What affects the repair cost
A clogged filter or spray arm is a cleaning job. A heating element, wash pump or drain pump is a part plus labour, and the dishwasher usually has to come out from under the counter for the element. Ask whether the diagnostic fee is credited if you go ahead.

Common questions
How often should I descale a dishwasher on San Antonio water?
Follow the manual; in very hard water many owners descale every one to three months. Persistent film between cleanings suggests the hardness setting or rinse aid needs adjusting.
