Frequently Asked Questions

Why is my KitchenAid machine overheating?

Overheating is usually scale insulation on the boiler or a stuck thermostat. Scale builds up inside every coffee machine and eventually blocks the boiler and pipes. Run a full descaling cycle with KitchenAid'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 Overheating guide.

My KitchenAid Kcm111 gets too hot — is it dangerous?

The quickest way to fix scale problems on a KitchenAid 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 Overheating guide.

How do I fix overheating on a KitchenAid coffee machine?

If a KitchenAid 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 Overheating guide for the full routine.
