Affected model seriesmodern dishwasher F-code service family
Quick answer
Temperature-sensor failure.
Model compatibility: GE reuses codes across series and model years, so F50 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Temperature-sensor failure.
Signs
Symptoms you may notice
Fans or heating/cooling loads may cycle abnormally.
The code may appear after the control fails to reach or maintain a temperature target.
The code may return shortly after startup or during the affected cycle stage.
Operation may stop when the control sees an implausible reading.
Why it happens
Possible causes
A sensor or thermistor that has drifted outside its expected range.
A fan, heater, compressor-related, or relay/control problem depending on the appliance.
A blocked vent or prolonged door-opening condition.
An airflow, cooling, or heating problem that keeps temperature outside the expected range.
A control fault that mismanages temperature after the physical system is checked.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Note whether the code appears immediately or only after heating/cooling begins; that timing is useful for diagnosis.
Power the appliance off once and allow it to restart normally if there is no leak, overheating, or electrical damage.
Allow for recovery after a large warm load or long door opening before judging a one-time temperature event.
Confirm doors/lids close fully and that user-accessible vents are not blocked.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
