How do you descale a built-in coffee maker?

Why descaling your built-in coffee machine is essential

This is how you keep your coffee machine in top condition and your coffee flavorful. Every coffee lover naturally wants to enjoy a perfect cup of coffee, day in, day out. But did you know that limescale is one of the biggest culprits when it comes to flavor loss, malfunctions, and even permanent damage to your coffee machine? Regularly descaling your built-in coffee machine is therefore crucial, not only for the taste but also for the lifespan of your appliance.

Why does limescale build up in your coffee machine?

Water is essential for coffee. But water also contains calcium and magnesium, which cause limescale to form when heated. This limescale adheres to pipes, the heating element, and other parts of your machine. Over time, this can lead to reduced water pressure, slower flow times, and even pump or boiler failure. The taste of your coffee also changes: bitter, bland, or lukewarm. So descaling isn't just maintenance; it's essential for optimal performance and coffee quality.

How to descale your built-in coffee machine in 4 easy steps

1. Use the correct descaling agent

Always use the recommended Descaling agent from your coffee machine's brand. This prevents damage to sensitive components. Don't use vinegar! This may seem like a quick fix, but it can damage the rubber seals and even cause irreparable damage.

2. Start the automatic program

Almost all built-in coffee machines have an automatic descaling program. You can start the program via the display or the menu. The machine guides you step by step: all you need to do is add the descaling solution to the water.

3. Rinsing is essential

After descaling, the machine usually rinses automatically with clean water. Check that the rinsing process is complete. If in doubt, rinse again manually to remove all residue.

4. Repeat in time

Don't wait until your coffee tastes worse or your machine runs slower. Make it a habit to descale every few months. In areas with hard water, it may even be necessary to do this monthly.

Extra tip: use a water filter

Want to minimize limescale buildup? Use a water filter if your coffee machine offers one. This filters a large portion of the limescale from the water before it enters the machine. This improves your coffee's taste and reduces the need for descaling. It's also useful if you live in an area with hard tap water.
