I also have a Philips HD3039 multicooker, and I’ve been using it for about two years now. As for cleaning the bowl, the main thing is not to use hard sponges so as not to damage the non-stick coating. I clean it with a soft sponge and warm water, and this is usually enough. It is also important not to leave food in the bowl for a long time, especially if the dish is milky or contains fat. If you need any clarification on the operation, look at the manual here: Brother LB6800 [53/172] Starting to sew . The multicooker is excellent, the main thing is proper care, and it will last a long time!
