Q: Hi. Have had an Ivory11 10.5kw for some years, worked fine until about last Christmas. Had a lot of trouble with not heating up, felt it was a lack of mains pressure, called Anglian Water who admitted many leaks due to the adverse weather. Then the solenoid valve failed in the open position, so I fitted a new one. Since then, and during the better weather it's been quite good, but recently playing up again. Sometimes, pressure seems quite good, but I can feel the water temperature fluctuating slightly all the time I'm showering, similar to when the head is clogged, but it's not.On occasions it won't run hot at all, but you can leave it for a while and try again and it works fine. But yesterday it excelled itself, working fine for a few minutes, suddenly got very hot, accompanied by a noticeable drop in pressure at the shower head, then the cutout operated and it went cold. We've had this happen when somebody turns on a tap or flushes the toilet while someone else is showering, but this time nobody else was in the house and all appliances switched off. One thing I've noticed is that when the sfaety cutout operates, it seems to take a long time before it resets. Ideas please?
