The error code E SH or Er, SH on your Speed Queen washer indicates a Shorted Temperature Sensor Error. This means the washer's control board detects a malfunction within the thermistor, the sensor responsible for monitoring water temperature during wash cycles. Unlike an Open Temperature Sensor Error (E oP), a Shorted Sensor indicates a different kind of electrical issue.
Here's a breakdown of the issue, potential causes, and why consulting a qualified technician is recommended
Possible Causes of Shorted Temperature Sensor Error (E SH or Er, SH):
The control board is detecting an abnormal electrical reading from the thermistor. This suggests a short circuit within the sensor itself or its wiring. Here are some possible causes:
- Faulty Thermistor: The thermistor might be internally damaged, causing a short circuit.
- Damaged Wiring: The wiring harness connecting the thermistor could be damaged or frayed, leading to a short circuit between wires.
- Water Damage (Less Likely): In rare cases, water damage to the thermistor or its connection could cause a short circuit.
Important Considerations:
- Limited User Repair: Diagnosing and repairing thermistor shorts or damaged wiring often involve technical knowledge and potential electrical components. It's best to avoid attempting a DIY repair.
- Safety and Functionality: A Shorted Temperature Sensor Error can disrupt the washer's ability to regulate water temperature properly, potentially leading to issues like overheating or using incorrect water temperatures for the wash cycle.
- Consult a Technician: If you see the E SH or Er, SH error code, contacting a qualified appliance repair technician is highly recommended. They can diagnose the issue (faulty thermistor, damaged wiring, or water damage) and recommend the appropriate solution.
Potential Solutions
- Replacing the Thermistor: In most cases, the technician will likely replace the thermistor if it's faulty and causing the short circuit.
- Repairing or Replacing Wiring: If the wiring harness is damaged and causing the short, the technician can repair it or replace it entirely.
- Addressing Water Damage (Less Likely): In rare cases of water damage, the technician will assess the extent of the issue and determine the necessary repairs.
Safety Reminder: Remember, Shorted Temperature Sensor Errors involve potential electrical issues. Leave the diagnosis and repair to a qualified appliance repair technician to ensure safety and proper repairs. Don't attempt to use the washer with this error until the problem is resolved.
