Panasonic microwave combi oven (Lee-on-the-Solent PO13)

The model number is NNCS89 and it is 4 years old. The steam and auto cleaning functions do not work. According to the repairers appointed by the warranty provider, there are no spare parts available, and this cannot be repaired. The microwave, convection and grill functions are fine and still work. It has been well used and is in need of a good clean. It is very heavy and may need two people to carry it. I am only putting this in here for a week, after which it’s going to recycling; it’s taking up too much space!
