Possible Causes

Pressure switch stuck in full position, Blocked pressure hose, Siphoning through drain hose, Faulty pressure sensor

How to Fix / Troubleshooting

Safety first: Unplug the unit and shut off water supply.

  • Check drain hose height: Ensure the drain hose is installed at the correct height and not sealed airtight into the standpipe, which can cause siphoning.
  • Inspect pressure hose: Locate the small hose from the tub to the pressure switch. Check for kinks, blockages, or water trapped in the hose. Clear or replace as needed.
  • Test pressure switch: Remove the hose from the switch and gently blow into the switch while measuring continuity changes with a multimeter. Replace the switch if it does not respond correctly.
  • Reset control: After correcting issues, unplug for 1 minute, then restore power and test a cycle.
