WOLF Induction Cooktop Troubleshooting Guide
DIAGNOSTIC MODE
Diagnostic mode allows the Service Technician to determine the cause of the failure. In diagnostic mode, only the last error code is displayed.
To initiate diagnostic mode, the unit must be in the “LOCK” mode. Then, press and hold the universal “OFF” keypad for 5 seconds. The cooktop controls will now enter into diagnostic mode.
In diagnostics mode, zone LED bars will illuminate and display the last error code logged.
NOTE: If no errors were recorded, no LED's will be illuminated. Unit will beep, and return to "OFF" mode.
NOTE: If the “OFF” keypad is not released after 7 seconds, the diagnostic mode will be cancelled and the unit will return to the "OFF" mode.
NOTE: If any other input signals are detected from the keypad, the unit will not enter diagnostic mode.
NOTE: When in diagnostic mode all heating units are off.
NOTE: The unit will exit diagnostic mode if no inputs are detected from the keypad in 20 seconds.
NOTE: If the “OFF” keypad is pressed again anywhere within the diagnostic program, the unit returns to the “LOCK” mode of operation.
NOTE: There will be no audible signals during the diagnostic mode.
INTERPRETING HEX DECIMAL CODE
The zone bar light uses the first four LED's from the right (LED 16), to left (LED 1), to display the HEX DECIMAL code used to determine the error code. Each LED has a corresponding numeric value that needs to be added together to determine the corresponding error code. (See Figure 5.1)
When the sum of the corresponding numeric value of the illuminated LED totals 10 - 13, then a letter is assigned in place of that sum. Example: 10 = A; 11 = B; 12 = C; 13 = D.
NOTE: The troubleshooting guide list the corresponding illuminated LED's. (See Figure 5.2)
NOTE: Error code may appear in either display or both simultaneously.
Figure 5.1. Example of Error Code F3.
Diagram showing LED bar lights with numeric values. The top diagram shows values 8, 4, 2, 1 from right to left, with labels MELT, OFF/ON, HIGH. The bottom diagram shows similar LED bars with values 8, 4, 2, 1 and labels MELT, OFF/ON, HIGH. Below the bottom diagram, it indicates "0 = LED OFF, 1 = LED ON", and an example calculation: "Example above indicates 0011. Add corresponding numbers together (2 + 1 = 3). 3 means F3 (Error 3)".
TROUBLESHOOTING GUIDE
| ERROR CODE | LED ON 13 | LED ON 14 | LED ON 15 | LED ON 16 | POSSIBLE CAUSE | CORRECTIVE ACTION |
|---|---|---|---|---|---|---|
| F1 | 0 | 0 | 0 | 1 | Shorted Temperature Sensor on front Cooking Zone | Check connection. Replace front element |
| F2 | 0 | 0 | 1 | 0 | Open Temperature Sensor on front Cooking Zone | Check connection. Replace front element |
| F3 | 0 | 0 | 1 | 1 | Shorted Temperature Sensor on rear Cooking Zone | Check connection. Replace rear element. |
| F4 | 0 | 1 | 0 | 0 | Open Temperature Sensor on rear Cooking Zone | Check connection. Replace rear element. |
| F5 | 0 | 1 | 0 | 1 | Shorted Temperature Sensor as check on transistors | Check connections. Replace generator. |
| F6 | 0 | 1 | 1 | 0 | Open Temperature Sensor as check on transistors | Check connections. Replace generator. |
| F7 | 0 | 1 | 1 | 1 | Temperature of electronics exceeded 158°F (70 ° C) during operation. | Check installation of unit. Check for proper ventilation. |
| F8 | 1 | 0 | 0 | 0 | If the Temperature Sensor's are interchanged during the assembly or after a service call. | Verify and correct Temperature Sensor connections. |
| F9 | 1 | 0 | 0 | 1 | Mains voltage Vrms < 180 V. | Check Line Voltage Replace Control Board |
| FA | 1 | 0 | 1 | 0 | Time out communication | Replace Generator Assy. |
| FB | 1 | 0 | 1 | 1 | Check sum error | Replace Generator Assy. |
| FC | 1 | 1 | 0 | 0 | Boost Led Error | Replace Control Board |
| FD | 1 | 1 | 1 | 0 | Lock Led Error | Replace Control Board |

NOTE: If the unit is not working and no error codes are recorded, the likely cause is the control board or Generator assembly. In this circumstance replace both control board and Generator assembly together.
