Hello all, I found this absolutely beautiful Whirlpool dishwasher recently and would like to share. The model # is DU8770XY-1 and the serial # is FC3858582. I believe it is a 1993. The machine appears to be very low use. The previous owner had it set up in bisque, so the black is just pristine. I decided to take the pump assembly out and it was pretty crusty. I managed to get it somewhat cleaned up though. Is there supposed to be a gasket under that little grey pump cover?? My kit didn't come with one. I left the bottom pump impeller alone as it seemed pressed on and I didn't want to break it. I broke the wash impeller on the way in, so I had to use the replacement part. Unfortunately the replacement part sits a bit taller as you can see in the photo. I decided to cut down the difference with a hacksaw to stay true to original form as much as possible. The macerator and the metal collar were also different so I ended up reusing the original ones. They must be for a newer iteration of the PowerClean? The stack-up for the spring/collar/macerator seemed really tight, and I know nothing about working on these PCs so I definitely didn't want to experiment with mix and match.
After I finally got the machine cleaned up and put back together, I could not get it to cycle through at all. Imagine my frustration! The thermostat and heating element both proved to be good, so I had no choice but to tear into the timer. I was pretty happy to find that it was nearly cracked in half. My guess is that the timer on this machine broke a long time ago and that it sat unused ever since. That explains the seemingly low usage- but who knows. Luckily I bought a spare timer the moment I picked up this machine and it actually was the correct one and worked. I just didn't know how quickly I would be needing it. I have ran the maiden load through it and the machine seems to run perfectly now. I'm sure other problems will creep up, but it's fun to have a real DW again. The only thing I've noticed is that there remains a little bit of water left over in the sump after the cycle completes. Is this normal??
