What about the valve itself? pcb sending the signal to move to the actuator?

First check flow turbine. Go to 6.d on the service menu, turn on a hot tap if the reading stays at zero change the turbine.

what about the hw flow switch? is it recognising the hot water demand? the paddle can break inside the flow switch on these and obviously if you renew it make sure you put it in the right way up.
