H20 code but it is filling with water. Just 3 years old now, I believe. I was going to check the pressure switch but there’s no tutorial and the diagrams aren’t too clear - do I gather I pull out the dishwasher, unscrew the bottom plate retaining screws, remove the plate, and then I should find it on the right hand side, where I can see it? And the pressure switch is fed by hoses, not directly in the thingie?
Should I try a cleaning cycle with vinegar or whatever first? The code’s gone away when I’ve cycled through. I did try cleaning out the sump, and there was some stuff that made it through the filter (probably when I was cleaning the filter—now I know I have to pump that area clear first.)
Been a great dishwasher otherwise, and three years is more than I got from my last KitchenAid before it started breaking down regularly. (It failed twice during warranty, needing new door seals and a new computer, and then the grinder seemed to need cleaning or replacement like clockwork.)
Thanks!! I decided to run a “cleaning cycle” with vinegar and heat boost before moving forward with the purchase, but I might get that assembly proactively. On the other hand, maybe I should try cleaning it before buying a new one. (I’m a long time customer so I don’t feel guilty!)
The pressure sensor does look relatively easy to reach. Your switch box looks just like mine, too I like the “maybe I should drain the water first.” That sounds like me! I use a turkey baster… then the rags.
No freakin’ clips - that’s nice. I hate “push while pulling” (I guess I’ll have to do that on the wire).
THANK YOU!! This is one reason why I come here and never Amazon.
Video was very, very helpful, again. That grease clot is really resistant. I took it out and cleaned all I could get to… but I couldn’t get the back off, mine looks different from the one you show (and which I ordered since the washer code matches up):
Cleaning did not do the trick but I had already ordered a replacement anyway. I’ll try again but the casing is more pry-resistant than the part you’re showing, so I don’t think I’ll be able to get this one going.
Update: I tried a small screwdriver to pry it apart and it looks a lot like your example inside. I’m waiting for it to dry completely and then I’ll put it in and try again, if all else fails I’ll wait for the new one
Final update: Final kudos on a great video. Got the thing apart, cleaned thoroughly, let dry for the electrical connectors, replaced, all working great, no rush to get the replacement part now but I am having one in stock for the future. Maybe I’ll get a water valve too, with my next order…
