on starting cycle water seems to fill but when wash should be starting there is simply a hmmm as the motor seems like it wants to start..it goes off and tries again in a few seconds...almost sounds like its jammed....tried to see if there was blockage but maybe i am looking at wrong place? I know where the drain impeller is and that is fine and draining works when i cancel. I have removed and checked control module for circuit board burns but didnt see any....this machine gets very little use. all thoughts appreciated.

Most likely the problem is a bad wash pump (aka circulation pump).

In order to replace it the dishwasher has to be removed from the cabinet.

- The part number for the circulation pump is AP2826384

are you certain that there is no way some clog could be doing this...although 5 years old the machine has probably been used less than once a week....not much wear

thanks again

if you know where to access the circ pump impeller, you can use a either a 5/16 hex nut driver or a 5/16 socket , insert it where the impeller is and it should lock on , then you can turn the impeller for yourself ... if it is free , then the circ pump motor will need to be changed like Gene said ..

Thanks, kawfeeman... that would seem to clinch it....but can i get to the impeller at all from either inside the dishwasher or via the kickpanel....or do i actually have to turn the machine upside down to get to the motor itself to try this out....

many thanks again to all...

[kawfeeman]

sure , you can access the impeller( just to turn it, not to remove it ) from inside .. remove filter assembly and there is a hole on right side in sump where you should be able to access the impeller ...

Thanks...that was very helpful....the impeller seems jammed though i could find no debris....even with a tool i was barely able to turn it....i happen to have a second machine which works and could check against that one and in the good machine the impeller spins pretty freely.

so does that mean the circ pump or is there something inbetween i can do.

thanks again

If there is nothing wrong with the motor, then you can fix the circulation pump using the repair kit.

The dishwasher has to be removed from the cabinet and the base has to be removed from the dishwasher to get access to the pump.

- The part number for the repair kit is AP2802376

Thanks again....here is something else that might be useful in the future...i've been told that the pumps do tend to seize when not in use...there were long periods of non-use.....and that the seize can be broken (Bosch apparently teaches techs this) by using an 8mm socket on the impeller from inside the dishwash below the screen (where you would normally check for debris). Using the socket on a ratchet, i was able to turn the impeller, but not really loosen it. So looks like the rebuild kit will come in handy. Thanks again.
