Speed Queen Washer-Extractor Error Code E d 01: Drive Setup Error
E d 01 on a CHM1792C washer-extractor is a setup command error from the drive. The drive board received parameters from the front-end control that it could not accept, so it refused to start the motor. Power down to clear it and call us if it returns.
High: the drive refuses to start the motor, so the machine will not spin.

What does Speed Queen error code E d 01 mean?
The motor in this washer-extractor is driven by a separate drive board. Before it starts the motor, the front-end control sends it a set of setup parameters, much like a list of instructions for how to run. The drive checks them. If any are outside what it can use, the drive refuses to start rather than run the motor with wrong values, and the display shows E d 01 (display text: E d 01). The machine stops before spinning. The owner's manual says that powering the machine down clears it, and that a technician should be called if it comes back. The possibilities include drive board settings that do not suit this machine's setup, a weak link between the front-end control and the drive, and a recently replaced board that carries the wrong parameters. The last one is a clue worth passing on if a board was changed recently. A cycle with a normal load after the power-down shows whether it was a one-time event.

How a technician diagnoses error code E d 01
- Read E d 01 and ask whether a board was recently replaced.
- Confirm the drive and front-end control parts match this model.
- Check the communication cable between the two boards.
- Review the drive parameter set against the machine's model data.
- Reload or replace the drive board only after the cable and parameters are confirmed.
- Drive parameters are specific to the machine and must be set with the machine's own data.
- The drive board sits at 208-240 V and holds charge after power is removed.
- A wrongly set drive can damage the motor.
