Speed Queen Washer-Extractor Error Code E d 29: Motor Not Connected
E d 29 on a CHM1792C washer-extractor means the drive does not see the motor connected. The motor harness may be unplugged at either end. The machine stops, so switch power off to clear the code and call us for service.
High: the drive will not run without a motor connection, so the machine cannot spin.

What does Speed Queen error code E d 29 mean?
Before it turns the motor, the drive checks that a motor is actually connected to its output. It does this by sensing the electrical load on the three motor leads. If it finds no load, it assumes the motor harness is unplugged or broken, and it will not drive anything, since sending power to open wires is pointless and risky. The display shows E d 29 (display text: E d 29), and the machine stops. The owner's manual tells a technician to confirm that the motor harness is seated at both ends and to switch power off to clear the code. It lists a harness unplugged at the motor end, a harness loose at the drive end, a wire cut or chafed along its run, and open motor windings that the drive cannot sense. Vibration over the years can work a plug loose or wear a wire at a bracket. The code is about the motor connection, not the load or the door.

Safe checks before calling for service
- The owner's manual says powering down clears this code, so shut the machine off.
- Wait for the door lock to release before opening.
- Plugs inside the cabinet are not for owners to check.
- If the code returns, call us to schedule a visit.
How a technician diagnoses error code E d 29
- Read E d 29 and confirm no motor movement at all.
- With power locked out and the drive discharged, inspect the harness plug at both ends.
- Check continuity of each motor lead along the full run.
- Measure winding resistance between phases.
- Repair the harness or replace the motor only after the readings.
- The drive can hold charge at 208-240 V, so connectors cannot be handled without discharging it.
- A cut motor lead may hide inside a harness bundle and need tracing.
- An open winding can look the same as a loose plug, and only a meter separates them.
How error code E d 29 differs from similar codes
E d 29 is no motor detected; E d 34 is a motor that is connected but locked.

Related Speed Queen washer error codes
Is E d 29 the same as a motor failure?
Not always. A loose plug gives the same code as an open winding.
Will a restart help?
It clears the display, but a loose or cut harness will bring the code back.
Can I plug the harness back myself?
No. The plugs are inside the cabinet near live voltage.
