📹 ECM Elektronika II Profi: Steam Boiler Not Heating, Not Steaming or No Hot Water At All

Learn what to do when the steam boiler in an ECM Elektronika II Profi espresso machine is not heating, not steaming, or will not produce hot water at all.

Confirm that water is coming through the group head when the volumetric button is pressed, and that this has been isolated to a steam boiler issue. You can still get water out of the group head without the boiler being full. Make sure the autofill function has successfully filled the boiler. The easiest way to do this is to remove the probe from the autofill and let it run for a few seconds while watching the level in the tank. See if it starts to drop. Put probe back on. Do not run this for too long or you will overfill the boiler and water will pour from the safety.

      • Yes. Move on to the next question.
      • No. Replace the high limit switch.

NOTE: While the video below features the Profitec Pro 700, the ECM Elektronika II Profi is set up similar enough that following the instructions will provide the same result. The only significant difference between the two machines is the orientation of the boiler on the Elektronika II Profi.
