we have a glow worm swift flow80 boiler fitted in our house sudenly it stoped giving hot water if we turn central heating on it gives hot water otherwise there is no hot water.
It's your water flow switch... These are shuttle-type switches and sometimes get stuck, you can try and get it cleaned, but to be honest, it's best to just change it.
You need a CORGI Registered engineer to do this job as the top nut for the flow switch requires access to the combustion chamber.
