Jenn-Air JDTSS244GP 24 in Top Control Built-In Dishwasher with 42 dBA, Third Rack, and Sensor Wash F1E1 Error Fix: Temperature Sensor Failure

Error code F1E1 on the Jenn-Air JDTSS244GP 24 in Top Control Built-In Dishwasher with 42 dBA, Third Rack, and Sensor Wash means: Temperature Sensor Failure. The water temperature sensor (thermistor/NTC) has failed or is reading out of range — the sensor should read approximately 50K ohms at 77°F (25°C) and its resistance changes predictably with temperature; check the sensor wiring and connector on the main control board; if the wiring is intact, replace the temperature sensor; an out-of-range sensor prevents the dishwasher from properly regulating water temperature for wash and sanitize cycles
