LG Washer Error Code E-26

The E-26 code means the water temperature did not rise above a required threshold within the first 3 minutes of the heating cycle. The washer's control board monitors temperature through a sensor and expects to see a minimum rate of temperature increase once the heater activates. When that increase does not occur in time, the fault is triggered. The most likely causes are a failed heating element or a defective temperature sensor.

It is not recommended to continue running wash cycles while this error is active. The washer has detected a heating system failure, which means heated wash programs will not perform correctly. Continuing to run cycles could also mask a wiring or component issue that might worsen over time. Address the fault before resuming normal use.

A reset may temporarily clear the error code from the display, but if the underlying cause is not repaired, the fault will return as soon as the washer attempts a heated wash cycle again. To permanently resolve E-26, the faulty component, whether the heater, sensor, or wiring, must be identified and corrected. A reset is useful for confirming whether the issue is intermittent, but it is not a fix.

A knowledgeable DIYer can diagnose this error by testing the temperature sensor and heating element with a multimeter for proper resistance and continuity. Wiring connections should also be visually inspected for damage. If either component tests as faulty, replacing it is a moderate-difficulty repair. However, working near the heater circuit involves electrical components, so the washer should always be unplugged before any inspection or repair.

Repair costs depend on which component has failed. A replacement heating element typically costs between $20 and $80 for the part, while a new temperature sensor generally ranges from $10 to $40. If professional labor is involved, total repair costs including parts and service can range from $100 to $250 or more depending on your location and the technician's rates.
