Hi from a new member and thanks for taking the trouble to read this.
Problem is that the water has not been heating. Inspecting the MA1 actuator shows the black lever firmly in the H sector and I assume it should go to either the M or W when the cylinder thermostat is demanding. I flipped off the actuator and the little black indicator lever fell off inside. Turning the cylinder stat on or off causes the actuator to make a brief noise but no movement happens. The silver spindle will only turn a small amount with the fingers, say 20 or 30 degrees; should it turn a lot more? Is it only the actuator that is duff?
