I have a Powermax 140 boiler. The boiler has started to only intermittently work. Running the hot tap or demanding heating causes nothing to happen, but sometimes it spontaneously works fine. When hot water or heating is called for it doesn't lock out, nothing happens at all.
Is this the programmer again?

The hot water doesn't work when it's set to constant either so it's not the programmer. Anyone got any other ideas?
