Machine tumbles but does not spin up to full speed. I troubleshot IAW Maytag service manual and replaced motor control board from known good machine. Worked fine for a week but now has same problem. Measured motor windings, found them good according to service manual. Measured tach output from motor pins 4 & 5 and found them open, service manual calls for 155-195 ohms. Maytag service manual troubleshooting tree does not address this condition. Is the tach output required for operation or is it used as part of the help mode that provides failure codes? No diagnostic (failure) codes given when using service mode.

What's the results of the Troubleshooting Flowchart on PDF page 90 ?
MAH21PDAWQ Service Manual

Does this have the updated Motor/Controller ?

RegUS_Patoff,

Thanks for the quick reply. The machine does have the updated motor/harness and motor control board installed. Hopefully, my sister/brother in-law will be able to test using the flow chart as recommended tonight.

RegUS_Patoff,

The machine did have the updated motor and control board. You would not believe it. There was enough change left in the machine from someones pockets that it got past the pump and clogged the output hose. There were no error codes that pointed to slow drain. Anyway, there was so much change in the outlet hose that I had to drive it all out with a pipe. Machine works like a champ now.
