Possible Causes
Defective high-level pressure switch, Blocked secondary air trap, Wiring fault to secondary level sensor, Control misinterpretation of level signals
How to Fix / Troubleshooting
Safety first: Disconnect power and water supply before servicing level sensors.
- Locate secondary sensor: Many UniMac washers use a second pressure switch for high water level. Identify this switch and its hose.
- Inspect and clear hose: Remove the hose and ensure it is free of soap residue or lint. Clean the air trap on the tub.
- Test switch: Use a multimeter to check continuity changes as you apply gentle air pressure. Replace the switch if it does not operate correctly.
- Check wiring: Verify the harness from the secondary switch to the control is intact and properly connected.
