Lucca M58: Steam/Hot Water Valve Joystick Seal Inspection and Replacement
A steam/hot water wand that constantly drips or fails to open/close consistently often indicates a compromised joystick seal gasket. (Difficulty ☕☕☕☕)
Tools Needed:
- 17mm crescent wrench
- 17mm deep socket and ratcheting wrench
- 6mm Allen key
-Highly recommended: bench vise
1. Start by removing the panels from the machine.
2. Use the 17mm crescent wrench to unscrew the brass compression fitting from the hot water or steam assembly inside the machine. You may need to disconnect the other end of the copper delivery tube from the boiler to get better access to the hot water/steam assembly.
3. Use the 17mm deep socket and ratcheting wrench to remove the extension adapter from the hot water or steam arm.
4. Use the 17mm deep socket and ratcheting wrench to remove the retaining nut from the hot water or steam arm. You can now pull the hot water/steam arm free from the machine.
5. The inside of the steam arm has a built in hex-fitting. Insert the 6mm Allen key and use it to unscrew the joystick cap from the hot water/steam arm.
6. Pull out the joystick seal gasket for inspection. Clean or replace as necessary.
7. Follow these instructions in reverse to reassemble the hot water/steam arm assembly and re-install it into the machine.
