Possible Causes
Faulty pressure switch, blocked or leaking pressure hose, control board miscalibration, air dome blockage on the tub.
How to Fix / Troubleshooting
Safety first: Unplug the unit and turn off the water supply.
- Inspect pressure hose and air dome: Locate the small hose from the tub air dome to the pressure switch. Remove it and check for soap scum or debris. Clean the air dome connection on the tub and the hose thoroughly.
- Check for leaks: Ensure that the hose has no cracks or pinholes that would cause incorrect pressure readings. Replace it if damaged.
- Test pressure switch: Use a multimeter to verify that the switch changes contacts at different pressure levels. Replace it if readings are inconsistent or out of specification.
- Control reset: After repairs, disconnect power for several minutes to reset the control. Run a test cycle to verify proper water levels.
