ECM Synchronika: Hot Water Valve Seal Inspection/Replacement

If you close your hot water valve on your ECM Synchronika espresso machine and experience a leak (it is normal for steam to escape for a couple seconds), the valve seal may have an obstruction, or need replacing.

To perform this repair you will need to have your machine unplugged and completely cool.

Tools needed:

The first step is to remove the top and side panels.

Next, using the 2.5mm and 3mm allen keys, remove protruding frame component.

*When the nut is removed, be careful to not let it fall down the copper tube, it can slide down and it's difficult to retrieve from the bottom of the copper tube.
