Maytag Washer Error Code 17

Error code 17 means the control board detected a possible short circuit in the thermistor, which is the temperature sensor used to monitor water temperature during the wash cycle. When the thermistor shorts, its resistance reading drops abnormally low, triggering the fault. The code points to the thermistor itself, its wiring harness, or its connector as the most likely source of the problem.

Running the washer with code 17 active is not advisable for cycles that depend on water temperature control, such as hot or warm wash cycles, because the control board cannot accurately monitor temperature. Using the washer in this condition risks improper washing results and may cause the board to interrupt cycles mid-wash. It is best to diagnose and resolve the thermistor short before continuing regular use.

Yes, testing the thermistor is a practical DIY step. Unplug the washer, access the thermistor for your specific model, disconnect the harness connector, and set a multimeter to measure resistance in ohms. A healthy thermistor will show a specific resistance value at room temperature as listed in your model's technical sheet, typically several thousand ohms. A reading of zero or near zero confirms a short and means the thermistor needs replacement. If the reading is within spec, move on to inspecting the wiring harness and connector for damage.

Start by unplugging the washer and locating the thermistor, then disconnect its wiring harness and use a multimeter to measure the thermistor's resistance. A shorted thermistor will read near zero ohms rather than the expected resistance range listed in your model's service manual. If the thermistor reads shorted, replace it. If it reads correctly, inspect the wiring harness for pinches, chafing, or melted insulation and replace any damaged sections. If both components check out, the control board may need replacement.

If the thermistor is the failed component, the part typically costs between $15 and $40 depending on your model, and replacing it is a moderate DIY repair requiring basic tools and a multimeter. If the wiring harness is damaged, a replacement harness runs $20 to $60. A control board replacement is the most expensive outcome, with parts ranging from $100 to $250 or more plus labor if you hire a technician. Professional diagnosis and repair labor typically adds $75 to $150 on top of parts costs.
