What water pressure is required for this washing machine to operate correctly?

The proper water pressure for this washing machine is between 50 kPa and 800 kPa. Water pressure less than 50 kPa may cause the water valve not to close completely or may cause the drum to take longer to fill, which could cause the washing machine to turn off. Water taps must also be within 120 cm from the rear of the washing machine so that the provided inlet hoses can reach. (Page 16)
