Common problems of Eheim Pro II 2028 Canister filter

[atlantis]

I have a the same problem. Brought it to LFS (C32 and was advised that I just need to glue it back. Seems like a common problem.

I just glued it back with plumber's glue and its running well again.

I have this problem too!

I also have noise producing from the filter after my last cleaning. From previous experience, the filter should be super silent during operation.

As for the white plastic, it is intact. So should not be the issue.

If the impeller is perfectly ok visually...No sign of wear or damage. How to know if we need to change it?
Maybe this impeller needs balancing over time?

Now, I am not sure should I replace the impeller. It is quite costly and what if it is not the impeller problem?

How about the ceramic shaft for the impeller, when do we really need to change it? For mine, there is no sign of wear or damage.

Anyway, what is the best way to test the impeller whether it is in perfect condition? Anyone could advise? Thanks.

Luckily, my 2028 is working fine and quite silent so far for past 4 months (cleaned twice and adjust the flow rate a few time with no problem)... sad to hear about the case with other bros.. guess I'm lucky!

For your filter, since it is only 4 mths old... it should work fine and silent.

In general, I think such parts are subjected to wear and tear and thus need to replace over time.

I seem to have a flow rate issue. No noises. Bought if from LFS about a month ago. The indicator for the flow rate is at halfway thus I reckon it means that instead of 1050l/h its probably only doing about 500l/h. I removed all the filter media and still have the same problem so nothing to do with the media. Its either the empeller or the coil .. I think. Will get in touch with Eheim soon to find out more. But does anyone here face the same problem?

[aquarius]

Hi Naquatics, please do update on what's the problem once eheim get back to you. Thanks.

[cheetf]

In my case, the impeller's white plastic separated from the magnet - about a year into use.

Same problem for my 2026 too.

Same problem for my 2026 too.

My atman's white colour part of the impeller also came off after a short period of usage. Didn't expect that eheim's impeller to be just as crappy based on the feedback here.

[Naquatics]

The flow rate is now down to 25%. I am getting a bit annoyed. Don't expect this from Eheim! Just *** luck I reckon. I'll bring it toYi Hu tomorrow. Cheeze!

[Naquatics]

This shows the flow rate at 25% although the lever is set to max.

I sent the unit to day to Yi Hu and was serviced by the guys. One of the guy was not friendly at all. I was made to wait some 45 mins before they got back to me. Anyway, end of it, they tested with a new set(just the top part) and the result was the same. Imagine, new out of the box and the flow rate gauge shows the same at between 25%-35%. So I have nothing to say but accept that they are all the same. But this bring another issue. Why bother having the gauge if it means nothing? Does it really show the actual flow rate? Or just for show? I am a bit annoyed as the bloody thing cost some $300 bucks and with this result. I wonder if they are done in a country with low QC. What has Eheim become? I wish this was in the US where we can just return if we are unhappy!

Eheim has yet to respond. So lets see what they say. If they do not respond soon, I would not look good on them. And their brand will be questionable especially when its over-priced for just plastics and magnets!

is the 2026 as problematic as well ?
I am getting one 2nd-hand from a seller at arofanatics....

I personally am using a 2217 and rena xp3, and are very satisfied with them , but seeing this thread makes me think twice about committing to the 2026...

any comments guys ?

I hope I am not screwing your transaction. The seller will probably kill me! Not sure about the 2026 but I think Eheim must address the issue of the flow rate indicator.

Any other users of 2026/2028 facing the same problems? Or am I just the one with the *** luck!

From your picture, seems like they change the "indicator". The ones I have was this white ball like thing, rather than the red object shown in your picture.

Let's see what's the reply from Eheim.

hmmm ok, the problem with the flow rate indicator.
but is the actual flow rate ok ? because i don't really care about the indicator anyway, the actual flow rate matters more

I guess if the flow rate is ok then its fine. I have yet to test the flow rate. I might do it when I have time. As for me, if I pay some 300 bucks for this filter, I would expect these small things to work. Otherwise don't have it in the firt place. I guess I am just particular.

[aquarius]

You are not being fussy/particular since you paid good money for a filter considered by many of us to be the No1 brand in cannister filter. If it's a china brand than it's a different story since you'll be paying for what you get and you're right that the flowrate indicator shouldn't mean nothing since it's there to help you know when to do your maintenance otherwise might as well go get the Pro 222x series which is cheaper.

Since like what valice has highlighted that the old indicator has a white ball in it than it'll be good that people who has the new and old type indicator comment on this. Maybe that batch which Yi Hu has is defective since the new ones which were tested also has the same problem.

[samuelgoh]

can i presume that the only problem with the 202Xs is that the indicator is faulty ? and that the flowrate itself is ok ?

samuelgoh, I am currently in correspondence with Deric Ong, EHEIM Asia Pacific Pte Ltd. I'll ask him on this issue and get back to you.

Incompetent product design, presume that the “ball type” flow indicator might end up as something as a flow obstacle, because it place after the pump’s propeller that the pump need some extra flowing force to pushing it (so shown the flow output), but will eventually slow down the entire flow turn-over rate. Further more this design will narrowed the actual water-flow-line (where minimize the gap that allow the water to pass thru).

Beside that the pump’s pressure head is considerably poor (0nly 2.0 meter high). No wonder the Eheim Pro 3e now use electronic type instead of physical ball type.

[Naquatics]

I called Deric from Eheim Asia Pac and he will be testing the Pro II 2028 for 2 weeks before letting me know. I guess its only fair to let him test it and see the result. I hope its a batch issue for otherwise Eheim's reputation may be tarnished. Anyway I am hoping for the best .... that a trusted brand does not fail us
