What Samsung washer water pressure range should i set at?

To fill water into the Washing Machine correctly in recommended time period, the water pressure must be between 20 and 116 psi. 

Water pressure less than 20 psi can cause water valve failure or prevent the water valve from shutting off completely. 

A fill time limit is built into the controls of your Washing Machine. If your Washing Machine takes too long to fill in or has a leaking or ruptured internal hose, the Washing Machine controls will turn it off automatically. 

Water faucets must be within 4 feet (122cm) to accommodate the inlet hoses provided with your Washing Machine.
