GE Dishwasher Error Code E6 — What It Means & How to Fix It

What Does This Error Mean?

E6 on a GE dishwasher means the water temperature sensor has an open circuit. The sensor wire or probe has broken completely, so no temperature reading reaches the control board. The dishwasher cannot verify water temperature and stops the cycle.

Affected Models

GE Built-In Dishwasher
GE Profile Dishwasher
GE Top Control Dishwasher
GE Stainless Steel Dishwasher

Common Causes

The NTC thermistor (temperature sensor) wire has broken, creating an open circuit
The sensor probe has physically cracked or separated from its housing
A connector pin has pulled out of the wiring harness between the sensor and the control board
Corrosion on the sensor connector has completely interrupted the electrical circuit
The control board itself has failed and is reading the sensor as open

How to Fix It

Turn off the dishwasher at the circuit breaker for 5 minutes, then restore power and run a test cycle.

A transient control board fault can mimic E6. A full power reset clears it if no real sensor failure is present.
Check your home's hot water supply. Run the kitchen tap until fully hot before starting a wash cycle.

If the incoming water is very cold, some models can initially read the sensor as open until the water warms up.
Unplug the dishwasher and locate the thermistor — a small probe near the heating element at the base of the tub. Inspect the wire harness connector and reseat it firmly.

An open circuit is often caused by a connector that has partially pulled out rather than a broken sensor.
Inspect the full length of the thermistor wire from the probe to the connector for any visible damage — cuts, kinks, or burn marks.

The wiring runs along the base of the tub and can be pinched if the dishwasher was recently serviced or moved.
If E6 returns after reconnecting wires, test the thermistor with a multimeter. A working sensor shows resistance. An open reading (OL or infinite) means the sensor has failed and needs replacing.

GE thermistors typically cost $15 to $35. Order by your model number (label inside the door frame).

When to Call a Professional

If resetting and checking wire connections does not resolve E6, the thermistor needs to be tested with a multimeter. An open reading (infinite resistance) confirms the sensor has failed and must be replaced. A technician can test and replace the thermistor for $80 to $150 including parts and labor.

Frequently Asked Questions

What is the difference between E6 and E7 on a GE dishwasher?

Both codes involve the water temperature sensor. E6 means the sensor circuit is open (broken wire or failed probe). E7 means the sensor circuit is shorted (wires touching, giving a false low-resistance reading).

Can I replace the GE dishwasher thermistor myself?

Yes — it is a straightforward repair. The thermistor clips or screws into the base of the tub near the heating element. Order the part by your model number and use basic tools — no special training needed.

Will E6 damage my dishwasher if I ignore it?

The dishwasher will not run a full cycle with E6 active. Ignoring it just means dirty dishes — it does not cause further damage. But fix it before relying on the machine for regular use.
