I have a washer/dryer combo and the plug in the wall will not fit the plug on the machine. the machine has a four prong outlet and the wall has a three prong outlet, can i just change the one in the wall or do i have to change the outlet and the wiring and the breaker for a higher usage. I don't know what's the amp in the breaker is i would have to look. my guess what ever it is to run a washer

Which receptacle do you have on the wall and which plug on the combo?
