Maytag model # DWU9200AAX

 :-\I'm at wits end here. My machine just keeps tripping the circuit breaker. If I reset it immediately trips again. I do not have the manual, so I can't address the problem. Not sure what parts need to be purchased......any ideas?

Here is the service manual, just added it for you.


16007823 Maytag Dishwasher Service Manual

You may want to remove the access panel that is below the door and look inside the junction box that the power cord goes to.

Check the wires where the cord connects in the box under the bottom panel. I have seen that being the most common problem. Cut the wires back until shiny clean and use new wire nuts.

Thanks so much for the service manual, been browsing the intrawebs for nearly a week now and couldn't find anything. Will do some diagnosing tomorrow and let you know the outcome. Its definitely frustrating. Last time it got all the way to the rinse cycle and then quit.

I had one recently with a hole in the drain hose.  Water was spraying directly at the outlet the dishwasher was plugged into.  It was very intermittent, sometimes it would go an entire cycle without tripping the breaker, sometimes it would trip right away. That was a real head-scratcher until I finally pulled the dishwasher and found the leak.

Wow, Ok so its been a real scary endeavor digging into stuff and finding things like this....





Note:
The duct tape is just temporary to test the unit. I need to buy some electrical tape and better butt connectors.

I guess the Jet-Dry unit is toast, even though we never use it.
The yellow wire on the heating element had some overheating issues as well.

Despite all this, I still cant seem to get past the original problem. The water valve is not activating at the 120 second mark.
I tested the float switch for continuity and all is well there. The switch is functioning properly.
I tested the resistance of the water valve, it was within spec.
Removed the water valve and cleaned it up, then tested with a direct 120volt line and it functioned as intended.
Re-installed the water valve into the unit and connected the water then applied 120 volts through a kitchen outlet and the switch worked as intended.
Next step was to check for 120volt at the water valve terminals at the 120second mark into the start of the wash cycle. No dice there.
Seems that the main control unit is not commanding the valve to open. Cant find a relay that drives this specific module. Not really sure where to go from here. The control module could be pricey and after finding the evidence of the short behind the panel, the question may become whether or not to replace the unit all together.

I have the same machine and an extra just like it so I can keep it forever. I have not seen another dishwasher that cleans as well as this unit. Yes it's noisy but it really cleans the dishes. In the past I have had Kitchen Aid and a Whirlpool. Maytag for me,and I don't mean a Whirlpool with a Maytag label like the new ones. I would check for bad wires (check for continuity) also I would ignore the dispenser and use tablets.
