Question about Siemens iQ300 SN63EX02AE

Warranty information
If a product is faulty and there is a warranty claim, the first thing to do is check your customer account. In the customer account, under "Orders", you will find all the information relating to the guarantee, such as the date of purchase, the duration of the guarantee, the service centre and the procedure to follow in the event of a guarantee claim. To ensure a smooth process, in the event of a warranty claim, it is necessary to register the fault in the online shop via the order or via "Returns and faulty products". There you will find all the information you need about the returns process.

If examination of the product reveals that repair of the fault is not covered by the warranty, you may request an "out-of-warranty repair" at your own expense. If you decline, the unrepaired product will be returned to you or disposed of. You may be charged for any costs incurred in testing the appliance.

Good morning, in case of faults and problems there is the Siemens service department which is covered by the warranty for two years.
Once the warranty has passed there are various companies just about everywhere for appliance repairs and services.
I for example have a business and do this for Ticino (Lugano - Mendrisiotto)
