If the hot water is reaching the pump check the pump outlet, if the is coming from the pump outlet then qll the isolation valve are open towards the shower then you should have hot water, if not change the shower thermostat thats should slove the problem.

Filter on the hot side could be blocked so no water coming through

Turn your shower on with out shower head on .if u have a exposed vavle you can feel if left hand nut is getting hot before valve . If hot then its your valve . If cold then its your pump. I would say your valve is probably scaled up and resticting the flow
