    Hello labtechrecru, If it’s a FAV6800A/FAV9800A I feel you are experiencing a classic clutch malfunction with this washer and I believe I can help you. Do you want to try a DIY fix? Only basic mechanical skill sets are required to remove the clutch, inspect, and possibly clean up the roller bearings in the clutch. If you call in a repair service I estimate the cost to be around $300 for parts & labor to replace the clutch if that is the part causing the UC error in spin cycle. We will confirm with some basic checks from the Service Manual. If it’s a clutch malfunction and bearing clean up/re-lube resolve the issue I estimate the DIY repair cost to be under $10 or less, $0 if you have a can of WD-40 and a grease gun in the house. Let’s confirm your model number and the first two digits of your serial number of your machine. That info is located on the top right back side of the washer console. Give some thought to your ability to tolerate some down time if you go with a DIY fix. I can also help with some phone support.

Hello plthrsn64 ,
You should open up a separate problem for this but I will post as a solution for the Lid Lock Issue.

For the FAV6800AW that is you machine type correct? The "LO" console error is "Lid has failed to unlock". I haven't experienced the "LO" error code to the display but this is the direction I would go in. I feel you have a signaling problem back to the control board in the console from the lid is unlocked contacts in the left/right Lid Locks.. I would disconnect the left and right lid lock plugs to the washer. The right lid lock is not necessary for operation. The left lid lock is the important one because of its dual signaling function, the Lid is closed signaling from the magnetic reed relay and lid magnet and the lid is locked signaling from lid locks slide switch in the lid lock. I think you may corrosion build up in the left lid lock such as the Pic’s I will attach show of other users. The left lid lock is subject to corrosion brought on by the bleach dispenser.


You can start by un-seating the right lid lock and leave off. Then try un-seating and re-seating the left lid lock plug a few times and see if that will get you back in service. Be careful those plugs are difficult to pull out. Please remove power to the washer first then you will need to lift up the washer top to access the lid lock plugs. Here is the process, use the service manual for additional support.

The Service Manual for reference. Sears Parts Direct for reference.
Raise the top of the machine. Insert a flat blade putty knife approximately 2.5” from the left and right sides of the washer top, depress the spring tabs securing machine top to the washer base. See page 33 of the SM for putty knife insertion point.

If seating/reseating the left Lid Lock a few times doesn’t help I would remove the left lid lock per the Service Manual, carefully open up the left lid lock and see if corrosion is the issue. The plastic latchs around the lid lock enclosure can break off very easily be careful when opening the lid lock. If you have severe corrision I would use some WD-40 to clean up the contacts with a Q-Tip. The cntacts for the Lid is locked slide back and forth with the activation of the solenoid in the lid lock. You may have to rock back and forth the solenoid to clean up the slide switch. Just watch how the relay parts sit in the lock the latch arm will come out and you will have to fit back together to operate correctly. Sounds complicated it is not, it's just difficult to explain. If you have to replace the left lid lock here is a link.

It shows the letters LL


LL = Lareg Load Detected.

I think you may have some drive system resistance/binding. This can be difficult error code to troubleshoot with knowing more info.

What was in the wash basket that caused the LL error code?

Have you tried to power cycle the washer (remove 120VAC line Cord then plug back in)?

Any unballance error codes like dc or UC in the past.

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

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

I have an error code uc in the spin cycle what could be causing the problem?


uC = a continuous unbalance condition of the wash load.

Because you are posting in the Fixya Neptune FAV6800AW Top Load Washer forum I’m going to assume your machine type is a FAV6800A or FAV9800A.

For those machine types I feel you are experiencing a clutch malfunction. Can you confirm the machine model number and let me know if you want to try a DIY repair. You only need basic hand tools and skill sets to repair. See this post for what is involved and this a most recent post of a forum members repair for a dC error code condition in Spin Cycle which related to the uC error code in Spin Cycle.

Error code of "dc" on my TL Maytag Neptune


If your machine is FAV6800AW or FAV9800AW the dc/UC errors are caused by a clutch malfunction. Your machine is shutting down with those errors so your Tub Displacement Sensor is working as designed.

Fix the Clutch malfunction and you can wash a single sock or a load of blue jeans and you will not take the dc or UC unbalance errors. See this post for the fix.

Post back if you have questions or need help.

Uc code error


uc code means unbalanced condition. My research shows this as being an unbalanced load or a faulty control board.
Make sure your load is balanced, otherwise you may have to replace the control board.
