After 4 years of almost daily use, my MDB7601AWB will not start. We can select the cycle:
The time then appears flashing on the front panel, waiting for you to close the door and press <Start>:
Nothing happens, however when you push either button on the front panel, <Start> or <Delay>. Since that is the exact same way it acts when the door is open, I pulled the connectors from both door switches and tested them first. Both are working normally.
I found the gasket that seals the steam vent to the outer door shell was off-center when the door was assembled:
This would have allowed steam to enter the door cavity on every wash cycle. There is some evidence of the effects from the steam inside the door: The foam paper insulation is drooping on that side from being wet and heavy:
And the thick insulation foam strip (PN AP4263539) has deformed, separated from the door and is also drooping down:
I cleaned the ends on both of the ribbon cables:
But the problem persists. Is there anything else I can check? Thanks in advance for your assistance!
[SIDEBAR: The steam vent gasket problem was probably initiated a year or two ago when a repairman came out to take care of recall work. I think the inside door panel and the control board were replaced due to fire concerns. That visit probably created this problem. Not that it makes a difference today…]
Joe, Thanks you for the quick reply. I found the data sheet, I was able to test the door latch with the door closed. I was also able to test the control board by disconnecting the ribbbon cable from the key pad, then restore power the unit started the drain cycle. The LEDS on the key pad passed the test with the sevice diag. test. I tried the keyswitch resistance testing without success, even on a known good key/button would not measure any resistance. I thought I read somewhere that this tesy may not be valid for all keypads? Any ideas?
Thanks again
Final Report: After confirming that the front keypad was bad (using the test information on the data sheet) I ordered a new Control Panel from Appliance Parts Pros. I placed the order on a Saturday night and was told it would ship on Monday.
I received the part on Wednesday (with standard shipping), the dishwasher was working about an hour later, and my wife was smiling again. Remember guys, if mama ain’t happy - ain’t nobody happy!

I have a maytag dishwasher model#mdb7609awb2 when I try to start it it doesen’t come on. I press the digital display and the lighted panel shows that it is working but when I enter the start button it will not light up or start.maybe it has to be reset but I don’t know how to reset it.

Norm,
Sorry, but no there is no "reset" program or device on your dishwasher.
You’ll need to start by Checking the keyad operation, You most likely have a faulty "start" keypad,
[part]AP4434653[/part]
Since everything else programs and works.
You’ll find the tech data information sheet attached to frame or the backside on the kickplate assembly, That will allow you to test and verify the operation of the dishwasher.
