Possible Causes
Stuck relay on main PCB, Shorted power button contacts, Firmware glitch, Miswired control harness
How to Fix / Troubleshooting
Safety: Unplug the unit immediately if it does not respond to the power button.
- Power reset: Leave unplugged for 10 minutes, then plug back in and test the power button.
- Inspect control panel: Remove the UI panel and check for stuck or damaged power button mechanisms.
- Check main PCB: Look for relays that appear burnt or stuck. If the compressor or pump runs with the control harness disconnected, the relay is likely welded closed.
- Replace PCB or UI: Replace the main control board if a relay is stuck, or the UI panel if the button is shorted.
