LUCCA A53 / Vivaldi: Coffee Boiler Element Replacement

Below you will find step by step instructions for replacing the coffee boiler element on a La Spaziale LUCCA A53, A53 Mini, Vivaldi II, or Mini Vivaldi II espresso machine.

Tools Needed:

  • Phillips screwdriver
  • Crowbar
  • Mallet/hammer
  • 5mm Allen Wrench
  • Silicone sealant

1. Remove the panels of the machine.

2. Drain the coffee boiler of the machine.

  • For Minis, follow our instructions here.
  • For plumbed in units, close the water line, run the coffee boiler until no water is coming out. There will be water that will leak out of the boiler, so a towel will be useful to keep it from going everywhere.

3. Unplug the coffee boiler element and disconnect the temperature probe wires from inside the orange sleeves.

4. Using a crowbar and a mallet, carefully knock the collar loose (counterclockwise). Once it breaks free you should be able to unthread it with your hand. The coffee boiler is securely mounted to the frame of the machine, you will find the most important part of this step is making sure the crowbar stays in place when striking it as the boiler itself will not move.

5. Remove the silicone plug and pull out the temperature probe. Once the silicone sealant is out, use a 5mm wrench to remove the temperature probe sleeve out of the element.

6. Swap the gasket on the inside of the element, or install a new one if necessary. Reassemble element and tighten down collar, using the crowbar and mallet to make sure it's snug. Reseal the the temperature probe with silicone sealant once the temperature probe sleeve is back in the element.
