Hoping someone can help. I recently purchased an inlet valve replacement, part 9744468, for the (old) dishwasher above.

The old inlet valve stopped opening, though the rest of the cycle seemed to run, so I thought replacing it would be straightforward. I checked the wire harness, and it has 120V when it the valve should be open.

When I connect the new inlet valve to the dishwasher and try to start the cycl, the dishwasher immediately seems to turn off. Tried it a number of times, thought I heard the valve make noise once or twice, but most times nothing happens but the lights go out on the panel.

I reconnected the old valve to the electric harness, and the dishwasher still stays on (though that valve doesn't make any noise when it should be triggered to open).

Did I get a dud valve? Is it possible the electrical changed? The old valve part number is 9743559, and I've seen the one I ordered online as a valid replacement, so I'm stumped.

Thanks in advance

Thanks for the reply. I will have to check the resistance over the weekend.

One question - you mentioned to check the metal body of the valve to make sure it is not grounded. It is attached to the frame by a metal screw, and there is a ground wire running to the frame, so I assume it is actually grounded to the frame of the washer (though I could be wrong) - the old one was connected to the frame the same way. Is that the part you are suggesting to double check?

Thanks again

Thanks - checked the resistance - it looks like 900 ohms or so across the two leads that connect to the wire harness, and not grounded to the frame from those leads. The old valve, for what its worth, has infinite resistance across the leads, which I assume confirms something burned out inside it.

But still, when I hit the start button on the control panel it immediately turns off. I've tried attaching the leads after hitting start (I know, not the safest thing), and sometimes I'll heard a slight whooshing before it shuts off, like the valve is moving a hair, but no matter what it immediately shuts off.

I guess that means I'm facing a controller board problem on top of the broken valve? If so, I think I'll have to move on to a new dishwasher, as I'm not sure replacing that on a unit this old is cost effective...
