Brand new aF4: Not Feeding or no flow out of the gray tubing?Updated 5 months ago

This can be caused by the aF4 being out of service for a period of time (30+ days) and is especially common with brand new aF4s. The technical term for it is "stiction".

The solution is quite simple!
1. Empty any food that may be in the reservoir and replace the reservoir in the aF4.
2. Insert both the gray tube and black tube into water (at least 12oz).
3. Press and hold "Auto Clean" until you hear the solenoids clicking (about 10 seconds).

This process will solve the stiction problem nearly 100% of the time.

To test if you've beaten the stiction issue, lift the gray tube from the water and press "Feed Now" on the aF4. After a moment, water should be flowing from the gray tubing.

If you still have no flow, repeat steps 2 and 3.
