Going on a call today on a maytag washer that just beeps when the start button is pressed. All the power and lights work fine just doesnt start the cycle. Mod# mhwe200xw00. Im thinking its a possible door latch issue. What do you guys think?

Provided child lock not engaged, could be door latch P/N W10253483.  Fault code F5E1, F5E2 or F5E3 should show in diagnostic.  I also see a microswitch down on the left side of access panel that's not on the wiring diagram.  Hmmm....

Could also be a failed motor control board. If the motor control board is bad the machine won't even fill with water.

Bro Scott,  what's that switch at the access panel?  It shows on the ipl but not on the diagram.  I haven't seen it in the field.  Is it a safety?

Yes, there is a 3 wire blue harness that runs from the CCU (Central Control Unit) to the MCU (Motor Control Unit) I believe it is the M3 connector. Unplug that connector at either end and let it hang. Now hit start, if the unit locks the door and acts like it is going to take off on it's little merry way, you have a bad motor control board. Chances are with this disconected after a minute or so a code will pop, but you will already have your answer. At the moment of start the CCU looks for two signals, door lock and motor control. If it does not see what it likes it tripple beeps. Removing the harness eliminates the bad signal. It will lock the door now and sit there looking for the MCU signal. No signal is better than a bad signal! Make sure you ohm your motor to verify it is not shorted and the source of the blown board though!

So it still didn't lock the door with the blue wire harness disconnected from the MCU?  If not, I'm thinking Brother PDuff called the dance steps on this pig-dog:  http://www.repaircli...0253483/1515091

 

If, OTOH, it did lock the door with the MCU disconnected, then Brother TTH called the ball:  http://www.repaircli...ber=MHWE200XW00

Old tech trick for checking CCU's was to unplug unit and plug back in.  If you hear a click from the CCU then the CCU was usually ok.  But I think these new CCU's are onto that trick.  Still researching that switch at access panel.  I don't know if it would cause a problem but it has attracted my attention.  Will advise.

I had a door switch in the truck so I just put it in to test it. Even with the new latch, it still wouldnt lock. I tried with the mcu plugged and unpluged. No broken wires. Wouldnt run the auto test cycle because the door wouldnt lock. Also there was no error codes (even with the mcu unplugged) ???

Troubleshooting technique for checking the MCU in a Whirlpool Duet Sport washer

By Samurai Appliance Repair Man in Samurai Appliance Repair Man's Blog, on 23 May 2013 - 07:24 AM

If you're dealing with a Whirlpool Duet Sport front load washer (also sold under the Maytag and Kenmore brands) that just beeps when you press the start button but doesn't lock the door or run, it can be tricky to figure what the problem is. The prime suspects are: CCU (central control unit), MCU (motor control unit), and the door latch assembly. Academy...
