MAYTAG WASHER MHWE400WW01 WON'T LIGHT UP

[TorontoGrasshopper]

Hi Everyone,

 

I have a Maytag washer MWHE400WW01  It is the 4000 series are here are the Symptoms:

*  Cannot get any lights on the control panel (touch pad / LED assy)  to come on at all except that the "Control Lock" feature seems to work and light up and chimes

*  When pressing the power button I get 3 short chimes and that is it - nothing else (except the control lock light)  lights up at all - Zilch!

*  Cannot get it into diagnostic mode(s) at all as nothing happens

* I checked the "door switch" (not the door lock switch) and I get continuity across the switch when pressed

* When plugging and unplugging the power cord I get clicking from the CCU

 

Any common problems that may cause these symptoms?

 

Thanks in advance

Tom

Have you tried to turn off the control lock?

Yes I can turn it on and I can turn it off but that is about all I can do.  It makes no difference if it is on or off.

Remove the bottom panel and unplug the blue 3 wire connector from the motor control board on the lower left, if the unit now powers up you need a new board

Need a new Central Control Unit Board or Motor control unit board?

I did what you said and you were correct.  After removing the 3 wire blue connector the Front panel lite up like a Christmas tree but of course it did nothing but at least it shows the MCU is the problem.  Am going to get another!!   Thx so Much!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
