Steam Boiler Maintenance

Lelit Elizabeth: Testing the Steam Boiler Safety Switches

Does the steam boiler on your Elizabeth fail to heat? A tripped safety thermostat aka safety switch could be the culprit. Below are instructions for resetting the safety switch and testing for continuity. (Difficulty ☕☕)

Tools needed:

- T20 Torx driver
- Small flathead screwdriver
- Multimeter or simple continuity tester

NOTE: The machine should be unplugged and cool to the touch before beginning.

1. Remove the top panel.

2. Identify the two safety switches on top of the steam boiler.

2. Carefully use a finger or small flathead screwdriver to gently press down on the rectangular button in the center of the safety switch, making sure it is fully depressed. Feeling a slight "click" when pressing this button indicates that the switch was tripped.


Testing the Safety Switches:

If the buttons don't appear to have tripped, but the steam boiler still fails to heat, test for continuity across the safety switches. Touch one probe from your multimeter or continuity tester to each of the two spade connectors on both safety switches. A lack of continuity, even when the center button is fully depressed, indicates a faulty safety switch; replace as necessary.
