Maytag Neptune showing an error code of UC
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.

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.
