Customer Question

I have an ariston combination boiler.
When I put the central heating on it ignites but after a while it turns itself off again and then re-ignites. This gets quicker and quicker (every 2 seconds) as it heats up
The pressure gauge is on 1. Normally it's on 2 and a half
Any ideas as to what this problem maybe?

It sounds like the flame detection probe is cracked or dirty, causing problems when the unit is hot.
Are you able to top the system back up to 1.5 bar and let me know the last time it was serviced?
