Step 1: Power Down

Switch the coffee machine off. Yes, really switch it down. Don't just turn off the lights. You're not trying to be a rebel, are you?

Step 2: Inspect and Clean

Run your hands along the surface of the machine, searching for any visible debris. Don't worry, we won't judge you if you find a few stray grounds.

Step 3: Descale and Refill

Run the descaling cycle, then refill the machine with water. If this doesn't work, call in a professional... or just pretend to.
