As others have said, unlikely. To try to give you a bit of an explanation for this. Unless you have fancy electronic controls, an oven is what we call a resistive load, and resistive loads will happily run from all sorts of odd wave forms and frequencies. A washing machine, these days, has a lot of complex electronics and computer(s) to control the motors and the main motor may well be very different to the common types to allow for reversing and speed control. It is the electronics that seem to get upset by a frequency or waveform that is not spot on., so unless you have a very fancy oven with electronics or computer control it should work. All sorts of electronic devices may have potential problems with inverters, especially non-sine wave ones, so often it is try it and see.
