My Glow Worm 30cxi pulses on and off very fast like once every second
the green led blinks, and at the flue you can fell the on/off blows and there
is little smell of gas,
It happens especially when using hot water, but sometimes also when just
heating the radiators.
There is no faults showing (F..) and the hot-water gets warm but not too hot,
and it is annoying and the unit sounds a little like an old ambulance.
In the manual on page 37 The Faultfinding diagram the sympton is described
"Does Boiler modulate before desired set point is reached"
yes -> temperature rise too high of flow rate too low
But I cannot find a description of what I should do fix it.
What is happening and what can I do to fix it.
