Home water pressure should be 20 to 120 psi for proper dishwasher fill. A booster pump on the water supply may be neces- sary if pressure is too low.

Never use soap or laundry detergents. Use recommended dishwasher detergents only.

Conditioning the final rinse water with a liquid rinse agent helps eliminate spotting and filming. Keep the dispenser filled with a rinse agent at all times.
