The required water pressure for a portable dishwasher typically ranges between 20 to 120 pounds per square inch (psi). This pressure range ensures that the dishwasher operates effectively and cleans dishes efficiently. Most portable dishwashers can function adequately with a standard household water pressure of around 40 to 60 psi, which is commonly found in residential water systems.
It's essential to check the manufacturer's specifications and guidelines for the specific portable dishwasher model you have or plan to purchase. The user manual or product documentation should provide the recommended water pressure range to ensure optimal performance and avoid potential damage to the appliance.
