What it means
The manual says: Error due to pipe rupture protection.
Part involved: Water circuit pipe rupture protection.
When it shows: Unit self-diagnosis: Error due to pipe rupture protection.
Likely causes:
- Pipe rupture protection triggered (possible water leak/pressure loss).
- Engineer checks per Samsung service manual: Check water circuit for pipe rupture/leak and system pressure.
Is it safe?
Switch the heat pump off at its isolator and call an engineer.
| Does the heat pump stop? | Yes |
|---|---|
| Engineer needed? | Yes |
The heat pump stops until the fault clears or is reset.
Resetting itself: unknown.
Manual reset: unknown.
What you can check
- Note the full error code shown on the controller; check the heat pump breaker/isolator in the consumer unit is ON; check the heating system pressure gauge reading (typically 1-2 bar when cold; do not top up unless you have been shown how); look for visible water leaks from pipes or the indoor unit without opening any casing; then contact your installer or Samsung service; Samsung manuals do not describe a homeowner reset for this code.
What the engineer will check
- Check water circuit for pipe rupture/leak and system pressure. Any work inside casings, on PCBs, wiring, sensors, pumps, valves or refrigerant is engineer-only.
Who to ask for: Heat pump installer (wet system).
Certification: None specific (plumbing competence).
