Juwel automatic feeder with a red flashing light

We had to buy a Juwel automatic feeder for our Juwel RIO tank. The feeder is very simple to setup and use. When I turned the feeder on for the first time, I got a the red LED indicating that the device was on as described in manual. But after some ten seconds the red LED started flashing. I was surprised to find out that there was no mentioning about a red flashing indicator in the instructions manual, so I searched for a while on Google and found this forum and thread.

It turns out that the red flashing indicator on the feeder means that the drum is in the wrong position for it to be able to spin. Let me just say that the drum was in this position when I took it out from the package.

If you have this red blinking indicator on the Juwel feeder, gently spin the drum manually some degrees towards you or so that the text “Juwel aquarium” is pointing towards you. Then you can try by pressing the ‘M’ button to manually spin the drum. And for example test the amount of food it will dispense.

This is absolutely something that Juwel should have included in the instructions, but I hope this blog post will help you with the issue.

  1. I had the very same problem – thank you very much for your help! I agree, this is a strange omission from the manual.

    Thanks again 🙂

    • I am nice that this post helped you out! I had to worry about this a while, so it’s nice to be able to help someone that had the same issue 🙂

      And hopefully Juwel is reading this as well. Shame on you.

  2. This helped me as well – thank you 🙂

  3. I think I just broke mine. I think I turned it too far. Help!!

  4. 😛 I had the same problem and did even change the batteries first. Did not help. When I followed this “turn” procedure it works just fine.

    Thanks 😆

  5. I had the same problem, it works fine now ! Thanks!

  6. Im having this problem right now,
    what do you mean by “drum”?
    I’d be happy if you could be more specific…
    Thanks a lot!

    Brilliant thanks so much

  8. Thank you! Was just about to leave on a ten day trip and at the last moment before leaving the door turned on the fishfeeder…. only to find it didn’t work!!… Tried changing the batteries, reading and re-reading the operating instructions, but nothing more than just a red flashing light. Your page here provided the solution though. Thanks!

    Thanks very much for your advice, problem sorted. Absolutely right that this problem should have been highlighted in the user manual.

  10. Help, this does not work for me! I’ve tried turning and putting in new batteries but nothing seems to work. :/

  11. i had to open the device and move the gears a little bit.
    it works now.
    thanks.

  12. I tried all the above suggestions:
    1) manually spun the drum gently to set position. Worked a couple of turns and back to red light flashing and misalignment of feeder chamber (drum).
    2) unscrewed the feeder and tweaked the axils a bit.
    3) everything looked to be in order on the inside. No corrosion, no short circuits, no ash (black) burn marks. Nothing. Everything was perfect.
    Except the problem continued.

    Then I check the batteries with my battery checker. They needed replacement.
    Checked the new batteries, then installed them. Pressed the ON button and voilà
    it works just fine again. Tested it like 10 times again to confirm. Still works great!

  13. I had the verry same problem Thanks for your post, it solved my problem!

  14. Awesome! Thank you, this fixed mine. 🙂
