I have a Vokera Combi Boiler in the house I have just bought, but I noticed the pressure kept dropping to below 1, so I kept topping it up to around 1.5
After a few weeks of doing this daily, I had a plumber come out who replaced the vessel, with no luck it kept doing the same, by this point the pressure was going all over the place, it would sometimes be at 3 and then an hour later be at 1.1
So I called him back out, and he cleaned the system out with a fluid he put through the system, no luck after that - so the third visit he put a sealant through the system as he suggested it might be a small leak causing the pressure to drop.
A few days have past since he put the sealant through it and now the pressure is dropping alot fast than it was before, 3 times a day going to check it and there is a red light flashing with the number "04" appearing.
Can anyone suggest what is causing this constant pressure drop? The boiler is around 10 years old if that helps with suggestions.
What are the next steps?
