When we bought the house we are living in now, we got a home inspection and a warranty.
The home inspector said the dishwasher was “serviceable.”
Six months later the dishwasher rusted through.
The warranty company sent their rep out and he said it was a “preexisting condition” so the warranty company refused to pay.
It was the same guy.
We also had a problem with the door on the oven which was unrepairable since parts were not available and they refused to pay for that either.
My wife did the paper work and served them for small claims court. They offered half the price of new appliances which we took before actually going to court.
We actually did benefit from the insurance but only because we lost two major appliances in a year. If it had only been one we would have been break even with a big hassle getting them to pay. I probably wouldn’t buy the insurance again.
