The error code E oP or Er, oP on your Speed Queen washer indicates an Open Temperature Sensor Error. This means the washer's control board detects a problem with the thermistor, which is the sensor responsible for monitoring water temperature during wash cycles.
Here's a breakdown of the issue, potential causes, troubleshooting steps you can try (with caution), and when to consult a qualified technician
Possible Causes of Open Temperature Sensor Error (E oP or Er, oP)
The control board cannot detect a proper signal from the thermistor. This could be due to several reasons:
- Faulty Thermistor: The thermistor itself might be malfunctioning and unable to sense water temperature accurately.
- Loose Connections: Electrical wiring connections between the thermistor and the control board might be loose or damaged.
- Damaged Wiring: The wiring harness connecting the thermistor could be damaged or frayed.
Troubleshooting Steps
Important Note: While the following steps might resolve the issue, some involve potential electrical components. Proceed with caution and only if you are comfortable:
- Unplug the Washer: Before attempting any troubleshooting, ensure the washer is unplugged for safety reasons.
- Consult the Manual: Refer to your Speed Queen washer's user manual for specific instructions on locating the thermistor (usually near the washbasket) and any recommended user-level troubleshooting steps.
- Inspect the Thermistor (if accessible): If your manual allows, visually inspect the thermistor for any visible damage or corrosion on its surface.
If the Problem Persists or You're Not Comfortable:
- Contact Speed Queen Support: Since the issue likely involves the thermistor or its connection, contacting Speed Queen's customer support is recommended: They can provide further guidance and determine if the issue requires a qualified technician's expertise.
- Qualified Technician: In most cases, a qualified appliance repair technician is recommended. They can diagnose the problem (faulty thermistor, loose connections, damaged wiring) and recommend the appropriate solution.
Potential Solutions
- Replacing the Thermistor: If the thermistor is faulty, the technician will likely replace it.
- Securing Connections: Loose connections between the thermistor and control board can be secured by the technician.
- Repairing or Replacing Wiring: If the wiring harness is damaged, the technician can repair it or replace it entirely.
Safety Considerations:
- Limited User Repair: While some initial inspection might be possible, avoid disassembling components or handling electrical wiring unless your manual provides specific instructions and you are comfortable doing so.
- Professional Help for Repairs: Diagnosing and repairing thermistor issues or wiring problems often involve technical knowledge. Leave these repairs to a qualified technician.
By following these steps and prioritizing safety, you should be able to resolve the E oP or Er, oP error on your Speed Queen washer. If you're not comfortable troubleshooting or the problem persists, don't hesitate to seek help from a qualified technician.
