What should be cleaned a lot more often

Tips: Descale the coffee machine properly

Guide to fully automatic machines & Co.

If you value the best coffee taste, you shouldn't forget about regular maintenance of your machine. Here are a few tips on how to descale and clean fully automatic machines and the like.

When should it be descaled?

At the latest when you notice that the water is coming out of your coffee machine more slowly than usual, the temperatures are too low or no proper crema can be produced, it is time to act. Under no circumstances should you wait until flakes of lime float in the coffee, the pump makes unnatural noises or the machine completely blocks. The good news: some models - such as the EQ line from Siemens - have a self-cleaning function. For all other coffee machines, we have some tips here on everything to do with descaling and cleaning.

Decisive influencing factors

How often the coffee machine needs to be descaled depends on the hardness of the water (the harder, the more often it has to be cleaned) and the flow of water (i.e. how much coffee is drunk). For big coffee lovers, it means cleaning the machine every two to three weeks. As a rule of thumb, dedicate yourself to maintenance every one to two months.

Use special descaling agents

They are recommended by the respective manufacturer and gently remove limescale deposits that can have a negative effect on the water supply and heating times. There are decalcifying agents in liquid and powder form, which are mixed according to the instructions. After the limescale has been flushed out, clear water should still run through the machine in order to avoid detergent residues and possible foreign tastes in the freshly prepared coffee.

Are vinegar and citric acid recommended for cleaning?

Manufacturers do not recommend using vinegar, vinegar essence or citric acid, as the acid can damage the rubber seals or not completely remove all deposits. Filter coffee machines without a pump can be cleaned with vinegar essence if you want to use natural cleaning agents. Citric acid may only be used for cold decalcification, if at all, as a sticky mass forms when heated and is deposited in the machine. It is therefore not advisable for fully automatic machines, capsule and pad systems.

Check operating instructions

Take a look at the operating instructions for your coffee machine. Newer models usually indicate when it is time to descale. A certain amount of brewing processes serves as the basis for calculation. If it is possible to save the water hardness individually, it should be used to determine an even more precise point in time. The cleaning and descaling programs are then started at the push of a button or the app.

Convert to a modern coffee machine

The latest generations of fully automatic machines, such as the EQ line from Siemens, offer automatic programs for daily cleaning and automatic decalcification at optimal intervals. Blocked supply lines and hoses are a thing of the past.
