Panasonic Aquarea H62: read it as a water-flow fault

What Does Error H62 Mean?

Panasonic's Aquarea end-user guidance identifies H62 as a water-flow error and directs the owner to an authorised installer. The code says required circulation was not confirmed; it does not decide whether the cause is system pressure, a closed valve, trapped air, blockage, pump operation, sensing, or wiring. Applies to: Aquarea air-to-water heat pumps This answer applies to Panasonic Aquarea air-to-water heat pumps within the cited European end-user manual. Panasonic residential air conditioners use H codes too, but their meanings must not be transferred to Aquarea. Owner-safe checks: Photograph H62 and the visible pressure value, note the active heating or hot-water demand, and check only for external water leakage. Qualified technician: Pump, flow-sensor, valve, strainer, pressure, venting, wiring, and internal hydraulic checks belong to the authorised Aquarea installer.
