What to do if the Marineland Penguin Bio-Wheel Power Filter stops working

When using the Marineland Penguin Bio-Wheel Power Filter, you may notice that the fish tank equipment is not working normally, or it may not work at all. To see how you can potentially get your hang-on-back filter to work, you can take a look at this troubleshooting guide from Aquarium Blueprints.

This article will be covering the following versions of this product:

  • Marineland Penguin 100 Bio-Wheel Power Filter
  • Marineland Penguin 150 Bio-Wheel Power Filter
  • Marineland Penguin 200 Bio-Wheel Power Filter
  • Marineland Penguin 350 Bio-Wheel Power Filter

1. The first step we recommend taking is to unplug the power filter, wait for a few minutes, and then plug it back into the same outlet again.

2. If your filter still doesn’t appear to be working normally, then you can try plugging it into a different power outlet as the one you have been using could be detective.

3. You should also make sure that you properly install your Marineland Penguin. Otherwise, improperly installed parts of the filter would most likely lead to issues that will stop it from working as intended.

Therefore, you should make sure that the following are installed correctly before you plug the filter in the power outlet:

  • Filter Cover
  • BIO-Wheel Cover
  • Impeller Housing
  • Impeller
  • Intake Tube
  • Mid-Level Intake Strainer
  • Extension Tube
  • Strainer
  • BIO-Wheel
  • BIO-Wheel Bearings
  • Filter Box
  • Filter Cartridge

4. Keep in mind that the hang-on-back filter needs to be filled with water first before you plug it into the power outlet. Otherwise, it won’t work.

5. If your filter appears to be quite dirty, then it may not function normally. In this case, we recommend that you rinse off as much debris as possible from the aforementioned filter parts.

To do so, we suggest taking water out of your tank and then using it to rinse these components. By doing so, you should be able to keep a vast majority of the beneficial bacteria living on these surfaces alive.

6. A common failure point for the Marineland Penguin Bio-Wheel Power Filter is the BIO-Wheel as it may stop spinning. To see how you can get this part to spin again, you can check out this troubleshooter.

7. The impeller is also a failure point as it may get dirty and/or work out over time, which may lead to pumping issues. To fix this particular problem, you can clean the impeller or replace it with a new one.
