■ Press and hold the ADD SUPER WASH and PERMANENT PRESS buttons simultaneously.

When you check the water level, the first digit is a 0 which means 2.

actual frequency of 24.1 KHz.

■ Press the ADD SUPER WASH AND WHITES button simultaneously.

Under 200 rpm: The display indicates the rpm. (Under 200 rpm)
