We have had long term problems with the hot water not switching on. Plumber replaced flow switch with original Alpha part which worked briefly. Valve and diaphragm were then replaced, Again, it worked briefly, then back to normal. I then bought this part and fitted it. It's extremely easy. All working perfectly now!

This takes a few seconds to replace and needs no tools, once front panel is dropped (2 screws). Boiler was refusing to fire when hot tap turned on. Replaced and fired up immediately and hot water working fine. Easy DIY as no gas or water pipes touched and simple plastic electrical connector, Blue and brown wires only.
