      LUCCA A53: Resetting the Safety Switch

      If your brew boiler (aka coffee boiler) fails to heat, here is the first step of troubleshooting to check if the over-temperature safety switch has been tripped.

      Tools required:

      • #2 Philips head

       

      Before continuing ensure the machine is fully cooled and unplugged from the power source.

      1. Remove the top panel.

      2. Identify the safety switch:
        a53_safety_brew_top
        a53_safety_switch
      3. Gently press down on the small red button to reset the switch. It may help to remove the wiring connections for better access:
        a53_switch_reset_01
      4. The button may not make a physical or audible click, but this procedure is still an important troubleshooting first step.
