What water pressure is required for the washer to operate correctly?

The proper water pressure for this washer is between 20–116 psi (137–800 kPa). Water pressure less than 20 psi (137 kPa) may cause the water valve not to close completely, or may cause the washer to take longer to fill and turn off. Faucets must be within 4 feet (122 cm) from the rear of the washer so that the provided inlet hoses reach. (Page 20)
