Hi Guys,

I have a Vaillant 828 2E boiler with a timer switch 110 fitted - about a month ago the timer switch stopped working so I order a replacement, the new replacement switch came and I replaced it, after three days of running it also stopped working, so ordered another one, then again after two days that one stopped working. they seem to stop at night no tick-tocking they've all just stopped.

Today I just turned off everything and turn on everything but the timer switch didn't start running again, so I turned everything off and took the timer switch out again then simply put it back in, turned the power on again, and now it works, for how long no one knows.

What else can it be and can anyone help????
