How to Fix / Troubleshooting
Safety first: Unplug the unit and turn off water supply.
- Inspect pressure hose and air dome: Remove the top panel. Locate the small hose from the tub/air dome to the pressure switch. Remove and blow through it to clear blockages. Check the air dome on the tub for soap scum buildup and clean if accessible.
- Check switch mounting: Ensure the pressure switch is securely mounted and not rattling loose.
- Test switch: With a multimeter, test the switch contacts while gently applying pressure to the hose port (blow into it). If contacts do not change state as specified, replace the pressure switch.
