Leaking heat pump hot water system: act safely
A drip under a pipe and water running towards an electrical cover demand different urgency. Stay on dry ground. Keep every panel closed, then note the first visible wet point only if it can be seen without approaching the leak.
Observed symptom ≠ diagnosed fault
What this can tell you
Treat the location of water as safety information
A wet concrete pad, a bead of water on a pipe and a growing puddle are useful observations, but water can travel before it becomes visible. Do not follow it into the cabinet, remove insulation, tighten a fitting or touch wet equipment to investigate.
Water at or near wiring, electrical covers, the isolator or switchboard belongs on the urgent red-flag route. Otherwise, observations made from a dry, safe position can help a licensed plumber understand the amount, location and timing.
Four checks, then a route
Choose a clear next step
Is water near electrical parts, wiring or another danger sign?
Keep away, stop using the unit and follow the urgent licensed or emergency instructions above.
Can a controller code be read from a dry and safe position?
Record the exact code without touching the unit and check it in the search below.
Can the brand and model be identified without crossing the wet area?
Use the brand directory for official support; do not approach merely to read a label.
Is the leak away from electrics but still active or recurring?
Arrange licensed repair help and describe the observed flow without attempting a plumbing fix.
Letters or numbers on the controller?
Copy the display before choosing support
Only use the search if the display is safely visible from a dry position. The result may explain a manufacturer-documented code, but it cannot identify where the water originated.
