I have a PROTHERN 100EC Wall hung combination boiler When we turn on the hot water taps only cold water comes out but the red neon light comes on indicating that the hot water is on
Thanks carefree for your help, got an Engineer coming out Monday will let you know what the problem is.

Totally unfamiliar with this boiler.
From the fault finding instructions, hope it helps:
DHW flow is poor
If DHW floor is poor or boiler does not start when hot water tap is open, check following:
Cold water supply pressure is at least 1 bar.
Check if the cold water filter or flow regulator (plastic “O” ring) is not clogged.
Check free movement of the magnetic shunt (mounted inside cold water filter).
Note: The Hall Effect Sensor is polarity sensitive, consequently the magnet must be kept in the exact
position. Before completely dismantling the Flow Detector, print a mark on the visible face of the magnet, in
order to reassemble it with the right polarity.
