Only get hot water when timer is on

[normskii]

I've recently moved into a place with an Ariston Eurocombi.

At first I couldn't get the thing started at all, then I noticed that it was switching itself on but only when the timer told it to.

Better than nothing I suppose, but the problem is we can't get any hot water when the timer isn't on - and I don't really want the heating on all day!

Anyone got any clue what might be up with it?

timer is wired into the incoming live

That's very good. But is there a way to fix this easily, or will I need an engineer?

Btw

This was apparently because there was no (or a broken) diaphragm in the boiler. One is installed now, and we can get hot water without central heating.

Cheers though.
