What are the water pressure requirements for connecting the washing machine?

The water pressure in the mains supply should be between 50–900 kPa (0.5–9 bar), which equates to at least 8 litres of water flowing out per minute when the tap is turned on. If the water pressure exceeds this range, a pressure reducing valve must be installed. Only cold drinking water should be used, and the machine must not be connected to the mixer tap of an unpressurised hot-water boiler. (Page 26)
