AUTOMATIC ELECTRONIC DIAGNOSTICS

The face plate computer has a self7diagnostic function for the electrical system (except input power and water meter). The computer monitors the electronic components and cir7

cuits for correct operation. If a malfunction occurs, an error code appears in the face plate display.

The chart below shows the error codes that could appear, and the possible defects for each code.

While an error code appears in the display, all face plate buttons are inoperable except the SELECT button. SELECT remains operational so the service person can make the MANUAL INITIATED ELEC7 TRONIC DIAGNOSTICS (below) to further isolate the defect, and check the water meter.

PROCEDURE FOR REMOVING ERROR CODE FROM FACE PLATE: 1. Unplug transformer 2. Correct defect 3. Plug in transformer 4. Wait for 6 minutes. The error code will return if the defect was not corrected.

MANUAL INITIATED ELECTRONICS DIAGNOSTICS

1.To enter diagnostics, press the SELECT button and hold for 3 seconds.

You will see the following display, showing valve cycle position, position switch status (open or closed), and turbine operation.

indicator (open) turbine count (no water flowing)

TURBINE OPERATION: If no water is flowing through the softener, the turbine indicator displays 3 zeros. When water is flowing, the flow bar scrolls across the display, and a 000 to 199 count repeats for each gallon of water passing through the turbine. To check for positive operation of the turbine if zeros are shown, open a nearby soft water faucet and observe the turbine count and flow bar.

If you don￿t get a reading in the display, with facuet open, pull the sensor from the valve outlet port. Pass a small magnet back and forth in front of the sensor. You should get a reading in the display. If you get a reading, unhook the in and out plumbing and check the turbine for binding.

POSITION SWITCH STATUS: WIth the valve in service, or any of the recharge cycles, the switch

indicator will show open . While the valve is rotating from 1 position to another, the indicator will show the switch closed . A defect is probable if indications vary from this pattern.

625.34857, 625.34859 specifications

The Kenmore 625.34859 and 625.34857 are notable water filtration systems designed for residential use, offering an efficient way to ensure clean and safe drinking water. These units are characterized by their advanced filtration technologies and user-friendly features that cater to the needs of modern households.

One of the main features of these models is their multi-stage filtration process, which effectively removes contaminants such as chlorine, sediment, and various impurities found in tap water. The filtration system includes a sediment filter, a carbon filter, and a reverse osmosis membrane, working synergistically to improve water quality significantly.

The reverse osmosis technology is a standout aspect of the Kenmore 625 series. This method utilizes a semi-permeable membrane that allows only water molecules to pass through while blocking larger molecules and contaminants. As a result, users enjoy cleaner, better-tasting water free of harmful substances. The filtration process is further complemented by a post-carbon filter that enhances the taste and removes any remaining odors.

Another significant characteristic is the high capacity of these systems. With a storage tank that provides ample water supply, families can conveniently access filtered water whenever needed without the frequent need for cartridge replacements. The POU (Point of Use) design allows for easy integration into kitchen setups, making it an ideal solution for cooking, drinking, and food preparation.

Furthermore, the Kenmore 625.34859 and 625.34857 come equipped with monitoring technology that alerts users when filter changes are needed. This feature eliminates the guesswork, ensuring that the systems operate at peak efficiency and maintain optimal water quality.

Installation of these units is user-friendly, often requiring only basic plumbing skills, making it accessible for DIY enthusiasts. Additionally, both models are designed for low maintenance, offering long service life and reliability, which makes them an excellent investment for those looking to elevate their home water quality.

In summary, the Kenmore 625.34859 and 625.34857 are advanced water filtration systems that combine effective multi-stage filtration, cutting-edge reverse osmosis technology, high capacity, and user-friendly features. Their ability to deliver purified water consistently makes them a popular choice for families looking to improve their drinking water quality and ensure their health and well-being.
