Dishwasher displays i60; water may be cold or cycle may stop during heating phase.

Safety First: Disconnect power at the breaker. Heating components operate at line voltage and can be hazardous.

• Check water temperature supply: Ensure the hot water supply to the dishwasher is at least 120°F (49°C). Run the hot tap until fully hot before starting a cycle.
• Inspect heating element: On many Frigidaire Professional models, the element is hidden in the sump. Access from below and visually inspect for breaks or burn marks. Test with a multimeter for continuity; replace if open.
• Test high-limit thermostat: Locate the high-limit thermostat on or near the sump. Disconnect wires and test for continuity. If open and not resettable, replace it.
• Check temperature sensor (if equipped): Some models use an NTC sensor. Test resistance at room temperature and compare to service specs. Replace if out of range.
• Control board check: If all heating components test good, the heater relay on the main control board may have failed and the board will need replacement.
• When to call a technician: If you are not comfortable testing live voltage or replacing the control board, contact a professional technician.
