Winter weather advice - What to do if you are having problems with your boiler

Cold weather like we’re having at the moment can lead to boiler faults caused by a frozen external pipe, triggering the following error codes:
  • E133 - Potterton/Baxi boilers
  • EA227/9 - Worcester boiler
If you see one of these errors on your boiler and you're able to, please try the following steps to resolve the issue before reporting a repair.
  1.  Find where the pipe is frozen; this is usually the most exposed part of the pipe. Take care if the floor is frozen to avoid slips or falls.
  2. Warm the condensate pipe (usually a white plastic pipe) across its exposed length using either a hot water bottle, a microwaveable heat pack or warm water poured from a watering can. Please do not use boiling water straight from the kettle, as this could damage the pipe.
  3. Restart/reset your boiler.
  4. Repeat the process until the boiler works again.
