My white- westinghouse dishwasher, made by fridgidaire, model # Su550axr1 , overflows between door and bottom compartment when I turn it on to wash dishes. This appliance was the new condo I recently bought. No mention of a problem with the appliance was recorded in the contract of sale. One thought, the pipe leading away from the dishwasher is clogged and water has no outlet for used water to be fed away from the dishwasher. I do not have the manual. Does anyone have the manual or a fix it idea?
