Care Of Your Water Softener

CHECKLIST TO HELP YOU SAVE MONEY
If your water softener fails to work, make the following easy checks. Often, you will find what is wrong yourself and
you won't have to call and wait for service. If you do not find anything wrong, while making the checks, and your sof-
tener still does not work, call your Sears Service Department.
1. Also read ERROR CODE.
2. If an error code is not displayed, press and hold the SELECT button until the display changes. Then, press the
SELECT button again and hold until a flashing code appears. It must show H46 for Model 38426 or H47 for model
39426. If any other number shows, the face plate computer is working on incorrect input and would probably be
the cause of the problem. To set the correct code, press either the UP or DOWN button. When correct model
code shows, press SELECT to return a flashing 12:00 AM display. Reset the present time, hardness number, etc.

and correct. With the power back on, look at
the time display and read PROGRAM MEMO-

Look at Fig. 18 & 19 on page 15. Move the
stem in a single valve to service. In a 3-valve

sure to fully close the bypass valve.

bends, or be raised too high above the soften-
er, see page 14.

hardness number in the display and be sure
the same grains per gallon number is shown
as on your water analysis report. See page 18

Avoid using hot water during this time because
the water heater refills with hard water, see

Ask your Sears retail store for a new water
analysis. Then make a new hardness number
setting, page 18.
