I have a fav6800aww maytag neptune stop durring cycle

Hello mttwtkns,
I’m an owner like you; from what you describe I feel you have a clutch issue. You don’t mention dc or UC errors when the spin cycle fails in Quick Wash cycle or any wash cycle. The 22 min mark in Quick Wash cycle is the start of the first spin cycle. What most owners don’t realize is this machine is designed to begin the spin cycle with a fair amount of water in the wash tub. When it fails in spin cycle because of unbalance errors they report the machine failed to drain properly. I believe the Maytag design team designed the firmware in the Control Board to do this to help dampen out tub oscillations at the start of the spin cycle. You are one of a few owners that have taken the SM and used the Control Board diags to troubleshoot. Good job!!! and very refreshing to hear. See this post for a step by step process to remove the clutch. Try a maintenance clean up of the Oneway Roller Clutch bearing and see if that will get you back in service, if not I would do a Clutch replacement. My machine is a series 16 doesn’t use the upper one-way roller clutch bearing. You series of machine is the 1ST two numbers of your serial number of the machine. Some parts are seria number/series dependent.
Don’t get hung up on the pressure switch. It sets on top of the drain pump. You can test as you know in Service Mode thru the board input testing of page 16 of the SM. Just fill with a few buckets of water until you see the transition -0 to -1 for low level. That’s about 3.5 inches of water in the wash Basket. Then as you stated turn on the drain pump in Service Mode to pump out the wash tub. Your drain pump is fine as you have already tested. I have a post on a retrofit of the Sump Cap where I installed a stainless steel screen to protect the pump impeller from coins and other trash. Again I feel you have a clutch issue, I would like to see dc/UC errors to the display for this fail to spin issue. Are you sure you are not taken those unbalance errors to the display?. You could also go into Service Mode and read all the error codes. See page 25/26 for unbalance diag error code blocks 5 and 10. Post back if you need additional help. Rich

is it failing in the rinse cyc if so are you getting proper water flow on both the hot and or cold but when you state that you pulled the clutch? do you mean the pully wheel. if the unit if failing to drain all the way it will not advance for the remainder of the cyc check you water pump to ensure its pumping properly of if an coin has gotten in pump it may have chewed the inpellers and replacement is req

The Problem IS the clutch.
to verify the problem you should get a putty knife and open the top of the machine by releasing clips at the font left and right approx 6 inches in, you push the clips in with the putty knife and lift the corner of the top, it is a good idea to tape the lid shut first, hold the corner that you start with up while releasing the other side.
Once you have the top lifted, start the machine in a spin cycle, if the paddles move at all before or at the start of the spin cycle you will notice that the clothes are being pulled up one side of the tub, this is caused by the slipping clutch.
the load goes off balance and triggers the machine to shut down and reorganize the load. it will do it several times and then shut down usually with an eventual UL code.
replace the clutch, and you should see improvement, be aware that the new clutch will come with a plastic yellowish or white adapter, if yours had the adapter use it with the new one if it did not then remove it, make sure that the clutch assy is all the way up and secure.
Good luck.
