This is my failure resolution with DC/UC error codes a common problem with this model;
I just did a repair on my FAV6800AAW by lubricating the needle bearings in the clutch pulley hub, the tub displacement sensor checked OK per the service manual check. I was getting dc/uc errors in the spin cycle, washer was purchased in 7/05. I have basic mechanical skills and used a socket wrench to remove clutch pulley hub, just follow the service manual removal steps to remove clutch pulley hub. Pull the plastic cover off the clutch pulley hub and inspect the spring, clean/lube needle bearings and the clutch hub coupler that drives spinner shaft. I used WD40 I may need to re-lube down the road with a good light grease. It took a few tries for me to get the clutch pulley hub to stay on after re-install and power up, getting the clutch pulley seated properly is the trick. I did not remove the washer tub for this fix, I believe I saw a posting where someone did. I just leaned the washer back to get a better reach angle, it is a tight work area. I did not want to junk 3.5 yr old $1k machine with out trying a fix. If you want to work on this model get the service manual, I found it online and I believe you can order it in PDF format from Maytag. Good luck!
I just went thru my 10th load of a mix of light, medium and heavy loads and all work fine no unbalance errors (DC/UC). Doesn’t fix the tangle problem :) Prior to this fix I could only run the washer with no clothes in it to complete a cycle with no dc/uc error codes.
I found a Service repair manual on this site search for this; FAV6800 Manual

There is a problem with the lid. Push ******* the front of the lid. It should work. Mine has been doing this for 6 years.

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 firstname.lastname@example.org. 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

Hello & Welcome to FixYa
Ld means long drain and is displayed when it takes longer than 5
minutes to pump out the water to a point where the pressure switch resets. To
solve this problem make sure that the drain filter pump assembly located inside
the bottom front panel is clean and after cleaning if the error returns then
the pressure switch needs to be tested and if bad then it needs replacement. The cost will depend on parts and will be around $150. Please get back to me if you have any other questions.

During Drain Routine
During the Drain Routine, the water level is checked continuously. Normal drain will occur until the
pressure switch senses no water in the wash tub and there is no foam (suds). The drain pump will
operate an additional 15 seconds after the pressure switch reports no water or foam.
If the drain routine operates for four (4) minutes and the pressure switch senses any foam (suds) in
the wash tub, the Central Control Unit will start the "Kill-Foam" Routine. (See description of this
Routine below.) After the Kill-foam Routine is concluded, the Drain Routine will restart. If, after
four (4) minutes the pressure switch still senses foam in the wash tub, the Central Control Unit will
go into Failure Mode. The digital display will show, F02.
During Spin (Extract) Routine
During the Spin/Extract Routine the water level is checked continuously. If, during this routine, the
pressure switch senses the presence of foam (suds) in the wash tub, the Central Control Unit will
stop the drive motor and the basket will stop spinning. The electronic control will count the number
of spin repetitions that are attempted due to foam (suds). There are a maximum of three (3)
attempts for each Spin/Extract Routine.
1. The Remaining Time counter is stopped.
2. The digital display shows Sud.
3. The Drain Pump is turned OFF.
4. The Central Control Unit will fill the wash tub with 1 gal. (4 L) of cold water.
5. While the tub is filling the basket will tumble 1 sec. ON/15 Sec. OFF.
6. Once the tub is filled, the drive motor will turn OFF and the basket will rest without any
movement for five (5) minutes.
7. After the five (5) minute rest, the remaining time counter will restart and the digital display
will show the remaining time left in the routine.
NOTE: If the Kill-Foam routine was initiated during a Spin/Extract Routine, the tumbling action
will be reduced to a cycle of 3 sec. ON/13 sec. OFF. If, at the end of either the Drain or Spin/
Extract Routines, a suds condition still remains, the digital display will show Sud.
Sud will also be displayed for a short period at the end of a cycle, if a Suds condition was
detected during the cycle. This will alert the consumer to reduce the amount of detergent in
