Dishwasher Setup

Water Softening System

Your dishwasher requires soft water to ensure proper washing results and is equipped with an internal
water softening system. However, if you have a household water softening system, the internal system
provided is not needed.
For the water softening system to function properly, it will need to use the dishwasher water softening
salt. The amount of salt dispensed can be set from "H:00" to "H:07". Salt is not required at H:00 (this is
the default factory setting). The amount of salt required depends on the degree of hardness of your tap
water. See Table 1.
Turn the unit on using the [ON/OFF] button.

Using the water hardness test strip
Your water hardness level directly impacts your dishwasher's performance. Hard water will increase spotting and reduce detergent perfor-
mance. Some dishwasher models are equipped with a water softener that uses a special salt to adjust the water hardness to obtain optimal
performance. The dishwasher salt is added to the salt chamber located under the lower dishwasher rack. The amount of salt that is dispensed
is based on your home water hardness. The home water hardness can be determined by using the water hardness test strip included in your
manual set (or from your local hardware store). The dishwasher water softener setting must be adjusted to match your water hardness.
‡ Only use salt designed for automatic dishwashers. Never use household water softener salt or table salt.
‡ Follow the instructions below for the included test strip (If purchasing a different test strip, follow manufacturers instructions).
Step 1 - Run the water at the kitchen sink for 5 minutes.
Step 2 - Dip the end of the test strip with the colored squares into the tap water for 1 second and shake off excess water.
Step 3 - After one minute, compare the test strip to the chart below and determine the Dishwasher Water Softener setting.
Step 4 - Adjust the dishwasher Water Softener setting. Consult your Use and Care manual for details.
Step 5 - If required, add salt to the dishwasher salt chamber as shown.
