Our Neff microwave model no E-Nr B7740N0GB/02 FD(###) ###-####
The microwave seems fine, all lights operate normally, all controls operate normally including the stop button which feels good.
But none of the systems will start because of the start button which feels very spongy. No matter how gentle or hard the start button is pressed, it will not action any of the operations. This failure had been getting progressively worse over many weeks until it failed completely.
The microwave is about 11 years old but seems in very good condition except for the fault. It has had very little and light use
