Auto Filter Board Flash Codes:
The auto filter board has two status lights, one for filtering status and one for the oil level
probe status. Both can be found near the center of the auto filter board. If these LED's are
not lit, this would be an indication that no DC power is present.
•
Filter Status Light (Green, LED7 )
1. Also called the "heartbeat", this LED indicates the status of the
actuator relays.
2. If this LED is not illuminated then there is no DC power to the auto
filter board.
3. All fryers in the fryer bank should be flashing the same code.
4. Table 2 shows the different flash codes and their meaning.
•
Oil Level Probe Status Light (Red, LED22)
1. Indicates the status of the oil level probe.
2. This is a two digit code. The first digit is a slow flash. The second
digit is a quick flash. If the LED is only flashing 1 flash, the oil level
probe function is disabled.
3. The code may change at each auto filter board.
4. Table 3 shows the different flash codes and their meaning.
5. If a 2/5 flash code is displayed, follow the troubleshooting steps in
this document for checking the resistance of the oil level probe. An
issue exists with either the oil level probe or the auto filter board.
