Speed Queen Washer: Troubleshooting a Detergent... | appliancefaults.com

Technical Background:

The Speed Queen washer's detergent dispenser system relies on a series of timed water fills and siphon action or a dedicated pump to flush detergent into the wash drum at specific points in the cycle. The Main Control Unit (MCU) controls water valve solenoids that direct water to the dispenser. If the dispenser drain is blocked, the siphon is not working properly, or the water valves are malfunctioning, the dispenser will retain water. Voltage to the water valve solenoids is typically 120V AC.

Symptoms:

The homeowner observes that after each wash cycle, the detergent dispenser drawer in their Speed Queen washer is still holding a significant amount of water. This water may be clean or slightly soapy, depending on the cycle. The dispenser may not be draining completely, or it may be filling up with water during the cycle and not emptying properly.

Possible Causes:

Clogged or partially obstructed dispenser drain port.
Siphon issue within the dispenser (if applicable to the model).
Low water pressure affecting the siphon action.
Malfunctioning water inlet valve not fully closing, allowing continuous slow fill.
Debris or lint buildup in the dispenser housing or water channels.
Incorrect leveling of the washing machine, affecting drainage.

Solution:

1

Turn off the washer and unplug it from the outlet.
2

Turn off the water supply valves to the washer hoses.
3

Remove the detergent dispenser drawer completely. Inspect the drawer and housing for any visible clogs or debris. Clean thoroughly with warm water and a mild detergent.
4

Inspect the dispenser drain port at the rear of the dispenser housing. Use a small brush or pipe cleaner to remove any blockages. A small wet/dry vacuum can also be used to extract debris.
5

Check the water inlet valve solenoids. With the washer unplugged, use a multimeter to test the resistance of each solenoid. A typical reading is between 800 and 1500 ohms. An open or shorted solenoid indicates a faulty valve. Replace as needed.
6

Level the washing machine using a bubble level. Adjust the leveling feet to ensure the machine is sitting evenly on the floor. This can improve drainage.
7

Reconnect the water supply hoses, plug in the washer, and run a test cycle (rinse/spin) to verify that the dispenser drains correctly.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Verify the absence of voltage with a multimeter before touching any electrical components. Water and electricity pose a shock hazard. Always turn off the breaker at the breaker panel prior to working on the appliance (Lock Out Tag Out - LOTO).

Prevention:

Regularly clean the detergent dispenser drawer and housing every month. Run a washer cleaning cycle with a washing machine cleaner every 3 months to prevent buildup of detergent residue and mineral deposits.

Expert Tip:

Some Speed Queen washers have a diagnostic mode that allows you to test individual components, including the water inlet valves. Consult the service manual for your specific model to access this mode and run a water valve test. Also, using too much detergent can cause buildup and drainage issues; use the recommended amount only.

Frequently Asked Questions

•How do I access the diagnostic mode on my Speed Queen washer to test the water inlet valves?

The diagnostic mode entry procedure varies depending on the specific model. Consult your service manual or search online using your model number and 'diagnostic mode' to find the correct sequence of button presses.

•What is the correct water pressure for my Speed Queen washer to ensure proper dispenser drainage?

Speed Queen washers typically require a water pressure between 20 and 100 PSI. Check your home's water pressure using a pressure gauge attached to an outdoor faucet. If the pressure is too low, consult a plumber.

•Where can I find replacement water inlet valves for my Speed Queen washer?

Replacement water inlet valves can be purchased from appliance parts retailers online, local appliance parts stores, or directly from Speed Queen. Make sure to have your model number handy to ensure you order the correct part.
