 Hot water pump CH - Zero
The diverter valve(s) are commanded to work by the thermostats/programer, they move, make a microswitch to command the boiler, the boiler commands the pump (because it needs to run the pump after the heating cycle to prevent heat soak in the heat exchanger)

If you have have an open vented system boiler, which it sounds like. Sounds like you valve(s) are borked, they fail the most in any system
