Common Viessman Boiler problems

Sometimes boilers have issues, we all have our off days. So, we’re here to know a list of common problems that you can fix at home or can be sorted by one of our gas safe engineers quickly.

  • Blocked condensate pipe – this is a common problem, usually occurring in cold weather, resulting in a boiler lockout. A simple thaw and reset will clear the F4 EE fault code.
  • Burner blockage - The burner is needed to supply the fuel and air to generate heat. When this is blocked your boiler won’t be able to operate fault code F1 or A4.
  • No hot water – this may be caused by a faulty diverter valve (characterised by functioning heating), a power shortage, a stuck Y/S plan valve, or other faulty components.
  • Leaking boiler – this is usually caused by a blown pump seal, which degrades over time or may have come under too much stress with the flow rate. 
  • Boiler losing pressure – this is caused by a leak in the boiler or central heating, such as a pinhole in the radiator. This causes the boiler to lockout when the pressure drops too low.
  • No power – this may be caused by a faulty PCB or a tripped spur socket/RCD unit.
  • Banging noises – these may be caused by an airlock in the central heating pump or a kettling heat exchanger.
  • Overheating – this may be caused by a burner in fault mode /emergency operation. Look for Fault Code F6, 58, F9, F-E1, F-E2 and F-F6.

If you have a frozen condensate fault then you can learn how to thaw a frozen condensate pipe right here. You may be able to fix pressure issues and small leaks without calling out an engineer, but always ask if you are unsure.

All other issues are related to components and must be dealt with by a Gas Safe Registered engineer.
