Electrolux Dishwasher Error Code F1

F1 on an Electrolux dishwasher signals a temperature stop fault. The dishwasher monitors water temperature during the heating stage and requires at least a 5°C rise within ten minutes. When that rise is not detected, the control unit logs F1, exits the heating stage, and continues the programme without reaching the target temperature. This typically points to a problem with the heating element, thermistor, water fill level, circulation pump, or related wiring.

When F1 is active, the dishwasher completes the cycle without reaching the correct wash temperature, meaning dishes may not be properly cleaned or sanitized. It is not a fire or flood hazard in most cases, but continuing to run the machine without addressing the fault means cycles will be ineffective. It is best to diagnose and resolve the issue before relying on the appliance for regular use.

A reset may clear the F1 code temporarily, allowing the dishwasher to start a new cycle. However, if the underlying fault with the heating element, thermistor, water level, pump, or wiring is not corrected, the error will return during the next heating stage. Resetting is useful for confirming the fault is repeatable, but it is not a fix and should be followed by a proper diagnosis.

Some causes of F1 are accessible to a confident DIYer. You can check the water fill level, inspect wiring connections for obvious corrosion or looseness, and test the heating element for continuity with a multimeter. Replacing the heating element or thermistor is also a manageable repair if you are comfortable working with appliance components. However, if the circulation pump or control unit is the source of the fault, a qualified technician is recommended.

Repair costs depend on the faulty component. A replacement heating element typically costs between $20 and $60 for the part, while a thermistor is generally in the $10 to $30 range. If you hire a technician, labour charges are additional and vary by region. A circulation pump or control unit replacement will be significantly more expensive, potentially ranging from $100 to $300 or more including parts and labour.
