My dishwasher will not drain, inspected hose, check valve - no problems.
Now attempting to inspect lower impeller - but can't remove impeller screw from upper impeller.
Can't get enough of a grip on the impeller to keep the motor shaft from turning to get the screw out. The upper impeller is made out of plastic and any grip seems to strip away rather than holding it in place.
I see in some forums folks suggest breaking the upper impeller but I don't see how this will help - the screw would still be difficult to remove.
Very close to calling a technician - any assistance / suggestions would be greatly appreciated.
