Electrolux Washer Error Code 66

Error code 66 on a Electrolux washer indicates a heater relay problem, present on select models. The control board has detected an issue with the relay that switches power to the water heating element. This fault causes the washer to stop the cycle to prevent potential overheating or damage.

It is not recommended to continue using the washer with this error active. A failed ground insulation on the heating element can create a shock hazard, and a malfunctioning heater relay could result in the element not shutting off properly. Stop using the machine until the fault has been properly diagnosed and repaired.

Repair costs vary depending on which component has failed. A replacement heating element typically ranges from $30 to $80 for the part alone. If the main control board requires replacement, parts can range from $100 to $250 or more. Adding in professional labor, total repair costs can range from $100 to $350 or higher depending on your location and the technician's rates.

Some causes, such as a loose or corroded wiring connection at the heating element, can be addressed by a knowledgeable DIYer comfortable working with appliance wiring. However, accurately diagnosing this fault requires measuring the heating element resistance with a multimeter and performing a ground insulation test, as outlined in test 14. Replacing the heating element or control board is best handled by a qualified technician.

A reset may temporarily clear the code from the display, but it will not resolve the underlying hardware fault causing the error. If the heating element resistance is out of spec, the insulation is compromised, or a relay on the control board has failed, the code will return once the washer attempts to heat water again. The root cause must be repaired to clear the fault permanently.
