Furrion tankless water heater filter cleaning or descaling maintenance

Use this when Furrion tankless guidance points to owner maintenance for the water filter, hard-water scale, or descaling before service.

Owner-safe checklist

Turn the water heater off before owner-accessible filter or descaling maintenance.
Use only the Furrion/Lippert maintenance procedure and chemicals allowed for the model.
Do not open gas, electrical, blower, valve, or controller areas.
Call Lippert/Furrion or a qualified technician if flow or temperature does not recover after allowed maintenance.
