Junkers Service interval reached

Boiler displays H7; service reminder or maintenance required

Possible Causes

Elapsed operating hours or burner cycles exceeded, Time-based service reminder active

Safety: A service reminder is not an immediate fault but indicates maintenance is due.

Schedule service: Arrange for a qualified Junkers technician to perform annual maintenance: cleaning burner and heat exchanger, checking gas pressures, testing safety devices, and inspecting flue.
Reset indicator: After service, the technician will reset the H7 reminder via the control panel or service menu.
