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.

Stops will not spin had censor replace still will not spin.


Is the wash tub banging around in Spin Cycle with a wash load then failing with a dC or UC unballance error code?

If so the TDS is working as designed. Try a Spin Only cycle with no clothes in the wash basket. If it completes then the issue is most likely a clutch malfunction of your FAV6800A or FAV9800A machine. See this post Clutch Fix

Did you replace the TDS sensor or did a repair person? If it was a repair person did they try a Wet Load Spin Cycle after the TDS replacement?

If a repair person was called and the TDS replaced what troubleshooting steps did they take to warrant changing out the TDS? I would ask if the range of montion check of the TDS was checked for properation signaling action to the Control Board in Service Mode.

My Neptune washer is showing error code dc..once it starts the spinning cycle the machine will stop.


See if my Clutch Fix post will get you started if your machine model type is a FAV6800A or FAV9800A.
Service Manual for reference. Sears Parts Direct for reference.

Your TDS is working or the machine would shake itself apart.

If you decide to DIY I will help you thru the process. If you decide to have it repaired show the Clutch Fix post to the repair tech it will help him help you back into service......Rich

Neptune Washer Spin Cycle


If your FAV6800A or FAV9800A wash tub is banging around in Spin Cycle of the Wash Cycle and your Control Board signals a dC or uC error code to the console I feel you have a Clutch malfunction. I feel the TDS is working as designed with the unblance error code shut down.
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 FAV6800AWW UC Error, TDS & probable clutch failure


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.


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.

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

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

The problem was with the component that i suspected, the motor control board. I replaced it and everything is operating as designed. Thanks for your feedback and confirmation of my thoughts.
