sounds like it is the flow switch but you may need new sensors too, if you can still get them, if im correct they are old boilers and parts are becoming hard to find, good luck.

this is a common problem with the swiftflow flow switch, they scale up which causes them to either stick on or not operate due to reduced flow, you could try checking the balafix valve on the hot water outlet pipe first because these are very prone to blocking.
