to be clear here, washers are generally 120 volt, under 15 amps. dryers however can be 120 volt or 240 volt. if 120 volt they are typically under 20 amps. If 240 volt they are typically ABOUT 30 AMPS or slightly less,.....but can be as much as 50 AMPS. the larger draw 240 volt dryers will have a DIFFERENT PLUG per industry standard and require appropriate wiring. changing the plug to fit an underpowered circuit will result in circuit breaker flipping off or possible fire hazard.
