-5 thru 2-11, I keyed in on page 2-11 in the MAH3000, it may give you some additional insight, I know we are dealing with different machine designs but I think the designs are close regarding motor controller, the motor and what the Control Board is doing and looking for with input from the Motor Controller. I wish the FAV6800AW/FAV9800AW SM gave this kind of detail for troubleshooting. There is a nice little troubleshooting table on 2-11.
I keyed in on this note;

The motor control monitors the signals and communicates this information to the machine control (control board). The purpose of this signal is to tell the motor when to energize each winding in the motor and to tell the machine control the actual motor speed.

Then this note;
Note: If the machine control board does not receive an input signal from the motor control/tachometer circuit (JP4 connector), the motor speed will rapidly accelerate for 5 seconds then shut down. The machine control will sense a "locked rotor" condition and the motor will stop. If the motor control does not receive an input signal from the motor, the motor will "****" for 5 seconds then shut down.

I don’t believe you have that condition. I have worked with a forum member who had an issue with the motor controller related to an Lr error, locked rotor error and replacing the Motor Controller fixed the issue. Form here I vote for an issue with the Motor Controller. Not having known good parts makes this a difficult job.
The control board is under warranty for 5 yrs from DOP, the Control Board is 2 yrs. Ebay is a good source 25001079

I would push Maytag CSV for both. I got them to send me a Control Board after discussing my troubleshooting and that I had a neighbor (me) that was a repair tech who would install. I also had to send them copy of my warranty not sure why they beeded that my machine was on file with them.
In your console you will find a Troubleshooting guide if you haven’t pulled it out already. It has the schematic for the machine which I find handy. If you want a soft PDF copy of the schematic I can e-mail you. Just ping me at dh1200s@yahoo.com. I use that for one-way contact, just respond back on this post if you ping me, I don’t check the account for month’s at a time.
With my limited knowledge I will try to help you. Good luck. Rich

    Cameron,

    I know you are being asked for measurements on the Motor resistance windings and the Tach output pins. I have a known good motor and here are my DVM ohm meter readings. I have the motor on my work bench so the readings come from the motor socket but they all confirm the FAV6800AW/FVA9800AW maintenance limit range.

    Tach output pins 4&5 on the motor socket = 183 Ohms



    3 phase windings of the motor socket =



    1 & 2 = 6.2 Ohms

    2 & 3 = 6.2 Ohms

    1 & 3 = 6.2 Ohms



    This SM is poor for support regarding this issue, the MAH3000 SM is much better.



    I feel to really troubleshooting without known good components for swap out, Motor Controller, Control Board and Motor will be very difficult. If you get the nominal resistance readings on the motor then I would say the motor is good.



    For me to troubleshoot without swapping out components of a known good Motor Controller and Control Board I would need to know what the digital output signal from the Control Board (Torque) to the input to the Motor Control Board would look like on an O-Scope. I would have to see good 3 phase AC voltage readings to the motor windings and observe motor tach output to the Motor Control board and then to the input of the Control Board. I believe only us die hard DIY’ers who have access to a dual trace O-scope would go to that extreme in troubleshooting.



    So where would I go from here as an owner. I would check/reseat all plug and socket connections going to the Control Board and on the Control Board except the ribbon cable form the console to the Control Board, that ribbon cable is fragile and is not causing this issue.



    I still lean toward a Motor Control board issue (WAG) and that is the only major part I don’t have in my machine spares, I’m watching ebay If you were near the 19344 area I would bring over to you a spare Control Board (I got from Maytag) and a my known good motor.



    “”When I set a washing cycle (e.g. normal, whites, etc) from the top control panel, or if I select the spin only cycle, when I click the start button I can hear a "click" coming from somewhere at the top [main] control board, then followed shortly by another click from somewhere down below around the base area, which I assume is coming from the motor control board.”” The relay click you hear from the Console I believe is related to the Motor Control relay switching 120VAC down to the Motor Controller. I haven’t pulled out my Motor Controller out so I can’t speak to a possible relay on the Motor Control Board, I don’t believe there is.



    Watch the motor as you press the start button Spin Only cycle. Do you see the motor move slightly CCW? Not sure where the “click” sound comes from the area near the motor/motor control board. If the motor glitches CCW it could be from the large wrap spring in the Clutch Pulley.



    This not a clutch issue we have to get the motor to turn CCW for Spin Cycle and CW of Agitate/Wash cycle.

    Hey Cameron ,

    As I mentioned in my first post without having known good parts this would be a difficult problem to troubleshoot for me as an owner and I feel a repair person would be in the same boat. You have good resistance readings off the motor windings and the tach pins on the motor per the FAV6800AW Service Manual maintenance limits. You do what I call a static test “”Motor Control Board Output Test”” where the motor controller places 120VAC on a set of motor windings and the test passes. My understanding is the Motor Controller takes single phase 120VAC and converts that to 3 phase 120VAC to control the direction and speed of the motor. The Motor spins CCW for spin cycle and CW for wash/agitate cycle. That control signal comes from the Control Board to the Motor Controller. I mentioned the Motor Controller would have been my first choice next the Control Board. See if you can get Maytag to send you one. As I mentioned the FAV6800AW/FAV9800AW manual leaves a lot to be desired for troubleshooting support.





    I don’t think your new LR error code is coming from any binding in the clutch or transmission. With power off see if you can rotate the clutch pulley CCW by hand several times. Have someone observe the wash basket it should rotate CCW. Then Rotate the Clutch Pulley CW and the tumblers should rotate. You can also lift the lid of the washer and you should be able to rotate the wash basket CCW with one finger and have very low rotation resistance. The wash basket will not rotate CW. That would give us some feel if there is high rotational resistance that could be caused by the One-Way Roller Clutch bearing, transmission or binding within the Spinner Assembly. If you haven’t had a clutch issue in the past trust me you will down the road.







    If you have severe binding I would think you might take some belt screech. I know of one user that reported that with the One-Way Roller Clutch bearing rusted/frozen up.



    Good Luck Rich

    Hey Cameron,

    How are you making out? I feel the next component check is to swap out your console Control Board. I have some recent E-Bay purchased Control Boards that I have tested good in my FAV6800AAW. If you want to give it a try I will send you a Known Good Control Board. Paying retail price for parts to swap out can get very costly. Sorry to hear the Motor Control Board did not get you back in service. The only way I see to troubleshoot without swapping out a known good Motor Control Board would be to have access to a O-Scope and verify PWM (Torque) Motor Control Signaling from CONN P-25 on the Control Board to JP-4 (Torque) input to the Motor Control Board and then verifying 3 phase 120VAC output to the Motor.



    I admire your desire to continue on. If you want to continue on ping me at dh1200s@yahoo.com and we will exchange some info so I can send you a Known Good Control Board no cost. That would be my next step in troubleshooting this issue. I’m a not a repair person I’m an owner/electronics tech with some basic hands on experience as you with this machine. The yahoo e-mail is for one-way mail and I do not check it unless prompted. Ping me on this board if you drop me msg to that mail box and I will respond back to you.



    Maytag Neptune Motor, Belt and Wiring Harness based on the parts I just picked up from this seller this is an excellent buy. I have a spare motor.



    As I mentioned all my spare parts except for the clutch are picked up used. Good buy above if you are interested. I picked up a Motor Controller and drain pump both work and are in excellent condition from this seller. I’m waiting on the Console with Control Board and left lid lock. Both purchases were for $9.99 :) shipping $15 something ):

    Hey Cameron,

    Glad it worked out for you…. EXCELLENT JOB! So many of these machines get put out to the curb on bulk trash day. You are now an official FAV6800AW GURU. Hope to see you back here trying to help other owners. As you get into this machine and acquire some hands on it’s actually a very easy machine to troubleshoot (with known good spares). It gets a bad rap from folks that don’t have the hands on.



    Three basic known good parts are needed to troubleshoot most issues. Top to bottom as you have seen they are Control Board, Motor Controller, & Motor, motor has a 10 year warranty as the tranny. You can get the dc/UC unbalance errors cleared up usually with a clutch pulley, roller clutches clean up and re-lube. That is the only part I would buy new and only spend $60. The left hand lid lock is a PITA with corrosion issues and most times that can be cleaned up or re-solder corroded lead off the magnetic reed relay. Other minor issues are stuck pressure switch, TDS issue. If you don’t have surge protection on the washer 120VAC source I would add that. Future problems dc/UC errors 10 times out of 10 related to the roller clutches in the clutch pulley. Left Hand lid lock errors ie. OP,OD FL, LO errors. You may want to drop out the clutch and re-lube the roller clutche before the dc/UC errors start see this post.



    These links for the Left Hand Lid Lock issues corrosion issues is a real problem with the that assembly.

I Have A Neptune Washer Model FAV6800AWW Have error code of LR Lock rotor? what is bad? control board ot motor or both?


Motor for the most part is bullet proof has a 10 yr warranty

I would start with front panel removal and see if you can rotate the Clutch Pulley CW the Wash/agitate direction and CCW the Spin direction. Make sure nothing is seized.

It could be an issue with the Control Board or the Motor Controller. I have working spares for all and that makes troubleshooting easier.

If you decide to troubleshoot further and try a Control Board swap (in the console) or a Motor Controller swap I would buy parts from a supplier that will allow you to return the part for refund with no questions asked.
Google this ""Neptune TL Washer FAV6800AWW"" a forum where I help owners of the FAV6800A and FAV9800A machines.
