Well I am about to replace the second pressure guage. ( The half circle version) Both faulty gauges show little pressure. I have taken the guage off the machine and looked for scale that might be blocking the pipe. The pipe is quite clear as far as I could reach with a pin. The hole into the boiler was clear of any obstruction. I am not sure if others have repaired the guage or got one working. This guage has lasted about 18 months.
If any one has any information it would be helpful before I fit the new guage.
It was at zero pressure before I took it off. I sucked a bit of water out of the pipe and today I got about 3bars pressure. Do they fill up with water?
