How to descale your AEG steam oven

Last updated 21/02/2024 13:22

Pouring descaling fluid into water tank of steam oven Descaling your AEG steam oven regularly will ensure it continues to function properly. Limestone residue tends to build up over time to clog the system, which ultimately affects the oven’s performance. Our steam ovens send out a convenient descaling alert to remind you to descale your oven when needed. When this happens, you will receive a notification to run the Descaling programme that removes the limestone build-up.

Different oven models may contain different cleaning functions to facilitate the cleaning task. Refer to your oven manual to explore which functions you have to make cleaning your oven easier.

What is Descaling, why and when should you do it?

The Descaling function removes and prevents limestone build-up in your oven’s steam system, allowing it to continue to perform optimally.
Descaling needs to be done continuously – the frequency will vary depending on the amount of steam cooking you do. Also, the water hardness in your local area will affect the speed of the limestone building up.

The oven will alert you when it is time to descale. Make sure to descale your oven as soon as possible upon receiving the notice. Otherwise, it will affect the operation of steam functions, making it impossible to cook with steam until the oven has been descaled.
