AEG Washer Error Code E70

E70 on an AEG washer indicates a fault in the heating circuit, meaning the machine detected that the water was not being heated correctly. The most common causes are a defective NTC temperature sensor, a failed heating element, or a broken wiring connection in the heater circuit. The washer uses the NTC to monitor water temperature, and if that signal is missing or incorrect, the fault is logged. The machine will not complete heated wash programs until the issue is resolved.

You should avoid running heated wash cycles when E70 is active, as the machine cannot confirm proper heating, and laundry may not be cleaned or sanitized effectively. Cold wash programs may still run, but the underlying fault should be diagnosed and repaired promptly. Continuing to run the machine without addressing the fault could allow a wiring or component issue to worsen over time.

A power reset may temporarily clear the E70 code, but it will return as soon as the washer attempts a heated cycle and encounters the same fault condition again. The error will persist until the defective component, whether the NTC sensor, heating element, or wiring connection, is actually repaired or replaced. Resetting without repairing is not a solution and the washer will continue to fail heated wash programs.

Replacing the NTC sensor is a relatively accessible repair for a technically confident DIYer, as it typically involves removing the back panel and disconnecting a small plug-in sensor near the heating element. Testing and replacing the heating element requires working safely with mains-voltage components and using a multimeter for continuity checks. If you are not comfortable with electrical testing or working inside appliances, a qualified technician should perform the repair.

If only the NTC sensor needs replacement, parts and labor costs are typically in the range of $50 to $150 depending on your region and whether you do the repair yourself. If the heating element has failed, total repair costs including parts and labor generally range from $150 to $350. Wiring repairs vary depending on the complexity of the damage found.
