What to do if Beretta EXCLUSIVE GREEN HE 25 B.S.I. shows FLAME FAILURE BLOCK (D)?
- AAaron WilliamsAug 5, 2025
If your Beretta Boiler displays 'FLAME FAILURE BLOCK (D),' check the system pressure. If it's insufficient (below 0.4 bar, in the red area), refill the system as described in the 'Filling and emptying the systems' chapter. If the pressure is sufficient (above 0.6 bar, in the blue area), the issue is likely a lack of water circulation, and you should contact Technical Assistance.
