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

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 take longer to fill the drum, causing the washer to turn off. Water taps must be within 4 ft. (122 cm) from the rear of the washer. (Page 12)
