Error 31
Error 31 indicates that the feeder needs a calibration.
To run a calibration:
-
Make sure there is no kibble anywhere in the feeder
-
Unplug the feeder
-
Replug the feeder while holding down the check button
-
'Run' should be displayed on the screen
-
Use the plus or minus buttons to scroll through the options until you see 'CAL'
-
Press the check button and Err 31 should begin flashing on the screen
-
Press the check button again and calibration will start. This involves the feeder running the belt and then door several times.
-
The LCD will display several numbers (these are not relevant to us for this)
-
When complete the feeder should show the normal operating screen and be ready to go, just reload the food.
