In Topic: Maytag Dishwasher: No Water

21 January 2015 - 10:40 AM

Also, Have you tried applying 120VAC to the valve directly to see if it operates?

 

Chat, thanks, actually I already replaced the valve with a brand new one because I thought that was the problem.  This was before I bought a multimeter and tested to find out there is no current going to the valve.

 

Folks, can somebody tell me if there is a foolproof way to test the main control board?  Someone on another forum said this is the most likely culprit, but I've already bought one part that wasn't broken and the control board for this model is about $150 online.

 

Is there a way I can test the main control board while still in the dishwasher, or do I need to remove it to test it?

 

Thanks Very Much,

Educated Guess

Just a thought, Maytag had problems with the rinse aid dispenser leaking onto wire harness inside door.  Harness would swell up and break.  May want to seperate door liner from door and check condition of wires going through bottom of door.

Elmond, thanks, sounds like a good idea.  Someone else recommended something similar to me.  I kinda tend to doubt it's this main control unit, so I'll check this out when I have a little more time.  Thanks so much for your input.

You need to check for voltage at the control to eliminate everything between the control and the valve, first.  No voltage, bad control, voltage bad wiring connector or float switch.

 

Spanner, thanks again.  Someone said it could also just be a broken wire, so I'll have to check the whole path.

 

I did have one question.  At the beginning of the cycle, when the water should be coming in, I've toggled the float up and down so the float switch is alternately connected and then not connected.  Shouldn't the intake water valve shut down when the switch is connected?  It doesn't seem to have any affect on the operation of the machine, one way or another.

 

Thank You!

The valve doesn't receive voltage the entire time the unit is running, you need to check at the very beginning of the cycle.

 Spanner, thanks.  Actually, that's precisely what I did.  I started the machine from the very beginning (when the water would normally be entering the unit), and sat there for about 15 minutes on a chair while it cycled through all the beginning stages.  No voltage. 

 

I just wanna make sure I need to replace the main control board -- that I've correctly diagnosed the problem -- since the part is about $150+.

 

Thanks for your feedback.

Are you checking the voltage to the valve while the dishwasher is running?

 

John, yes, the machine was engaged and running and cycling normally when I checked the voltage to the water inlet valve and received a zero reading.  Someone on another forum told me this means the problem is the main control board for the machine, which costs more than $200.  If that's the case, I wonder if I should just buy a brand new dishwasher.
