Yes I think so.
Expert:  Plumberpro replied 1 year ago.
Hi it may be that the motorised valve is stuck in the open position. With everything off , ie ch and hw off feel the lever on the motorised valve. It shouldn't be loose but it should feel a bit of resistance when you manually push the lever across
Customer: replied 1 year ago.
It is permenantly loose when pushed. If the system is on or off
Expert:  Plumberpro replied 1 year ago.
Ok , I think the mechanism must be broken I think the whole valve may have to be replaced and not just the head, just in case the valve body is stuck .
