Common IBC Combi Boiler Problems & Fixes
The most common IBC combi boiler faults — no heat, no hot water, leaks and error codes — and how we fix them.
Like any combi boiler, IBC units can develop faults over the years. Here are the most common IBC issues and how our licensed technicians resolve them across Greater Vancouver.
Common IBC faults
Typical issues on combi boilers including IBC are no heat or hot water, low or dropping pressure, leaks from the relief valve or pump, ignition lockouts, and error-code faults — most of which are repairable.
