Hello, newbie here, been trying to figure out whats up with our boiler and lots of google searches come back to this site so thought I'd jump in and see what advice you lovely people can give.

We have the ideal Isar HE30 yes I know it sh*t I'm another warmsure victim who was told "its wonderful, you get a free boiler installed yay!" and its been nothing but trouble ever since!

Anyhoo hot water and heating went off, boiler flashed its L9 error and and the pressure was low, so I repressurised and all was good for 24 hours or so, then it all went of again, no water no heat L9 message but pressure was ok.  Tried to simply press the reset button (you never know, sometimes it works )  and next minute a small buckets worth of water comes out of the bottom of the unit! Yikes! water stopped after the initial gush and was followed by dripping for about 10 minutes and is now dry again.  

Reading other threads on this boiler and its many faults I'm wondering whether the water was due to a blockage in the condensate trap?


I know this fault is sometimes the pump too and from what I've read I can check both of these myself.

COuld you guys please give me a step by step idiots guide to how to check these things and any other advice as to what it could be?
Thanks in advance x

PS I also suspect that our 20 yr old lad tried to repressurise whilst I was out because he saw me do it the day before and saw that it fixed the issue (temporarily anyway!) if he did and the pressure went too high could that have caused the water gush!?

May have been driving rain from the last week or so getting in the flue, in all fairness you should get it checked
