Potterton Prima F40 doesn't work and display of the timer is empty???
I've just moved in to the house for 2 months. When I moved in, the heating worked properly. But now there is nothing on the display of the timer, the model is Landis & GYR rwb200. And also the light of the boiler is not on. Is the problem about the timer or the boiler? Please advise. I have no idea at all because I've just come from another country and never use the boiler.
Sounds like the programmer is faulty but have you checked the fuse in the fused spur, it should be a 3 amp one. Sometimes just switching the power to the progrmmer OFF then turning it back ON again works.
