its more likely the brass valve at fault not the actuator.
the paddle in the bottom is likely to be cruded up or faulty allowing water to pass when hw only on.

useally just the valve.
remove the actuator and turn the spindle you may find it is seizing up/very stiff.
when the hw only is called for the valve closes the heating port by spring only.

If the spindle on the brass valve body turns freely, the problem is more likely to be either the actuator, or one of the other controls, ie thermostats or programmer.
