Vokera Excell 80SP

[tanker]

Hi there everyone.

I have a Vokera Ecell 80SP that seems to be having problems delivering hot water.

When the central heating is off, if you trun on a hot water tap no hot water is produced, the water just runs cold.

When the central heating is running hot water is produced (Although I seem to think it's not quite as hot as it was).

Initally my wife complained that during filling a bath after a while the hot water ran cold. I never experienced this but could it be related?

Any ideas as to what may be causing this?

Most often it's the diaphragm in the water section.

Agree with chris change diaphragm first a cheap part & easy to change it after you have removed fulcrum arm
