same as baxi 2 posts below, get a manual from partsarena.com/baxi and locate hot water flowswitch area then remove front panel and observe what happens.

working- open hot tap, pin will pop out of brass housing and press microswitch firing boiler and giving hot water.

broken switch - pin will come out and hit switch but boiler will not recognise it

diaphragm split - pin will stay hidden away and do sod all. with hot tap open press switch with something long and plastic, boiler fires? replace diaphragm.
