While in wash cycle, timer counts down to fast   and skips alot of the wash cycle.  You can watch it move and the timer makes a noise. Is this the timer or a board? Which Board?

Timers can make weird noises.

Which part or parts of the cycle is it skipping?  Is it the same part of the cycle everytime?

It skips parts of each wash cycle. If you have it on heavy it skips alot of it, then skips alot of med. and alot of  the light setting. This model has a knob and the selector passes through each cycle when it is set to heavy. It does the same thing if you would put on med.. It would skip alot of med and alot of light. If you put it on light, it skips alot of light.

Thanks

When you say its skips, is it like it's fast-forwarding through portions of the cycle or does the time advance at its normal rate but nothing is happening?

It's fast-forwarding through portions of the cycle. You can watch it move rather fast making  a noise from the timer. Can not tell if it is grinding or if that is what it is supposed to sound like.

 

My wife just said she thinks the bleach dispenser is not dispensing also.

Is this done electronically or with water and a venturi action?

Machine control board (Maytag p/n 22002989, located in the console) controls the timer motor. I wouldn't worry about the timer noise, these tend to be noisier than most.

The bleach dispenser is also controlled from this board, sounds like something's got whacked out. Check the board for any obvious damage (burnt components).

Mad Mac....Pray to God he's out there....somewhere.

Yes, the timer behavior you're describing is consistent with what Mac is talking about.  Here's an excerpt from the tech manual:

maytag has a problem with that curcit board there is a weak spot on the board that that will produce a burn spot in the location of the problem behind the timer the control board board must be replaced  ( refer to the maytag consumer law suit )

Thanks for the info.

Somehow My wife got Maytag to come out and fix problem for free with help of a nice repairman.

He replaced main board, motor( new motor that revs 500 rpm faster and is quieter) and motor board, wax motor and seal, all for freeeee!

It appears to be working okay, maybe.

The bleach dispenser timing is in question. The timing chart appears to say  the dispenser should put water into the tray at the end of light cycle and it only stays in a minute and then it drains.

Is this correct?

thanks
