My maytag dishwasher recently stopped draining. I removed it to see what the problem was and found that the drain pump had been shorted out and rusted due to a crack in the plastic dishwasher body. I bought and installed a new pump. When the power to the dishwasher is turned on and the door is closed the pump will run constantly. It does not matter if the dishwasher is in a cycle or not. When a cycle starts the dishwasher never starts due to this constant draining. I have tried connecting the pump both ways (reversing the colors of the wires) as well as checking the amount of oHm’s across the leads. According to the service manual the pump is reading the correct amount (~25oHm). Outside of the control board no longer functioning I don’t know what could be causing this. Any information on similar experiances or ideas would be welcome. Thank you.
Could be when the old pump shorted out it welded the contact together on the relay that controls the motor.
no relay in schematic only capacitor
The relay or may be a triac will be on the control board
any way to jump this out?
Not really.
Cannot get actual schematics of the boards so they are replacement items.
Triac can be replaced I examined board and ordered what I belive to be triac will soldier it in and let you know results when it arrives thanks for all of you help .

If you need a comparison search the web for semiconductor replacement guide. The websites from NTE and ECG are pretty good. I have an old ECG book but the websites have a lot more information and better cross referencing.
Thanx appreciate all your input very helpful .

Soldered new triac on control board and it solved the pump problem of non stop running ,dishwasher now operates flawlessly, thanks for all of your input.
