Worcester Bosch 35cdi Leak

[Rudie]

Hi all

Started to get a leak from underneath this boiler last few days. The pressure isn’t dropping on the system so assume it’s the inlet that’s leaking. Water is clear-ish as well.
I’ve opened it up and taken some pics of the leak below to see where the leak is coming from. Any advice appreciated thanks.

Looks like a leak on a hydroblock, and will need a 26.9 safety check (performed by a competent person, usually a gas safe registered engineer) after removing the cover on that boiler.

Thanks Chris. A few months before this issue, I noticed that the boiler would like vibrate for a bit when running hot water. Then after a few seconds it would stop when the tap was opened a lot more. Not sure if the two are linked. Will contact an engineer.

Got the part changed but the vibrating random noise is still there when using hot water / and nkw when heating is on. Does anyone know what’s causing this? The water pressure is good in my area and the boiler pressure is at 1bar...

The vibration might just be the boiler casing resonating (i.e. vibrating at its natural frequency, set off my the frequency generated when the hot water is on). Try putting something non-flammable between the casing and some solid part and see if that stops the vibration. If it does then just sticking something (non-flammable for safety reasons) to the inside of the case to change its natural frequency of vibration might be all you need for a permanent solution.

Hi, thanks for the advice. Its alot more than rattling its more a vibration. I will remove the case this weekend as you say and see how it goes.

Hi, casing was removed and left for 2 days but the vibration was still there unfortuneately...
