How much water pressure does dishwasher need?

Dishwashers generally require a water pressure between 20 and 120 psi (pounds per square inch) for optimal performance. If the water pressure is too low, the dishwasher may not be able to function properly, resulting in poorly cleaned dishes. On the other hand, excessive water pressure can cause damage to the dishwasher and its components.

It's important to check the water pressure requirements specified in the owner's manual of your particular dishwasher model. If the water pressure in your home is too low or too high, you may need to adjust the pressure regulating valve or install a pressure booster pump to ensure proper water flow to the dishwasher.
