Breville Barista Express - Solenoid Block Testing

Testing out the old and new solenoid blocks to see if we can find out if this is the source of the problem.

It seems the 2/3 way Olab solenoid is indeed the source of the buzzing sound. Electrically, all the solenoids test out, but that one buzzes when actuated. The new Ceme solenoids see to be higher current/power and have a much more solid sound to them when changing state than the Olab solenoids. It seems Olab solenoids are used in many Breville coffee machines judging by the eBay listings. It looks as if Breville has changed to the Ceme brand lately.
