LUCCA A53 Mini / Mini Vivaldi: Inspecting Inlet Tubing

These instructions demonstrate removing the flexible inlet tubing from an A53 Mini and Mini Vivaldi for inspection, cleaning, or replacement. (Difficulty ☕☕)

Tools Needed:
- 17mm crescent wrench or adjustable wrench
- Small snips or scissors
- Flathead screwdriver

1. Remove the panels. You'll need to access the machine through the back panel.

2. Use the 17mm crescent wrench to remove the brass fitting from the inlet coupler elbow. Carefully snip the zip tie attaching the inlet tubing to the expansion valve.

3. Remove the inlet tubing from the pump inlet barbed fitting, The coiled spring acts as a hose clamp, securing the inlet tubing to the barbed fitting and preventing leaks; you will need to "unscrew" the spring from the barbed fitting before pulling off the tubing.


4. Remove the inlet tubing from the expansion valve. You can use a flathead screwdriver to gently pry, while pulling the inlet tubing at the same time.


5. Snip the zip tie securing the inlet tubing to the bottom of the machine.

6. You can now remove the inlet tubing from the machine. Inspect for obstructions or tears. Flush with water and mild soap to clean. Replace if necessary.
