Speed Queen Washer-Extractor Error Code E d 22: Motor Over Temperature

What does Speed Queen error code E d 22 mean?

Inside the motor is a temperature reading that the drive follows. A motor that works too hard heats up, and heat is what damages windings. When the reading goes above the limit, the drive stops the motor before harm is done, and the display shows E d 22 (display text: E d 22). The washer-extractor then waits for the motor to cool and for power to be cycled. The manual lists a drum that does not turn freely so the motor strains, a load too heavy for the machine, a motor harness connection that is loose or damaged, and a motor that has worn and runs hot. A heavy overload is the cause the owner can do something about. The code is not about the washing water or the door. The owner's manual clears it with a power-down. If the code returns on a normal load, the motor or the drum is the likely cause, since a free-turning drum with a sensible load should not overheat the motor.

Affected models and control systems

Speed Queen CHM1792C family washer-extractors (QN models, 20-100 lb) with the front-end control. Other washer-extractor families, such as CHM495R, list different codes.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

What you may notice

• E d 22 on the display
• The motor stops during spin or after a heavy load
• The motor housing feels hot afterward

Possible causes

Listed in Speed Queen's documentation

• Drum that does not turn freely so the motor strains
• Load too heavy for the washer-extractor
• Motor harness connection loose or damaged
• Motor worn and running hot

Other likely causes — what usually sits behind error code E d 22 on this control. A technician confirms which one it is before any part is replaced.

• A bearing starting to drag after years of heavy linen loads
• Lint and dust blocking the motor cooling vents

Safe checks before calling for service

How a technician diagnoses error code E d 22

1. Read E d 22 and check the load size and cycle history.
2. Turn the basket by hand with power locked out to feel for drag.
3. Check the motor vents and cooling airflow.
4. Inspect the motor harness plugs and wires for heat damage.
5. Test motor winding resistance, and replace the motor only if the test fails.

How error code E d 22 differs from similar codes

E d 22 concerns motor temperature; E d 25 concerns the drive's power module temperature.
