Heat Pump High Pressure Fault in Crowthorne AH
The unit locks out on a high pressure error, often after running for a while. This page covers how we diagnose and repair it on heat pumps in Crowthorne AH.
This fault is normally treated as priority work because the plant is still running but is damaging itself or wasting energy while it does.
Crowthorne AH is an extension of Midrand with a mix of original and renovated housing, so geyser positions, pressure control and pipework standards vary stand to stand. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

FAQs
Frequently asked questions
What causes heat pump high pressure fault?
The usual causes are poor water flow through the condenser, scaled heat exchanger, overcharge of refrigerant, non-condensables in the circuit. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Measure water flow rate and delta-T; Check condenser approach temperature; Verify charge by weight; Inspect strainers and valve positions. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
Usually yes, for a short period, but efficiency and component life are both being lost while the fault persists.
Do you attend this fault in Crowthorne AH?
Yes. Midrand and Centurion sit between the Johannesburg and Pretoria routes, so attendance windows are usually the shortest of any area. Attendance in Crowthorne AH is grouped with other Midrand call-outs, which usually means a same-day or next-morning slot.
