In the detergent drawer, you have to pour the descaler carefully. The dosage depends on the product that you choose. I suggest you always stick to the dose labeled on the descaler’s package. 

If you choose a homemade alternative as a descaler, like soda, or white vinegar, you can use as much as you prefer. Remember that a store-bought descaler will give you the best results.

After all, the product is created solely for cleaning purposes.

Run a wash cycle 

Now you need to start a washing cycle, preferably at 140 °F. You can start a washing program at 104 °F, but 140 °F gives the best results. 

An important thing here to remember is that regardless of the temperature, you need to start the cycle without a pre-wash. 

Also, you must leave the washer to run the cycle until the end. If the program is interrupted, the machine cannot be properly cleaned.

Run the same cycle 

After the first washing cycle with the descaler ends, the chances are there is still some powder left in the washer.

To empty the drum, you must rerun the same program without a descaler.
