Plugged in 220v by mistake

This equipment has an internal fuse to protect the power supply transformer. Most probably it is burnt out.

most likely fried circuits and look in area for repair shop why trying to ship to us to fix

There is an over-voltage protection fuse, but, it is inside the transformer. It can be replaced by experienced service technician. Contact any one such.

An stepdown transformer is needed should you buy in US and use it Europe

However, if your on a technical side , trace the primary windings , and check

There are European versions which are already 220V, no need to convert.

If the dryer is electric and bought in the United States then you can plug it in. The 110/220 power rating basically means that some parts if the dryer use 110v. All 220v is is 2 110v independent circuits sharing the same common ground.

You will have more available power (and use a different larger breaker already on your generator) if you use the 220 plug instead of the 115v plugs. Have an electrician make you an breakout box separating the 220v plug into two 115v outlets. Or your can replace the push button breakers with better quality 25 amp. Problem is that the 115v receptacles are probably 15 amp. Other solution is to try a 220v pump instead of 115v (more efficient draws less amps). Good luck

If you want to fry your electronics or appliances that's it's a sure way to accomplish that.
While appliance working ONLY at 220v will just not work or under perform (like a hair drier) when plugging electronic equipment that runds ONLY at 110v then that item will be "fried" as all its electric components will be burnt as it will receive twice the power that it was build to receive. Should that happen the safety switch on the 220v circuit where the item was MISTAKENLY plugged will be triggered (hopefully or there will be risk of fire and serious injuries, even death) and the power will be shut off. That's a major but possible mistake.
If traveling abroad those who come to US will unlikely damage their appliances (like electric razors) as they will receive less power (110v vs 220v) and usually these items are protected against these mistakes by the specifications of their own design. The opposite is not true of course as just mentioned above.
So do not play around with dangerous items please! ;) On a positive note though: Nowadays most appliances have dual power and should work whether plugged in a 110v, 60Hz (most common in US) or 220v 50Hz (most common in Europe). So nothing really happens... it just works as long as you have the proper adapters to plug the appliance to the different receptacles.
Note: One of the differences is that (without going into the math of it all), an appliance working at 110v will draw x2 times the power than it draws when working on 220v so if an appliance was drawing 3A at 110v it will only draw 1.5A when working at 220v.
Best.

i did the same thing when i was over seas, damn 220v, and all it did was blow the fuse in the unit, if you have an inline fuse (along the power cord) it might have blown there, if not you will have to take the unit apart and change the fuse, might be soldiered on the circuit board but its a relatively easy fix, just hope that the board itself didnt get shorted out, if so you will need to replace the system, i used this website when i was overseas and all my stuff got to me with in 10 days...

I don't know for sure, but I suspect that if you open it up, there should be a fuse near the power supply portion of the unit. It may have taken the hit for you and can perhaps be replaced easily. (As a disclaimer... be sure the unit is not plugged in when you open the case! And only replace the fuse with another of equal rating.) If it's not a fuse, then you probably smoked the primary winding of the transformer. If it got past that, you may have popped the rectifier and/or capacitor(s) in the power supply.
