Heat Pump Pressure Fault in Delmore
Heat Pump Pressure Fault is one of the faults we attend most often in Delmore. It is a symptom rather than a diagnosis — several very different failures produce the same behaviour, which is why measurement matters more than guesswork.
Below are the causes we actually find on site, the process we use to separate them, and how quickly we can get to you. If stock, trading or comfort is at risk, phone 069 268 0988 rather than waiting for a form reply.
[probable_causes]
What we typically find
- Airflow restriction across the evaporator
- Water flow restriction across the condenser
- Overcharge or non-condensables in the system
- Failed pressure switch or sensor
[diagnostic_protocol]
How we isolate the fault
- Verify inlet and outlet water temperature rise across the condenser
- Confirm water flow rate — most 'not heating' calls are actually flow or circulation faults
- Check high and low pressure switch operation and refrigerant charge
- Test the defrost cycle, four-way valve and evaporator fan operation
- Inspect the controller, temperature probes and element back-up wiring
- Check the geyser, thermostat, non-return valves and pipe insulation
