Maytag Washer Error Code E15

E15 on a Maytag washer means the water temperature inside the machine is 15°C (59°F) above the target temperature set for the selected cycle. The control board monitors water temperature throughout the wash and triggers this code when it detects that level of thermal overshoot. The most immediate thing to check is whether the water inlet valves have been correctly programmed, since an incorrect valve assignment can cause hot water to enter when it should not.

The E15 code is a protective fault, meaning the washer has detected an unsafe temperature condition and is alerting you before damage can occur. Extremely hot water can damage delicate fabrics and potentially stress internal hoses, seals, and plastic components. Running the machine repeatedly while this fault is active is not recommended until the root cause has been identified and corrected.

A power reset may temporarily clear the E15 code, but the fault will return if the underlying cause has not been addressed. Since this error reflects an actual measured temperature condition rather than a simple communication glitch, the root cause such as incorrect valve programming, a stuck inlet valve, or a faulty sensor must be corrected for the code to stay cleared. Always diagnose and repair the cause before assuming a reset has resolved the issue.

Start by confirming that the hot and cold water inlet valves are correctly programmed in the control settings, as an incorrect assignment is a leading cause of this error. Next, inspect the hot water inlet valve itself to ensure it closes fully and is not stuck open. Also check the cold water supply line for restrictions, and test the thermistor if valve and supply checks come back normal.

If the fix is simply a valve programming correction, there may be no parts cost at all, though a service call fee typically ranges from $75 to $150. Replacing a faulty hot water inlet valve generally costs between $40 and $120 for the part, plus labor. A thermistor or temperature sensor replacement usually falls in the $20 to $60 range for the part itself.
