- Consult your machine’s user manual or control panel error code section to confirm whether "E12" is recognized on your specific model.

- Check that water inlet hoses are not kinked or blocked.
- Clean screens on the inlet hoses and at the mixing valve if accessible.
- Restart the machine and check if any standard Speed Queen error code appears.

- Connect service diagnostic tool or enter the service mode (if available) to confirm the root error code.
- Inspect wiring and connectors between the control board and water fill components (pressure switch, inlet valves).
- Test the pressure switch and inlet valves for proper operation under load.
- Replace defective parts as needed and verify that the control board correctly interprets standard error codes.
Parts needed: Pressure switch, Water inlet valves, Control board wiring harness
