Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.
The best thing you can do is put power surge protectors on these, they sell in that plug-in for the washer but for the dryer you would need to buy the one that goes in the breaker box, they have special 220 breakers that are similar to GFI breakers and if something goes wrong with the power or you get a Spike or a surge it will kick off before it gets to your dryer, this is something however that should be done by an electrician, they have access to these and is also in your main power box which it's not a good idea for you to be playing around in less your an electrician, that's what I would suggest for you, thanks, Bryan
I was told that such surge protectors do not exist for 220. Live and learn. Before I push the green accept button, can you tell me if Edison's evaluation is a valid possibility, even though the dryer was turned "off"?
Thanks for your help and your $30 will be on the way when I get your reply.
