If the pressure drops below the manufacturer's recommended level, the boiler's safety mechanisms shut it off to prevent damage. You can usually check the pressure using the pressure gauge on the front of the unit. If it's less than 1 bar, it's probably too low. Repressurizing the system may be a temporary fix, but recurring pressure drops could indicate a leak s...
