How to Clean a Coffee Machine?

Published in Coffee Machine Cleaning 2 mins read

Cleaning your coffee machine regularly is essential for optimal performance and taste. Here's a guide on how to properly clean your coffee maker, incorporating descaling methods:

Regular Cleaning Steps

To keep your machine in good working order, perform these regular cleaning tasks:

  • Daily:
    • Rinse the carafe, filter basket, and any removable parts after each use. This prevents coffee residue buildup.
    • Wipe down the exterior of the machine with a damp cloth.
  • Weekly (or bi-weekly):
    • Wash removable parts with warm, soapy water.
    • Thoroughly clean the spray head/nozzle to prevent blockages.

Descaling Your Coffee Machine

Descaling removes mineral buildup (often from hard water) that can affect your machine's brewing efficiency and the taste of your coffee. Here's how to descale using vinegar:

  1. Prepare the Solution:

    • Remove any filters and coffee grounds from the machine.
    • Fill the water reservoir to its maximum level using a mixture of half white distilled vinegar and half fresh water.
  2. Run a Brew Cycle:

    • Start a normal brew cycle with the vinegar solution.
    • Allow the cycle to complete.
    • Empty the carafe once the cycle finishes.
  3. Rinse Thoroughly:

    • Fill the reservoir with fresh, cool water.
    • Run 2-3 more brew cycles with fresh water, emptying the carafe after each cycle. This removes any remaining vinegar residue.
  4. Final Check:

    • Check the water clarity and taste the water if necessary, to make sure all the vinegar has been removed.

Why Descale?

  • Better Taste: Mineral buildup can impact the flavor of your coffee, leading to a bitter or off taste.
  • Improved Performance: Scale can clog your machine, resulting in slower brew times or inconsistent water flow.
  • Extended Lifespan: Regular descaling can prolong the life of your coffee machine.


Task Frequency Method
Rinse Components Daily Warm water rinsing
Clean Components Weekly or Bi-weekly Warm soapy water washing
Descale with Vinegar As needed, 1-3 months (depending on water hardness) Half vinegar, half water solution
Rinse after descaling As needed Multiple fresh water cycles


Following these steps will help you keep your coffee machine clean and in excellent condition. Remember, you may need to adjust the descaling frequency based on your water hardness.
