ECM Synchronika: Steam/Hot Water Valve Joystick Seal Inspection and Replacement

A leaking hot water tap or a steam wand that fails to dispense steam may be the result of an obstructed or worn joystick seal gasket.

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

Tools needed:

• 2.5 mm, 3mm, and 6mm Allen wrenches
• 17mm wrench
• New Joystick Seal Gasket

1. Start by removing the top and side panels.

2. Next, use the 2.5mm and/or 3mm Allen keys to remove the support bracket(s) as shown.

3. Use the 17mm wrench to unscrew the compression fitting holding the copper delivery tube to the valve.

4. Unscrew the 17mm retaining nut holding the hot water valve to the frame.

5. With the hot water valve removed from the machine, insert the 6mm Allen wrench into the back of the valve and remove the stainless fitting.

6. Remove brass and rubber seal gasket from valve. Make sure not to lose the spring.

7. Inspect seal and inside of valve for any debris. Remove debris. Inspect seal condition, replace if needed.
