Errors


Boiler type Enduro TI ETI-1000

Error code FLU

Cause:

FLU indicates excessive flue pressure. This code resets automatically after the high pressure condition is resolved. The second line indicates pump status.

Solution:

- Assure the flue is not blocked.
- Check the switch wiring by applying a jumper in place of the switch. If the code clears with the jumper in place, REPLACE the flue switch and connect the wires to the new switch BEFORE running boiler.
