⚡ TL;DR — Quick Answer

Descale the Krups boiler using an approved descalant. Limescale is the #1 cause of heating failures.

What Causes Not Heating?

Krups machines combine durable grinders with programmable brewing options.

Step-by-Step Fix

Follow these steps specifically for Krups machines:

  1. Descale the Krups boiler using an approved descalant. Limescale is the #1 cause of heating failures.
  2. Test the NTC temperature sensor with a multimeter. On Krups machines, a faulty sensor shows infinite resistance.
  3. Inspect the heating element for calcium deposits. If resistance is out of spec, replace the element.
  4. After descaling, run 3 empty brew cycles to purge air from the heating chamber.
