hi people,
hot water ok but central heating failed.
the three port is a acl 679H340-30L0,it has the manual lever on top,if i move that across and lock in position (fill position) CH works fine,once i kill the power completely the lever will move back across to HW only,then with power back on CH will fail untill i move lever back across,would this suggest that valve is ok and that the synchro motor has failed?
i can get a motor for £15 and replace my self of i can get a plumber to replace whole unit with a new one for £200.
thanks in advance
