Bosch SHE7PT52UC Operating Instructions Manual page 15

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.
Instructions for use of included "Water Hardness Test Strip"
‡ 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.

Using the Test Strip included with your dishwasher
(Purchased Test Strips May have a Different Scale)
Refill the salt container, using a funnel to pour,
right before turning on the unit to ensure that
salt overflow is immediately washed away. This
prevents corrosion. See Figure 11.
1 Open the screw cap of the salt container.
2 Fill the container with water (only required
when turning on the unit for the first time).
3 Add dishwasher salt until the was is dis-
placed and runs out.
4 Refill with salt as soon as the salt refill indicator is lit.
Warning: Never fill the salt dispenser with detergent. It will destroy the
water softening system. To prevent corrosion, refill with salt and imme-
diately begin any cycle.
Note: Refill salt only when the "Refill Salt" LED or the salt refill symbol is lit
(model dependent).
Do not use salt tablets or any salt other than dishwasher water softening
salt.
For more information about ordering salt please contact Customer Service.
