Furrion FWHO42SB1 (tankless) error code E2
Detected fake flame signal - a flame signal is present when it should not be. System Fault - contact Furrion. CONFLICT with the FWH09 family: on FWH09/F2GWH, E2 is flame LOST during operation and the false-flame code is E9; on this 6 L unit E2 IS the false-flame code. Confirm the model before using any E2 meaning.
