Over-voltage damage

In late summer, the house of my mothers' girlfriend suffered damage to the incoming main power line. The neutral line broke and shorted to one of the legs, resulting in the entire house receiving 220V instead of 110V. The damage was really random, but the major appliances damaged was a microwave and this GE washer.

I assume the main computer board was fried and I can get a replacement, but I've hesitated to do so if the motor / pump was also destroyed by the over-voltage. I looked briefly at the motor and pulled the rather complicated harnesses from it, but saw no obvious damage.

Is there a simple method to test this motor or what is the opinion of everyone here - worth the effort or just scrap the whole machine?

I'll take advice on the microwave too.

Heartfelt thanks for any advice.
