Maytag Dishwasher Inoperative

Our Maytag Performa dishwasher doesn’t do anything when you press the buttons on the control panel. No lights, nothing.

About a year ago I replaced the door latch (latch had broken) & switches with new ones, and it was working good. Then this.

I cannot figure out, by looking at parts breakdowns, exactly “which” part I need to buy for it to work again. Are there any general control testing procedures with specs for this model dishwasher? If the control panel doesn’t work, is it the panel itself, or the control board? I have info on testing everything but the control panel/board.

Any help would be greatly appreciated. Thanks!

If everything is dead, the first thing you may want to check is the power to the dishwasher.

Check for 120 VAC at the wall outlet.

Remove the bottom panel and check the wires at the junction box (#19 & #21 on the diagram). Make sure the black wire from the power cord is connected to the dishwasher black wire.

Check for 120 VAC to the door switches.
