drained central heating to add new rad, didn't turn off electric to programmer and now it doesn't work. Had air in system but have bled all radiators produce water at bleed point but heating will not kick in. No lights on programmer and not allowing you to select programme. Is it the battery, it hasn't been changed in 6 years or is there a reset button somewhere or some other problem.
Its a potterton EP2001 programmer.

After 5 days of trying to fix the programmer, eureka. Maybe the threat of buying a new programmer has kicked it into action or maybe the battery has recharged itself. anyway it now works without a new battery or new programmer so perhaps patients is all it needed. thanks for your help.

I have a background light but not function selection on HW or CH.

Have tried turning on and off, have taken front cover off but still nothing.

try taking the programmer off the wall, then replace it. believe it or not this sometimes works, is there power on the live when you take the programmer off?
