I have a worcester Heatslave 20/25 boiler. I am having trouble with the heating coming on at random times and not how I have set it. The red light is not on but the heating is blasting away. I have had to switch it to off then put it back to timer. At times I have to switch the hot water off to stop the heating! Can anyone help - my plumber doesn't seem to know what the problem is.
