What water pressure is required for the Samsung washing machine to work correctly?

The washing machine requires a water pressure between 0.05 MPa and 0.78 MPa (0.5 to 8.0 kg·f/cm²). Water pressure lower than 0.05 MPa may cause the water valve to malfunction and may extend the fill time beyond what the machine's controls allow, potentially causing the machine to shut off. (Page 16)
