Hi I have a Biasi M96 that was working fine but now only the hot water works ok. When the CH starts, it burns for about 1 min until the water reaches 30°C then cuts off the burner. The pump still runs and the temp drops to about 25° but it never re starts the burner.
If I run the hot tap the burner starts again, and then it switches over to the CH (with the burner still on) but only for a few seconds, then switches off the burner as above and never restarts.
There are no warning lights and it all seems OK other than it never switches on the burner again.
What is wrong??
THanks
