Heater runs about 5400 watt. Motor pulls about 500.
How much of the cycle the heater runs would depend on the amount of clothes, type of clothes, how well the washer spins out and how clean the vent and lint screen are.
You could get an amp clamp and check to see if your pulling more then you should be. One leg should be around 20 amps or a little lower and the one with the motor on it should be a few amps higher.
