KitchenAid Dishwasher Error Code WATER TEMPERATURE SENSED GREATER THAN 185°F

This error means the dishwasher's temperature sensor has detected water at or above 185°F (85°C), which is beyond the unit's safe operating range. The control board halts the cycle to prevent damage to dishes, internal components, and the appliance. Possible causes include an overly hot water supply, a continuously running heater element, a faulty thermistor, moisture near the sensor, or wiring issues in the sensor circuit.

You should not continue running the dishwasher until the cause is identified and corrected. Water exceeding 185°F can damage plastic dish racks, dishware, and internal components. If the heater element is running without shutting off, continued operation could create a more serious fault.

If the fix is simply lowering the water heater thermostat, there is no parts cost involved. A replacement thermistor typically runs in the range of $15 to $50 in parts. A defective heater element can cost $20 to $80 in parts, with professional labor adding $75 to $150 or more depending on your area and the complexity of the repair.

Start by checking your home water heater setting and lowering it if it is set above approximately 120°F. If the error persists, inspect the temperature sensor and its wiring for moisture, corrosion, or loose connections. A continuously running heater element or a failed thermistor will require component-level diagnosis and likely part replacement.

A reset may temporarily clear the error from the display, but the fault will return if the underlying cause has not been addressed. If the water supply temperature is too high or a component like the thermistor or heater element is defective, the control board will detect the problem again on the next cycle.
