Promax Combi HE Plus- error 119
Hi,
My Promax Combi HE Plus shows error 119. Does anyone know what the issue is and how to fix it?

Hi Mark,
It is a common error, it appears each time your boiler’s primary water pressure is lower than 0.5 bar. To fix it you need to re-pressurize the system, optimal pressure starts at around 1-1.5 bar. Don’t forget to reset the boiler after you finished.
