Use craigslist if you are near a metropolitan area. No cost to you and you will get calls if the appliances are attractive and priced reasonably.

If you can't sell them on Craigslist then you are probably asking too much for them.

Watch for scammers and dodgers but chances are they will sell on CL without too much trouble.

If they won't sell, you can always donate them to a charitable thrift shop.

I sold my old fridge/washer/dryer all of which were on 4 years old and in great shape. New ones are pretty affordable so you won't get much. Price them to sell and you will get a lot of calls off craigslist.
