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.
