| Dishwasher appears to have something in the impeller chamber I have a Kenmore model 665 dishwasher. When running it sounds (a grinding noise) as though there is something in the impeller . Can I get to the impeller from inside the dishwasher by removing the lower sprayer arm and subsequently the strainer etc. and get to the impeller) If so ,,, there appears to be a large threaded plastic thumb screw (that doesn't want to turn by hand or with use of plyers - I didn't put too much pressure on it for fear of breaking it) that is holding the lower spray arm in place .... |
