Maytag Washer Error Code 1E

The 1E code on a Maytag washer indicates a sump thermistor failure. The sump thermistor is a temperature sensor in the lower sump area of the washer, and this code appears when the control board detects abnormally high or low temperature readings, or resistance values outside the expected range. The fault can be caused by a defective thermistor, loose wiring, or a damaged harness.

A reset may temporarily clear the 1E code, but if the underlying problem with the sump thermistor or its wiring has not been addressed, the code will return once the washer runs a cycle and the control board reads the faulty signal again. A permanent fix requires repairing or replacing the defective component.

If only the sump thermistor needs to be replaced, parts typically cost in the range of $15 to $50 depending on the specific model. If a professional technician is needed for diagnosis and repair, total costs including labor generally range from $100 to $200. Wiring repairs are often less expensive than part replacements, depending on the extent of the damage.

In many cases, yes. Start by unplugging the washer and inspecting the wiring harness connected to the sump thermistor for loose connectors or pinched sections. If wiring looks good, test the thermistor with a multimeter to check its resistance output. A failed thermistor is a straightforward part replacement that a confident DIYer can often complete without professional help.

It is not recommended to continue running the washer while the 1E code is active. The sump thermistor helps the control board monitor water temperature conditions, and operating without reliable sensor input could affect wash performance or allow conditions the control board cannot properly detect. Addressing the fault before continued use is the safer approach.
