Neptune fav 9800 aww Machine can not spin because the unbalance circuit is always open or out of range

is the drain pump ok .ie if the water does not get out in the proper time the mach will think it is still full and will not speed up

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.
The forum is free and my time is free I just don

I can point you to what the problem is most of the times. See if this post will get you started if you want to save your $1K machine.

I feel you have a Clutch malfunction a very common problem with this the FAV6800A and FAV9800A TL's. Your TDS is working as designed or the machine would shake itself apart.

I have stopped supporting this forum to many issue with posting support pics and directions at this site. This site it is not a in my opinion a true DIY site for owners.
If you need additional help Google "washer repair forum" and choose any of the Appliance Repair forums that you hit. Post your model number and I will help you out. If you don't have the FAV6800A/FAV9800A Service Manual I can help you with that at a true DIY Appliance Repair Forum.........Rich

You can get the manual on the link below.

Good Luck please rate 4 thumbs up and please leave a testimonial

The LL error code is not documented very well.

Can you tell me what point of the Wash Cycle the Cycle Status LED is in when you error out with the LL error code?

I believe it will be in the Spin Cycle of the wash cycle.

You could try a Quick Spin test and see if the wash basket will spin up to 850 RPM with no laundry in the Wash Basket. See Page 14 of the Service Manual and see if the Wash Basket will spin up to 850 RPM.

You could also check the TDS for proper range of motion using the SM or this typed out process.
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).

If you fail this test it would be time to remove the machine front cover check if the TDS sensor has fallen of its mounting position between the Tub and the washer frame.

If it's a FAV6800A or FAV9800A you could have Outer Tub bearing issues brought on by a Tub Seal leak.

Have you had any unbalance error codes such as dC or uC in the past?

Open the washer lid and spin the wash basket as fast as you can in the CCW direction the Spin cycle direction do you hear metal against metal sounds? Does the wash bsket coast down after several revolutions to a slow stop?

If it's Outer Tub bearings this is a big job but can be done by anyone who is handy and some direction. What are the first two digits of your machine serial number found here;



The range is 10 thru 17......

Hello zacas6,

dC/uC unbalance errors are caused almost all the time by a Clutch malfunction. Take a look this post and see if you want to DIY the repair. I will help you through the process.

I would also check the Tub Displacement Sensor. This a thru the lid check and you get a feel of how to enter Service Mode.

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.

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 have some additional info if you decide to remove the Clutch in the machine if you are going to DIY.

I had the same issue with FAV9800AWW, the Quick Spin Test showed "Machine cannot spin because the unbalance circuit is always open or out of range." Removed the Tub Displacement Sensor, disconnected the wire harness to the sensor, and found corrosion between the contacts, especially on the 12V DC pin. When I cleaned it with isopropyl alcohol and soft brush, discovered that the trace had corroded away, and so the board was not receiving the 12V DC input. Also had checked on the pins of the blue/white (signal) and pink (gnd), and was always negligible millivolt reading. The part number is Whirlpool 12002194. Ordered it from Appliance Parts Pros after reading various reviews. I found it cheaper other places, but those places got too many poor reviews for my taste.

If it’s a FAV6800AW or FAV8900AW and you want to DIY a fix take a look at this post and see if you or someone you know has some very basic mechanical skills and can do a clutch replacement or roller clutch bearing re-lube. The dc/UC unbalance errors are a very common failure issue with the FAV6800AW/FAV9800AW clutch.

I have put together a step by step process to perform a clutch replacement process, this repair will get your $1000 machine back in service with a $50 dollar clutch replacement. Worse case you can give the repair person some facts and maybe control cost and speed to repair. I believe you will find you will pay $300 - $400 to have it repaired.

If you pay more than $50 dollars for the clutch you are throwing money away. Clothes Washer Clutch - 25001169

You can try this test just to rule out the TDS as the failure point almost all the time dc/UC unbalance errors are related to clutch issues with this machine model.

Press Hand Wash.

Pull tub to the front left corner while pushing the tub down the display should change to “UO” (Unbalance open). If you get these results your Tub Displacement sensor should be OK and I believe it’s not the component failure producing dc/UC errors in spin cycle. I would remove the clutch for inspection and re-lube. There is a more technical troubleshooting method to check Tub Displacement Sensor in the Troubleshooting guide and Service manual.

We can turn on the drain pump in Service Mode to pump out excess water, let me know if you need help with that. The link I have in this post will send you to the Service Manual on this site in PDF format .
I believe a lot of folks toss this $1K machine when a $50 dollar clutch replacement or an even cheaper a Oneway roller clutch bearing clean up (if the bearings are rust free) will get the machine back in service.
Post back if you decide to DIY the fix and need help.

Good luck… Rich

Hey Nick,

“”Received advice from one of your experts that it was a resistor problem w/instructions to fix. Opened my machine up and the mother board does not match””

That’s not the way I troubleshoot. Did you pull out the troubleshooting guide out of the console, while you had it open it’s good to have the schematic that’s all that advice was good for.

Do you take any errors to the display such as dc/UC while the wash cycle moves into spin cycle? If you run a Spin Only Cycle with no clothes in the wash basket will it complete the cycle? Does the wash basket spin at all in Spin Only cycle? If it does have you done a Tub Displacement Sensor check? I us this quick check to rule it out.
