AUTOMATIC ELECTRONIC DIAGNOSTICS

The faceplate timer (PWA) computer has a self- diagnostic function for the electrical system, except for input power and water meter. The computer

monitors

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 but-

ton. SELECT remains operational so the service per-

son can make the MANUAL INITIATED ELEC-

TRONIC DIAGNOSTICS (below) to further isolate the defect, and check the water meter.

WATER METER (A) SWITCH (B)

A. The first 3 digits indicate water meter operation as follows:

000 (steady) = Soft water not in use, and no

flow through the meter

--OPENA NEARBY SOFT WATER FAUCET--

000 to 199 (continual) = Repeats display for each

gallon of water passing through the meter.

If you don't get a reading in the display, with faucet 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.

The air purifiers also feature an automatic mode that adjusts fan speed based on the air quality detected through integrated sensors, providing optimal performance without constant manual intervention.

Another key characteristic of these models is their quiet operation. They are designed to run quietly, making them suitable for use in bedrooms and living spaces without causing disturbances. This silent performance does not compromise their effectiveness, and users can enjoy cleaner air while maintaining a peaceful environment.

Energy efficiency is an important consideration for any home appliance, and the Kenmore 625.38816 and 625.38815 models are no exception. Both units are ENERGY STAR certified, ensuring that they consume minimal energy while providing powerful air purification.

In conclusion, the Kenmore 625.38816 and 625.38815 air purifiers stand out for their robust filtration capabilities, user-friendly features, silent operation, and energy-efficient design.
