I’ve done some troubleshooting, but need some advice. Here’s a repeatable scenario:
[LIST=1]
*]Start "Rinse Only" cycle
*]Dishwasher starts filling (after "sensing")
*]If open door (before cycle rinse cycle begins), diswasher keeps filling while door is open
*]Eventually rinsing begins, but filling continues
*]Water overflows
*]Press Cancel and water will stop filling (and cycle ends)
*]Water is drained via pump[/LIST]I’ve tested the float switch for continuity and it appears to be working normally. BTW, if I trigger the switch while filling, the water does not stop filling. I’d suspect the valve, but it actually seems to be working normal with cycle start/cancel. Perhaps a circuit board issue??
You seem to be missing a few digits at the end of your model number.
I agree with you that it does sound like the water valve is being turned on and then sticking open…
De-activating the float switch should shut the water valve off even if the control board is supplying power to it, same goes for the door switches. so I doubt that the board is your problem.
What you could do to double check this, is to measure the voltage across the water valve when running (120 volts). Then de-activate the float switch, if the voltage drops to 0 but water keeps running then the valve is toast for sure.
