DISPLAY FAULT MODE

DISPLAY FAULT Mode can be accessed by pressing and holding the ”Enter” button for 3 seconds. A two-tone sound will be heard, indicating the action was successful. Critical Faults will be displayed to user without entering Fault Mode (normal consumer operation mode). Note that control must first be awake to enter this mode, (press any button to awake control, illuminating the 7 segment LEDs, showing set point temperature). Control display will scroll through all active faults in Fault Mode (both critical and non-critical Faults).
Faults can be cleared, in Fault Mode by pressing and holding the “+” and ”-” buttons simultaneously for 3 seconds. A two-tone sound will be heard, indicating the action was successful. Faults will return, if condition triggering faults reoccurs. Exit Display Fault Mode by pressing “Enter” key or after 1 minute of button inactivity.

MONITOR MODE / LOAD STATUS
Monitor Mode can be accessed by pressing and holding the “+” and ”Enter” buttons simultaneously for 5 seconds. Note that control must first be awake to enter this mode,
(press any button to awake control, illuminating the 7 segment LEDs, showing set point temperature). A two-tone sound will be heard, indicating the action was successful. A
moment later, the control will display the Software Version. Press the “+” or “-” key to move between, T1, T2,T6, T7, Mixing Valve Position (if equipped) Voltage, Current, WiFi Strength, % Anode Life remaining (if equipped) and Personalities. The item ID will first display and then the display will list values. Exit Monitor Mode by pressing the Enter key or after 15 minutes of button inactivity.

  If equipped (sensing anode)

SERVICE MODE – ID:

When in Monitor Mode, Service Mode can be accessed by pressing and holding the “+” and ”Enter” buttons simultaneously for 5 seconds. A two-tone sound will be heard, indicating the action was successful. The control will display “SEr” to indicate the control is now in SERVICE mode. Press the “+” or “-“ keys to select the desired component to control. Hit the “Enter” key to toggle control of the selected component. When controlling the upper or lower heating element, the display will first show “UE0” or LE0, indicating that the UE or LE is OFF (signified as 0). The display will then show the current draw (in Amps), followed by “A”. Pressing the “Enter” key, will turn the respective element ON (signified as 1), displaying “UE1” or “LE1”. The display will then show the current draw, when the element is energized. Note that only one element can be energized at a time, so turning ON a second element will turn OFF the first element.
When controlling the mixing valve, the display will show “tSt” and will then indicate the test position of “Hot” (indicating the normal operating position, set by the control).
Pressing the “Enter” key will then move the mixing valve to the full cold position (displayed as “Cld”). Pressing the “Enter” key repeatable, will toggle the mixing valve +between the “Cld” and “Hot” positions. Exit Service mode by pressing “+” or “-“ keys until “SEr” is displayed and then press “Enter” to exist Service mode, returning to
Normal Operation. Note that in Service mode the selected heating element will remain ON for 5 min. and will then turn OFF. Upon exiting service mode or after 15min. of
inactivity, the control will revert back to normal operation mode.

to select component. Press “Enter” key to turn element ON (1) or OFF (0). Once ON, the current draw will be shown on display, signified as “A” for Amps. The heating element will turn OFF after 5 min., or when turning LE ON, or upon exiting Service Mode.
Lower Element| | Lower Heating Element (LEO=OFF; LE1=0N). Press “+” or “-” key to select component. Press “Enter” key to turn element ON (1) or OFF (0). Once ON, the current draw will be shown on display, signified as “A” for Amps. The heating element will turn OFF after 5 min., or when turning UE ON, or upon exiting Service Mode.
Electronic Mixing Valve| | EMV Test (CLd = full cold; Hot = Normal Control position). Press “+” or ‘=” key to select component “tSt”. Press Enter key to toggle control between “CLd” and “Hot” position. Mixing valve returns to normal operating state after 5 min. or upon exiting Service Mode.

PERSONALITY MODE

When in Service Mode, Personality Set-Up Mode can be accessed by pressing and holding the “+” and ”Enter” buttons simultaneously for 5 seconds. A two-tone sound will
be heard, indicating the action was successful. A moment later, the control will display the Personality ID of the model (signified by PER). The Personality ID number can be
changed by selecting the “+” or “-” key (per Personality Table). Press the “Enter” key to Select the Personality and Exit Personality Set-up mode.

The contrd has calculated that the anode rod has been mostly consumerd or the time in operator has exceded the replacement timeline threshold.| Replace anode rod with GE approved Mode Depletion anode rod, for specific model application. Alarm can be silenced by pressing Mode “Hold to Reset’ button once. Depress and Hold reset button br 5 seconds after anode replacement (resets anode life to 100%).
F71| Current transformer rattled. F10 and F11 fault codes have at occurred during the sane heating cycle.| Check that black L1 Me passes trough the current sensor and that current sensor camecbr (J301) Is plugged in. If correct (and there is no damage to wIdng), the control cord needs to be replaced.
F72| Low fine voltage during operation. Sagging voltage occurs over time. not at power-up, like fault F76.| Check incoming line voltage within +10/-15% of either 208 or 240 VAC, depending upon power supply. The detected voltage can be viewed in “Monitor Mode”. Check heating elements are not shorted to ground.
F76| The voltage is too low at power-up. The control monitors tie input line voltage, and if the voltage is below 155V, the fail code wi be displayed.| Check electrical supply line connections. Voltage should measure within •10/-15% of either 208 or 240 VAC, depending upon power supply, The detected Voltage reading can be viewed in “Monitor Mode”. Check heating elements we not shorted to ground.
F-77| Stuck Key fault. This indicates there is a button on the front panel that is stock down (longer than 30 seconds). This button is inoperable. Other buttons work namely. If the buton becomes free, the fault code MI clear by itself.| Check to see if al buttons are operable. Ensure contrd board is properly seated and mounting seems are not overtightened (loosen screws and hand tighten kghtty). Replace control board, if issue persists.
F78| Water Leak Detected (when using leak detection accessory module).| Confirm presencebrigin of water le and repair, as required.
F90| E2 personality module is urplugged. Unit wi continue to operate using previously stored personality on Control Board.| Confirm model number/personally is correct. Reinsert E2 pram module (J808) into contrd board or replace if damaged. Personality can be entered in “Personalty Mode”, if PCB Information is not correct.
F91| New E2 plug detected (0 personality value).| Cycle Power. E2 module wi be programmed with stored information from control board.
F92| Personality Mismatch (PCB flash inbrmation and E2 module are not the same).| No service action required. Contra wit update based on E2 module information.
F93| No personality identified (Control Board and E2 module likely replaced and neither have an assigned Personality).| Assign correct Personality within Personality Mode (see Personality Table for correct ID).
F94| WiFi Daughter Board Failure| Confirm WiFi is available and attempt to re- establish comection through APP (see GEAppliancce.com/comect). Check terminal connection J602 to WiFi board. Replace WiFi board if no other issue found and connect to Wfl per At* instructions.
