We have a Biasi Riva Compact M90E model 28s

Recently we are not getting any hot water, only cold from all taps and bath tub. The boiler seem not to be igniting although there is noise from the boiler when hot water taps are run.

Please could someone help us resolve this problem

Does the CH work?


Open the front and peer inside. WHen the tap's on you should see a red LED, Do you?

Crummy pic - the led's on a black plastic block you can rotate easily fowards/back to reveal the led.

When the tap's on we see a red LED, but there is still no hot water, and neither does the boiler ignite

The c.h. is not working; the boiler starts up then after a short time the middle light (LD2) turns RED.

whats the system pressure
that's where the water in the system exerts a pressure equal to a head of water(or height) 10m of water exerts approx 1bar of pressure. it is indicated on a gauge that is often integral to the boiler - thought you'd have known that Kev ;)
