Modena 80E Hot water Problem

[simon_225]

I have a Ferroli Modena 80E boiler.

The problem is the hot water will not come on automatically you have to turn on the central heating then the hot water is avaliable.

Normally when you turn on the bolier the central heating comes on.

Thank you for your help in avdance

Flow meter or DHW sensor. If the tap symbol is lit when you are drawing DHW the fault is likely to be the sensor. If the light doesn't come on suspect that the meter has not operated.

Therefore, the DHW light does not come on when you turn on the tap. You are saying the mainboard is gone.
