Detergent Valve Pin HW On/Off Fail Error (E d 49 or Ed, 49)

• Detergent Dispenser Valve Malfunction: The error code suggests a problem with the hardware components responsible for opening and closing the valve that dispenses detergent during the wash cycle. This could be due to:
  • Faulty Solenoid: The solenoid, an electrically controlled valve, might be malfunctioning and unable to open or close the dispenser valve properly.
  • Clogged Valve: The valve itself might be clogged with detergent residue or debris, preventing it from opening or closing completely.
  • Wiring Issues: Electrical wiring connections between the control board and the detergent valve solenoid could be loose, damaged, or corroded.

Troubleshooting Steps

Important Note: While the following steps might resolve the issue, some involve electrical components and accessing the washer's interior. Proceed with caution and only if you are comfortable:

1. Unplug the Washer: Before attempting any troubleshooting, ensure the washer is unplugged from the power outlet to prevent electrical hazards.
2. Consult the Manual: Refer to your Speed Queen washer's user manual for specific instructions on cleaning and maintaining the detergent dispenser drawer. It might also have troubleshooting steps related to the detergent valve.
3. Clean the Dispenser Drawer: Clean the detergent dispenser drawer thoroughly with warm water and a mild detergent. Look for any blockages or debris that might be preventing the valve from functioning correctly.

Beyond cleaning the dispenser drawer, further user troubleshooting steps are limited due to the potential for electrical components and the need for internal access.

If the Error Persists

• Contact Speed Queen Support: Since the error code points towards a hardware issue with the detergent valve control, contacting Speed Queen's customer support is recommended.They can provide further guidance and determine if the issue requires a qualified technician's expertise.
• Contact a Qualified Technician: Given the potential for electrical components involved with the detergent valve control, consulting a qualified appliance repair technician is recommended. They can diagnose the problem accurately (faulty solenoid, clogged valve, wiring issues) and recommend the appropriate solution (cleaning, repair, or replacement of the necessary components).

Safety Considerations:

• Avoid Electrical Work: Diagnosing and repairing detergent valve control issues might involve electrical components. Leave these tasks to a qualified technician.
• Do Not Use Harsh Chemicals: Avoid using harsh chemicals or abrasive objects to clean the detergent dispenser, as they can damage the components.

By following these steps and prioritizing safety, you can potentially address a clogged detergent dispenser causing the E d 49 or Ed, 49 error on your Speed Queen washer. However, for a proper diagnosis and repair of the detergent valve control system, consulting a qualified technician is the best course of action, especially if the issue persists after cleaning or involves electrical components.
