About a week ago my Bosch dishwasher started to make a continuous squeaking noise throughout pretty much all of the cycle. I've heard this noise occasionally in the past for short periods, but this is a new thing where it's doing it every night and through the whole cycle. Audio clip here https://clyp.it/xz1redra

Help?

To me it sounds like something caught in the pump impeller. My hearing is not what it use to be so I can't be sure but I would check that first.

Yes, I agree with Rick.

Whew, that does not look like a trivial project! Okay, before I take it on, let me give a little update and ask what you think. The past two nights, the squeaking/squealing has been less continuous ... it's been on for several minutes and then off for 10, 20 minutes, then back on for several minutes. Does this have any bearing on your diagnosis?

Not really, it could be a piece of glass or a piece of plastic that gets lodged somewhere and then dislodged. It could be the motor itself that's making the noise. It's too hard to tell.

Can you access, or see, this impeller from the top, or do you need to remove the pump to check it out?

You'll need to remove the pump. Working on Bosch machines is a nightmare if you ask me,,,lol

Sounds to me like for a 13 year old DW, which this is, if you go to the trouble to remove the pump, it probably should be replaced with a new one at that point. No?

We have had no trouble with this DW, but I know every appliance has a lifetime, especially one with all the electronic controls (SHU66C07UC). I'm hoping to keep it running as long as possible as the color is no longer available so we would have trouble matching the kitchen.

If that's where the problem is otherwise you'll end up with a machine that has a new pump but doesn't work.
