hi There,
I have had similar problems to you for the past 7 months.
I have had 4 "Engineers" out ALL stating different causes.
New Pump....still shuts off..
New Divertor Valve......same...
New Thermister...same.............NIGHTMARE..
Boiler shutting down after 15 secs..then fires up then shuts off...cools down...fires up....shuts off....CONTSANT LOOP....
Then i noticed that on the hot feed to rads"T fiiting"..1 leg was warm other 2 legs was HOT.
I dismantled "T fiiting" and could see the problem..IT WAS SOLID!!! I had to clear the fitting with a screwdriver...
It seems that the water was not being pumped around system.
"Why didnt any of the 4 so called "CENTRAL HEATING ENGINEERS/MUPPETS...pick this up.
Also flushed the system myself at the same time(After being quoted £1200 from Blitish Gas!!!
Now 100% "Toasty Warm"...TOO HOT NOW...IMOA..lol...
PS (Im in the wrong job...)..If anyone wants there system "Power Flushed"...CALL ME !!!!Ha Ha...
