Frequently Asked Questions

What is an E3 error on an Astral heat pump?
An E3 error code on an Astral heat pump indicates a flow switch fault — the unit is not detecting sufficient water flow. This can be caused by a failed flow switch, low water flow through the system, or a blocked filter. If flow and filtration are confirmed to be adequate, replacing the flow switch is the recommended next step.

Will replacing the flow switch fix my E3 error?
In most cases, yes — if water flow through the system is confirmed to be adequate and the filter is clean, a faulty flow switch is the most likely cause of an E3 error. We recommend having a qualified pool technician or electrician confirm the diagnosis before replacing the part.

Which heat pump models does this flow switch suit?
This flow switch suits the Astral Pinnacle IHP SD 250 and SD 315, and the Astral Viron IHP195, IHP242, and IHP283 inverter heat pumps. Call us on 02 9137 8914 if you need help confirming compatibility with your model.
