26 Miracle Water Installation & Operation Manual
Automatic Electronic Diagnostics
The faceplate has a self-diagnostic function for the electrical system (except input power and/or water
meter). The faceplate monitors electronic components and circuits for correct operation. If a malfunc-
tion occurs, an error code appears in the faceplate display.
The troubleshooting chart on page 26 shows the error codes that could appear, and the possible
defects for each code.
While an error code appears in the display, all faceplate buttons are inoperable except the
SELECT/MENU button. SELECT/MENU remains operational so the service person can perform the
Manual Advance Diagnostics, see below, to further isolate the defect.
Manual Advance Diagnostics
Use the following procedures to advance the unit through the regeneration cycles to check operation.
Remove the Faceplate Cover to observe cam and switch operation during valve rotation.
1. Press and hold (Select/Menu) for 3 seconds until 000 --shows in the display. SELECT
MENU
2. The first 3 digits indicate water meter operation as follows:
000 (steady) = Soft water not in use, and no flow through the meter.
—OPEN A NEARBY SOFT WATER FAUCET —
000 to 199 (continual) = Repeats display for each gallon of water passing through the meter.
NOTE: 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.
3. The letter (P) and dash (or dashes) indicate POSITION switch operation. If the letter appears, the
switch is closed. If the dash shows, the switch is open.
4. Use the Recharge button to manually advance the valve into each cycle and check correct
switch operation.
