Nd in the display

Are you sure this is not an nd and not an np flash code? If so then the code stands for no drain, likely something is clogging the washer pump inlet.

If the individual part/function CAN work, but it wont complete a cycle, suspect the control board...

Jim try running a dry,meaning without a load. see if it works all features to full cycle.

Google this Neptune TL Washer FAV6800AWW

You will find FAV6800A or FAV8800A help. I would not by a Control Board or any part until more trouble shooting is completed. We need to make sure you can get into Service Mode nd do some basic checks.

ND is no drain error code for the FAV6800A and most Maytag machines.

Is there water in the Wash Basket. If not this could be a stuck Pressure Switch. If there is water in the Wash Basket then there could be a Drain Pump issue/Drain Line clog.

If you want to DIY I can help you.

Hello.
That code is telling you that the unit is draining to slow. After 15 minutes it is not below the low water level and will not spin out. The best repair for this is to replaced the pump on your unit.

Hello HopelessR,
Don’t buy a clutch I don’t feel it’s a clutch issue at this point. I hope you can hang in there for some basic troubleshooting. I’m an owner like you not a repair person but I have worked some issues. I feel with the info supplied that you have a true “nd” alarm. The “nd” alarm is triggered when the washer fails to drain completely as monitored by the pressure switch input to the control board and the factory program time limit required for draining the washer. I have never experienced an “nd” alarm until this evening. This was a user induced “nd” failure by pumping wash water back into the tub during the drain cycle of Quick Wash cycle. I started a Quick Wash cycle with no clothes in the washer and with the remaining three settings set to min settings. At the 22 min mark the washer started the drain pump and began a slow spin CCW of the wash basket. It took several minutes of pumping wash water back into the wash tub to trigger “nd” alarm. The washer indicated time stayed at the 21 min mark until the “nd” alarm triggered. 1st test; could you start a Quick Wash cycle with what you would consider a full wash load with the settings I mentioned and let’s see what the results are. I don’t feel you have a clutch issue with no dc/UC error codes to the console. I believe at this point that you have a drain restriction problem. I can’t explain why the washer completes the cycle with the wash basket empty at this point. The 2nd test, do you have a deep sink you can pump the wash water into and observe the stream output? The stream my FAV6800AWW will produce is about a 3” vertical column of water out of the drain pipe held over the deep sink with the drain pump running and no clothes in the wash basket. If you have a deep sink and a helper that can turn on the drain pump in service mode as outlined below we can compare your drain pump output to mine.
You can turn on the drain pump in Service Mode with the process below.
1. Enter Service Mode by pressing both the Enviro Plus and Spin Only keys simultaneously until the washer beeps.

2. Next you need to go into the Board Output Test by pressing the Delicates key; your display should now read “ot”.

3. Now press the Presoak key this will start the drain pump and it should begin to empty the tub.

You can press the Off button to stop the drain pump.
If the output stream is low we can troubleshoot the restriction starting at the Sump Cap Item 9 and work back toward the drain pump.
I’ll hang in there with you if you want to continue to troubleshoot the issue. Maybe we can get some suggestions from other forum members. Rich

some of those pumps had a small hose going to it from the water level control have had trash pulg them up on pump end and at pump port ck it ..if pluged control may thing washer has enough water and will not let any in also pump may have gone kaflooey

nd= no drain. loud buzzing noise sounds like something stuck in pump assy.remove the door(2screws) adn other 2 screws oppisite side, and hte front panel comes off giving you acess to the drain pump, pull the hoses and look for the obstruction
