How to Fix / Troubleshooting
Safety: Turn off power before working near leaks. Water can damage electrical components.
- Identify source: Remove the front cover and use a torch to locate the exact point of leakage (pump, valves, joints, or heat exchanger).
- Protect electrics: Place a tray or towels to prevent water from dripping onto the control board or wiring.
- Tighten joints: For minor weeps at compression fittings, gently tighten the nut by a small amount. Do not overtighten.
- Replace faulty components: Leaking pumps, air vents, or heat exchangers must be replaced by a qualified technician.
- Repressurize: After repair, top up system pressure and bleed air.
