AstralPool HiNRG Gas Heater Error Codes – Causes & Fixes
AstralPool HiNRG gas heater error codes are the same as Viron gas heater error codes, as both heaters use the same control system and fault logic.
If your HiNRG heater is showing an error code such as F0, F1, F2, F6 or F7, the meaning and fixes are identical to the Viron gas heater range.
This guide explains what HiNRG error codes mean and links you to the correct fix for each fault.
