Furrion tankless water heater low flow or low temperature
Use this when a Furrion tankless water heater has low hot-water flow, weak heat, cold-water mixing, hard-water scale, or slow temperature rise.
Use this atlas to identify likely meaning and prepare for service. Shut off power, LP gas, fuel, or water when a listed appliance condition involves flame, gas smell, exhaust, generator shutdown, high temperature, moving jacks/slides, refrigerant, 120 VAC, control boards, repeated ignition failure, or a persistent lockout. Call the appliance maker, RV dealer, or a qualified RV technician for repair.
Owner-safe checklist
- Confirm LP, water, and 12V power are on from normal RV controls.
- Check that shower and bypass valves are closed so cold water is not bleeding into the hot side.
- Clean owner-accessible faucet screens or inlet filters only if the manual allows it and you can do it without disturbing gas or electrical parts.
- Call Furrion or a qualified technician for persistent low temperature, gas-volume, altitude, or internal service concerns.
