Hot-water thermistor out of range.
Model compatibility: GE reuses codes across series and model years, so 0513 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
Hot-water thermistor out of range.
Signs
Symptoms you may notice
Other components may be disabled because the control cannot trust the sensor input.
The code may return shortly after startup or during the affected cycle stage.
Temperature-related performance can become inconsistent.
The tank may fail to fill, heat, purge, or dispense as expected.
Why it happens
Possible causes
Wiring damage between the sensor and the main control.
An open, shorted, corroded, or loose sensor connection.
A door-board or main-control fault after the water/heater circuit is verified.
A tank heater, temperature/pressure switch, or thermistor problem where applicable.
A sensor or thermistor that has drifted outside its expected range.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Do not disconnect internal sensors just to “test” whether the code clears; that can create additional faults.
Note whether the code appears immediately or only after heating/cooling begins; that timing is useful for diagnosis.
Do not open the door/tank heater circuit or bypass temperature/pressure protection as a consumer test.
Use the hot-water function only if there is no leak or abnormal temperature behavior.
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.
