Hi I have a eurocombi 27 which keeps on over heating and when I turn it off the pressure drops to zero. Ive looked for leaks cant find any. the hot water runs cold after a few minits.Many Thanks
the boiler was over heating because of a loose connection on the Heating Tempreture Probe (NTC). This can be identified when the temp rise LED's are not on. Got it sorted just in time for Christmas :-)
