Baxi 105e cannot identify issue

[JayE]

Hi all, was wondering if someone would be able to help identify the issue. It seemed like a simple diaphragm replace (hot water running intermittently - sometimes not at all).

However I opened the casing and found a part which appears to have quite a nasty leak.

Is anyone able to identify this?
