THERMOSTATIC CONTROL FAULT ON A WORCESTER BOILER

[BABLINGBROOK]

Hi
After four years of unbroken servise the boiler has suddenly decided to not respond to the wireless controler.
Have replaced the battery's and had plumper out to have a look at problem.
He says that we have the control on the boiler set to the incorrect setting.So I said that is the setting it has been on for the last 4 years with no problems.
So he left it on the setting that says ON???
I said that means it will be on all the time.
Anyway it was working ok but today agian it stopped.I pressed the OK button and put back to timed and away it went.
But hour an hour later it stopped again??
Help some please.

I have seen some plumpers on a differnet web site

You haven't said which of the miraid of Worcerster boilers it is, they tend to bring a new model out every week, which does exactly the same as the rest, just has a different name.
