I have a FDB1500LFS2
dishwasher which has not been adequetly pumping water during wash cycles. At first I thought it was a loading issue, but after a few retries the pump too on a "choppy" sound. Upon further investigation, I found that the circulator motor was not operating correctly. After cleaning out the sump area and checking the impeller (spins freely, no obstructions) the issues persisted. Playing with it further, I found that simply pulling toward the front of the dishwasher on the black plastic motor housing the pump would operate correctly. When pressure is released it feels as if the part of the pump is hitting the housing and the pump goes back to not working.
Any ideas what might be causing this? (bent shaft?)Is it possible that the pump unit could be repaired? Is replacement the only option?
Thanks for the help!
