Pressure on valliant eco boiler

Anonymous user 14 March 2024 - 2.33 PM

My hot water runs hot for about a minute and then runs cold. The pressure gauge is way past the red and is in fact is nearly back at the start F74 which according to the instructions say it is : Water pressure sensor signal outside correct range (too high).

Are you a tradesperson and able to answer this question?

In my opinion and experience, the problem that is solved by replacing the boiler expansion vessel. Avoid replacement to save some money for a period of six months.
