Frigidaire Dishwasher Error Code i61

The i61 code means the dishwasher detected water temperature above 78°C during a wash cycle and stopped operation to prevent damage. This is a heating over-temperature fault triggered by the control board when the temperature sensor reports a value beyond the safe threshold. It can result from a malfunctioning heating element, a faulty temperature sensor, or wiring problems in the heater circuit.

No, you should not continue running the dishwasher while the i61 code is active. The fault indicates the water heating system is behaving abnormally, and continued use could result in further damage to internal components or create an unsafe condition. The dishwasher stops the cycle automatically for this reason, and the issue should be diagnosed before resuming normal use.

Repair costs vary depending on which component has failed. A replacement NTC thermistor is typically a lower-cost part, while a new heating element or control board will cost more, generally ranging from $80 to $250 or higher for parts alone. Adding professional labor, total repair costs can range from $150 to $400 depending on the fault and your location.

Some causes of the i61 error are DIY-accessible, such as inspecting and reseating wiring harness connections or testing the NTC thermistor with a multimeter. However, replacing the heating element, control board, or temperature sensor requires comfort working with electrical components and disassembling the dishwasher interior. If you are not confident working with appliance wiring, a qualified technician is the safer choice.

A reset may clear the displayed code temporarily, but the fault will return if the underlying cause is not repaired. The i61 code is triggered by an active condition: water temperature exceeding 78°C or a sensor reporting that it has. Until the defective component is identified and corrected, the dishwasher will stop the cycle and display the error again.
