Speed Queen Washer Lid Lock Flashing: Troubleshooting &... | appliancefaults.com

Technical Background:

The washer's Main Control Unit (MCU) monitors the lid switch and the lid lock solenoid. When the start button is pressed, the MCU checks the lid switch status. If the lid switch indicates the lid is closed, the MCU energizes the lid lock solenoid, locking the lid. The MCU then verifies that the lid is locked via a feedback signal from the lock assembly. If this process fails at any stage, the MCU will prevent the wash cycle from starting and trigger the flashing lid lock indicator. This logic is designed to prevent operation with the lid open, ensuring user safety. Voltage to the lock is typically 120V AC.

Symptoms:

The homeowner observes that the Speed Queen washer's lid lock light is flashing and the machine will not start a wash cycle. The lid appears to be closed, but the washer remains unresponsive. Attempts to start the cycle are unsuccessful.

Possible Causes:

Lid switch failure.
Control board malfunction.
Wiring harness issue between the lid switch and the control board.
Obstruction preventing the lid from fully closing.
Faulty lid lock solenoid.
Voltage supply issue to the lid lock circuit.

Solution:

1

Unplug the washer from the outlet.
2

Inspect the lid switch for physical damage or obstruction. Clean any debris.
3

Using a multimeter, check the continuity of the lid switch when the lid is closed. It should show continuity (close to 0 ohms). Replace if open.
4

Check the wiring harness between the lid switch and the control board for any breaks or loose connections.
5

Locate the lid lock solenoid. With the washer plugged in (carefully), use a multimeter to check for 120V AC to the solenoid when the washer attempts to start.
6

If voltage is present but the solenoid isn't engaging, the solenoid is likely faulty. Replace the lid lock assembly.
7

If there is no voltage, suspect a faulty control board. Replace the control board.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. High voltage is present in the washer's electrical components. Use extreme caution when working with electricity. Lock Out/Tag Out (LOTO) procedures should be followed.

Prevention:

Periodically check the lid switch and surrounding area for any debris buildup. Ensure the lid closes smoothly and completely. Avoid slamming the lid, as this can damage the lid switch or locking mechanism.

Expert Tip:

On some Speed Queen models, entering the service mode allows you to manually activate the lid lock solenoid for testing purposes. Refer to the service manual for the specific sequence for your model. This usually involves pressing a specific combination of buttons on the control panel.

Frequently Asked Questions

•How do I access the lid switch on my Speed Queen washer?

Accessing the lid switch typically involves removing the top panel of the washer. This often requires removing screws located at the back of the washer. Once the screws are removed, the top panel can usually be slid back and lifted off. The lid switch will then be visible and accessible.

•Where can I find the service manual for my specific Speed Queen washer model?

You can often find service manuals on the Speed Queen website under the 'Support' or 'Resources' section. Alternatively, websites like AppliancePartsPros or RepairClinic may have service manuals available for download after entering your model number. Local appliance parts suppliers may also carry service manuals.

•What type of multimeter is recommended for testing the lid switch and solenoid?

A basic digital multimeter (DMM) capable of measuring AC voltage, DC voltage, and resistance (ohms) is sufficient. Ensure the multimeter has a continuity testing function, often indicated by a diode symbol or audible beep. A multimeter with automatic ranging is helpful but not required. A model with safety certifications (UL, CE) is recommended.
