Hi i went on holiday i turned my heating down to 13 when i came back i pressured the boiler and turned the heating on i have a hive which says its actual 13 when i turned the heating on the boiler says preheating off when i put pressure on to 2 it goes down quickly
The boiler is an ideal combi c30

So, in short...

The pressure gauge is showing the system is not holding the pressure you are putting it up to?

You set it to 1.5 bar and it immediately drops to...? 0?

So you have a leak. That is why the pressure is dropping.

Does the pressure go up before going down?
