Samsung dishwasher water supply requirements
Before you install, or even buy your dishwasher, make sure the water supply in your home meets the requirements for water temperature, water pressure, and hardware for proper connections. The dishwasher's main method of cleaning your dishes is completely based on the water temperature and pressure, so if they don't meet requirements, you won't get the cleaning performance you expect. Check out what the requirements are for your dishwasher's water supply.
Caution: To avoid severe burns, the water temperature should not exceed 149°F.
Materials and requirements
It’s important that you review a few requirements before purchasing and installing your dishwasher, such as the water temperature and water pressure.
Supply line: The supply line is not included with the dishwasher but can be purchased at most hardware stores, including Lowes or Home depot. Most plumbing supply stores sell water supply lines of various lengths up to 10 feet long. A stainless steel supply line is recommended. If there is an issue with your supply line, you may experience error codes or blinking lights on your dishwasher.
Water temperature: A hot water supply of 120 - 149°F is required for the best cleaning and drying performance. If the water temperature is not consistent, you may experience error codes or blinking lights on your dishwasher.
Water pressure: The water supply pressure must be between 20 and 120 psi (pounds per square inch).
Note: Water pressure less than 20 psi will cause water supply valve failure and prevent the water supply valve from shutting off.
Elbow: A 90-degree elbow is not included with the dishwasher but can be purchased. It is required to connect the water line to the dishwasher. The elbow is 1/2-inch NPT (National Pipe Thread Taper) on one end, and 3/8-inch compression fitting on the other end.
For more information on materials and requirements, check your installation guide.
