Mend Alpha CB28 Water Dhw Boiler

Water dripping from hole under DHW flow switch on Alpha boiler?

I have a Alpha CB28 Combi Boiler that has a constant drip of water from a hole that is located in the pipe directly under where the DHW flow switch is positioned. The amount of water was very little at first but recently the flow has increased. Does anyone know the solution?
Thanks for any advice.
