Krups Coffee Machine Not Heating

Expert guide to diagnose and fix "not heating" on Krups machines.

⚡ 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.

Frequently Asked Questions

Cold brew means the heating element, its thermostat, or the thermal fuse has failed. Scale builds up inside every coffee machine and eventually blocks the boiler and pipes. Run a full descaling cycle with Krups's approved descalant every 2-3 months (or whenever the machine prompts it), then rinse with fresh water. If your machine refuses to descale, see our Not Heating guide.

The quickest way to fix scale problems on a Krups is a full descaling run: use the approved descalant, follow the machine's cycle, and finish with two rinse brews. Repeat every 2-3 months, or as soon as the alert appears. Step-by-step instructions are in our Not Heating guide.

If a Krups has not been descaled for a while, limescale restricts the boiler and pipes. Buy the brand's descalant, run the descale program, rinse thoroughly, and schedule it every 2-3 months from now on. See our Not Heating guide for the full routine.

A Krups prompts for descaling based on water hardness and usage. The fix is simple: run the descale cycle with approved descalant, rinse twice, and use filtered water to make the intervals longer. Details in our Not Heating guide.
