PRESS BUTTONS TO TURN MACHINE ON , LIGHT COMES ON BUT NOTHING HAPPEN THEN LIGHT GOES OFF.

Here in order is what must take place before the water valve will come on.
But first shut power down at the breaker/fuse box for 5 minutes , then power back up. Try the other cycle buttons to see if you they will accept your commands. Do any other lights come on? If yes....will any other cycles work? Try them all please.

If the control panel will not accept any commands then the control is most probably fried.


1.) have power going to the control....that is confirmed.
2.) there are two door switches that must be made....one allows power to the control board....we know that the switch is made because we have power to the control.
3.) you will need to confirm power to the other switch just opposite of the l1 switch that supplies power to the control panel. Here is a link to your wiring schematic and parts drawings.Click on the link http://www.searspartsdirect.com/partsdirect/part-model/Maytag-Parts/Dishwasher-Parts/Model-MDBH945AWS/3048/0130000?pathTaken=&prst=0&shdMod=MDBH945AWS
4.)There is a float that is located in your tub.....ensure this float is not in the up position.....it is a safety for not allowing to much water into the tub....if it is in the up position the water valve will not come on. Move it up and down to ensure it moves freely. If it does just below the float under the tub is a float switch that will be needed checked.

If you would like instructions on how to use a volt meter and how to check the switches listed above please post.
