No more squirty/sudsy/washy.... I can see the water going in from the side of the now open to the world (since my old fridge failed) dishwasher. But I can also hear the water being sucked straight down the drain (and the drain gets warm). I had a mouse get in there and was electrocuted on some contacts, but they don't seem to be drain solenoid contacts, too high up. Not sure what they are exactly.

Is this now scrap? I have to admit I've never seen one of those central control boxes before, which appears to be a combination of relays and a music box (cam).

You'll have to turn your head clockwise or screen counter clockwise to see the mouse pic properly. Sorry, at least it's clear.

The drain valve is probably shorted open.

Really nice machine. Will clean circles around most of the junk on the market today------ once it is operating properly.

So how do you fix a shorted out drain valve?

Post# 968967 , Reply# 5   11/19/2017 at 18:45 by Tomturbomatic (Beltsville, MD)        

I would start by disconnecting the power from the machine and then removing the mouse. Reconnect the power then see what happens.

Did that. Cleaned contacts with a toothbrush. No luck.

Well, I will be opening the place up again soon. Wondering if anyone has any other suggestions for how to fix this thing? Should I just buy a new/used one off of Craigslist?

Something is in the drain valve keeping it from closing. Open it up could be a bit of glass toothpick etc. Easy fix.

Get some clip leads and a volt meter and find out if the solenoid is truly energized or that something is just sticking the valve open.

If the drain solenoid is getting line voltage during the fill, you have an electrical problem, if not, you have a mechanical problem like eronie suggested.

I did take the entire thing apart from the inside and found nothing blocking the drain. Any idea on that dishwasher where the drain solenoid is located? The mouse was way up high, not near the drain. And line power OPENS the solenoid? Thanks - not my area of expertise.

What did you take apart...

if you are asking where the drain valve is located? The drain valve is located on the lower cross member right in the middle of it. You should see a black, plastic coil with 2 wires going to it and a hose connecting it to the motor and one hose going to the drain. Take that apart and see if anything is in it.

Or try pinching the drain hose with a pliers and see if the water stays in the tub. If it does, then you have something stuck in the valve or the rubber of the sealing plunger is worn out and the valve needs to be replaced.
