Braemar Fault Code 03

Fault: PS low opened during run

Potential Cause (Technical Use Only: Potential remedy):

  • Swarf obstructing combustion fan pressure tapping. Check both ends of pressure tapping – clear obstruction or replace pressure tapping.
  • Condensate intermittently blocking combustion fan suction hose. Clear blockage. Check flue condensate drain fitted correctly (condensing models only).
  •  Flue partly blocked, making system more susceptible to wind effects. Check and clear blockage, check flue cowl is not pushed on too far.
  • Severe wind on flue terminal, or poor flue terminal location (eg, too close to roof). Check flue terminal location – re‐ locate if necessary.
