Common problems

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

  • Radiators failing to reach temperature – this could be the result of too much air in the heating system.
  • Low boiler pressure – characterised by an E119 error code, this could be an indicator of a leak in the system. Low pressure can also be seen on the pressure gauge, with the needle pointing to a value of less than 1. A value of 1.5 is ideal.
  • No hot water – if your taps are running cold, this could be a fault in the diverter valve.
  • Frozen condensate pipe – if your boiler displays an E133 error code, this could indicate a frozen condensate pipe. These pipes run outside and risk freezing in winter, causing lockouts.
  • Boiler keeps turning off – this may be caused by many issues, including low water pressure, thermostat problems, or a lack of water flow

If your home doesn’t feel warm enough, you may be able to remove the excess air by bleeding your radiators. Likewise, you can thaw a frozen condensate pipe without having to call an engineer, and may be able to adjust boiler pressure manually.

Component issues, such as a faulty diverter valve or thermostat issue, must be dealt with by a Gas Safe Registered specialist.
