Baxi Combi Boiler

Hello All,

I have installed my Baxi Duo combi boiler four years ago. Everything was working fine but from last two days boiler is showing an E119 error code. What should I do to resolve this issue?

Thanks a lot in advance

Hi Mark,

Hi, according to the Baxi Duo combi boiler’s user manual E119 indicates low water pressure. You can solve this problem easily at home by simply re-pressurizing your boiler. Firstly, switch down the thermostat to low because by doing so thermostat will not call for heating. Now, re-pressurize your boiler to 1.5 bar & afterwards turn off its flow & return controllers under the boiler. The standard operating pressure of water is between 1 & 0.2 bar. In case, the water pressure goes beyond 3 bar, all the safety pressure controller will operate & error code/fault is shown.
