Water temperature sensor shorted

Locate the thermistor in the sump area and disconnect its leads
Measure resistance — a shorted sensor reads near 0 ohms instead of ~55,000 ohms at room temp
Inspect the wiring for damaged insulation or bare wires contacting the metal sump housing
Check the connector for signs of moisture intrusion or corrosion creating a short path
Pro Diagnostic Tip
A shorted thermistor sends a false high-temperature signal, causing the dishwasher to skip the water heating phase. On KitchenAid models, dishes may come out with greasy residue because the water never reached sanitizing temperature. The combined OWI/thermistor assembly is a single replaceable unit.
