E119/E118 - boiler has detected low pressure

Top up your boiler pressure

Your boiler has detected that the pressure is too low, so you need to top it up.

It is quite normal for the boiler pressure to need topping up from time to time, and this is something you can easily do yourself, especially as your boiler has an Easy-Fill permanent filling link.


Please watch this video to find out how to top up the pressure

Why does the pressure drop?

A few things can cause the pressure in your boiler to drop. If you have bled your radiators recently, pressure could be lost. Or it may be that there is a leak somewhere in your heating system. The leak could be so tiny you haven’t noticed, but if you have to keep topping up the pressure, you may want to ask your installer or Baxi Customer Support engineer to check the rest of the system next time they service the boiler.


What should I do if I can’t top up the pressure myself?

If you are worried about topping up the pressure, please call your installer or Baxi Customer Support [link]. However, you may be charged for a visit.
