Steam Boiler Maintenance

LUCCA A53 / Vivaldi: Steam Temperature Probe Removal

Below are photos and a video for removing the steam boiler temperature probe on a La Spaziale Vivaldi or LUCCA A53 espresso machine.


Temperature probes can often cause issues with steam boilers over-heating or not heating at all. Both of these outcomes will cause a blocking alarm to appear on the control panel of the machine that communicates when the steam boiler has been attempting to reach operating temperature for too long. Before the probe can be removed the side and back panels need to be removed. Also, before attempting to replace the steam boiler temperature probe we recommend verify that all the wire connections are firmly plugged in and providing power. The first two photos depict the wires to check, if everything looks to be working well then we recommend replacing your temperature probe.
