Question:

Furrion tankless water heater, model FWH09A, 11 months old. Code E05, no exhaust fan noise. I blew out the exhaust pressure sensor hose, no resistance or water, checked the fuse, good. Reseated the blower connector, powered unit off for two minutes, still not working

Hey Jim, an E5 error code on a Furrion RV Tankless Water Heater # FR93FR means that you have an Air Pressure issue. This means you could have the following issues:

Exhaust Blockage: Remove any obstructions to the exhaust vent/clean off.

High Winds Blowing On Exhaust: Move or reorient the trailer or motorhome away from high winds.

System Fault: You'll need to contact Furrion as there's an internal error that only they will be able to fix. Their email is [email protected]
