My vaillant boiler won't re-pressurise even after turning the two valves

Thanks for the update, and good result.
System sludge? Blimey.0 -
The power clean is NOT supposed to pump the sludge into the boiler. The heat exchanger can get blocked. It may be worth flushing the boiler?tasticz said:Hi all just an update.The boiler is fully up and running.As plump1_2 said it was the Vaillant fill valve which was blocked (full of sludge). We did do a power flush couple months ago and the engineer said that it might be they engineer who did the power flush didn’t isolate the boiler while doing it which may have caused all this sludge from pipe work to go inside the boiler…
Anyways happy days for nowNo reliance should be placed on the above! Absolutely none, do you hear?0 -
Do you have a mag filter fitted, Tasticz? That, and a dose of X400 should show whether you have sludge remaining, and steadily remove it.0
