Speed Queen Washer Error Code E2
Thermistor fault — water temperature sensor out of range
Common Causes
- 1Water temperature sensor failure
- 2Wiring to sensor damaged
- 3Connector corrosion
- 4Sensor dislodged from sump housing
Step-by-Step Troubleshooting
- 1
Locate the NTC thermistor on the outer tub sump area
- 2
Disconnect and measure resistance — should read approximately 50K ohms at room temperature
- 3
Inspect the two-pin connector for green corrosion or loose fit
- 4
Check the wiring from the thermistor to the main control board for chafing
- 5
Confirm the sensor is fully clipped into the sump housing — a dislodged probe reads ambient, not water, temperature
Pro Diagnostic Tip
Speed Queen NTC thermistors are negative-temperature-coefficient, so resistance drops as the water heats: a reading stuck at infinity means the sensor is open, while near zero means it is shorted. This is a temperature-sensing fault, distinct from the E3 heater-relay code on the same machine — the water simply is not being measured. Because these are commercial-grade units, the mechanical diagnostic is simple: reseat and clean the two-pin connector before condemning the probe.
