Had the same problem on my boiler. There are a couple of things to try,
1 - check water pressure - should be around 1 & half bar.
2 - remove cover from boiler and check condensing tank which is located on the left hand side at the bottom and make sure clear with no sedement. If tank has sedement in it, it will need to be cleared out.
