VAILLIANT TURBOMAX PLUS 828E LOSS OF WATER PRESSURE?
MY VAILLIANT BOILER APPEARS TO RUN OK WHEN I FILL TO 1/1.5 BAR BUT THE PRESSURE GAUGE KEEPS DROPPING VERY SLOWLY TO ZERO CHANGED THE PRESSURE RELIEF VALVE BUT STILL NO CHANGE RADIATORS ARE FULL
When did your guarantee run out for this boiler? Was the fault found on the exact same day, but 2 or 3 years later? My boiler has just done that. It is not detecting a decease or increase in pressure. Trying to fix it now.

Theres gotta be a leak somewhere, that water has to go somewhere! Check all parts of system, rad valves, radiators, visable pipework.
