GE dishwasher error codes can be confusing — and the meaning varies by model year. Here's what the most common ones mean in practice.
E1 Error — Leak / Flood Protection
On most GE models, E1 indicates the anti-flood protection (leak sensor) has been triggered. Water has been detected in the base pan of the dishwasher. Causes:
- •Door gasket failure
- •Pump or hose connection leak inside the unit
- •Overfilling (water inlet valve staying open too long)
To reset: turn off and unplug the dishwasher. Tilt the unit slightly to drain any water from the base pan (towels underneath). If the error clears, find the leak source before resuming use. If the error recurs immediately, the leak is active.
E3 Error — Water Heating Issue
On GE models where E3 appears, it typically indicates the water isn't reaching temperature within the expected time. Causes:
- •Water supply temperature too low (ensure the supply line connects to hot water)
- •Heating element failure
- •Temperature sensor failure
Quick check: Run the kitchen hot water tap until it's hot before starting the dishwasher — this ensures hot water is in the supply line at cycle start, reducing the initial heating demand.
Repair costs: - Heating element replacement: $150–260 - Temperature sensor replacement: $100–170
Other GE Codes
- •C1: Sensor fault (service call needed)
- •C3 / C7: Thermistor or temperature sensor failure
- •PF: Power failure — simply restart the cycle

GE Dishwasher E1 Error in Houston: Diagnosis and Repair
The E1 error code on a GE dishwasher indicates a thermistor (temperature sensor) failure or a water temperature issue. Houston's water supply enters dishwashers at 60 to 75 degrees F depending on the season, and E1 can appear when the dishwasher fails to heat the water to the target temperature within the expected time. Here is what the E1 error means and how to resolve it.
What the GE Dishwasher E1 Error Means
GE dishwashers display E1 when the control board detects that the wash water has not reached the target temperature (typically 120 to 140 degrees F) within the programmed time. This can mean the water entering the dishwasher is too cold (below 120 degrees F at the inlet), the heating element inside the dishwasher has failed, or the thermistor that monitors water temperature is reading inaccurately. Before assuming a component failure, check your home's water heater temperature setting — it should be set to 120 degrees F minimum for dishwasher performance. If the water heater is set correctly and the E1 persists, a component requires testing.
Diagnosing E1: Heating Element vs. Thermistor
The heating element and thermistor are both testable with a multimeter. The heating element should show approximately 10 to 20 ohms resistance (varies by model). An open circuit (infinite resistance) means the element has failed. The thermistor should show resistance that changes with water temperature — a fixed resistance reading regardless of temperature means the thermistor has failed. We test both components on every GE dishwasher E1 call before recommending replacement. Heating element replacement: $30 to $70 for the part. Thermistor replacement: $20 to $40 for the part.
