Hi, I have a Bosch SHU9925UC12 dishwasher. Water pumps in but the arms do not move. Water pumps out just fine. I took apart the plate and basket, vacuumed out the water, pulled the screw and vaccumed by the impeller (blue plastic) which turns freely. The port on the right is the circulation pump. I can turn it freely with my finger. I put the shop vac on exhaust mode and sealed it to the hole that would feed the arms. It blew air through the port on the right and caused the pump vanes to spin very quickly, no motor resistance. New circulation pump?
ANSWER Hello Mike,
I believe you are correct in the diagnosis of the circulation pump 00239144 as long as it is getting voltage. Replacing the pump won't fix it if it isn't getting voltage. I would make sure voltage is getting to it when it should be circulating and go from there.
