⚡ TL;DR — Quick Answer

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

What Causes Not Heating?

Saeco super-automatics feature removable brew groups that must be rinsed daily.

Step-by-Step Fix

Follow these steps specifically for Philips Saeco machines:

  1. Descale the Philips Saeco boiler using an approved descalant. Limescale is the #1 cause of heating failures.
  2. Test the NTC temperature sensor with a multimeter. On Philips Saeco 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.
