What water pressure is required for the WAW285H1 to operate properly?

The water supply pressure must be between 14.5 to 145 psi (1–10 bar) with a minimum flow of 2.2 U.S. gallons (8 liters) per minute. A pressure regulator valve must be installed if the maximum water pressure is exceeded. Only use the new AquaShield water supply hoses included with the washer, and never reuse old hoses.
