AUTOMATIC ELECTRONIC DIAGNOSTICS
The face plate computer has a self8diagnostic function for the electrical system (except input power and water meter). The
computer monitors the electronic components and circuits for cor8
rect 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. The SELECT button remains operational so the service person can make the MANUAL INITIATE ELECTRONIC DIAGNOSTICS to further isolate the defect, and check the water meter.

MANUAL INITIATED ELECTRONICS DIAG-
NOSTICS
1. To enter diagnostics, press and hold the SELECT button until 000 - - shows in the display.
A. The first 3 digits indicate water meter opera8 tion as follows:
000 (steady) = Soft water not in use, and no flow through the meter.
OPEN A NEARBY SOFT WATER FAUCET
