Did you clean the filter ? Could be due to air-lock. Try turning off the filter, prime it (depress the round 'head' at the top of the filter cover a few times) and turn on the filter again.
Hi everyone.
I am having a prob with my 2026 external filter . Well, my 2026 has suddenly stopped funtioning. And, when left on, there is a grinding sound that comes from the impeller, with no water being pumped in or out of the tank. Matter is made worst since i cant find the manual for troubleshooting tips...![]()
COuld someone please tell me why this is happeneing and what I can do about it?
Thank you so much....

Your impeller might be broken or there is something stuck there, check it out.
Something about the water & the fishes that calms me down.
Hi guys, thanks for your replies.
Well, I cleaned the filter recently, about less than a month or so. I just tried what the both of you suggested. However, this does not seem to rectify the problem with my filter. Think it may need servicing for something? If so, where do I go and how much would it be, would anyone know?
The place to send for service is Qian Hu. The cost will depend on what is faulty. There is no service charge. You just pay for the replacement parts.
My experience with them is been very positive.![]()
Does it sound like 'clog clog clog...'? If so, it is air-lock. Prime the filter slowly but firmly by holding the priming device down, hold it there and release, all done without turning on the filter.
Priming the filter with all your strength and high frequency will cause the o-ring in the priming device to break and cause you more problem.
The possible reason for airlock can be your surface skimmer if it is attached to the filter inlet.
This filter is design to have, inside the tank, the outlet higher than the inlet. If you switch it the other way and use the rain-bar as a vertical outlet, chances are your lowest point of the outlet is lower than your inlet, then after cleaning out the filter you will face the problem of starting it.
If you have a submerged pump, fix it to the inlet inside the tank. And if this still does not drive the filter to work, then something is wrong. Can go to QianHu to have the problem diagnose.. the labor should be $10.
if u r not too sure abt priming,,, fill the filter almost completely, then close it... then push the prime button a few times...then put on...
if does not work, most likely ur impeller is broken.
hi, it would not be good to fill the filter with water. you will damage the o rings as the pressure is too high.Originally Posted by AquaObsession
Hi Tagore I don't think you are quite right, by filling the canister filter as much as possible, even if it overflows as it sealed, there is less need to "prime" to remove air from inside, just need to prime to ensure that air in the inlet pipe is removed to create the siphoning action. Pressure will not increase as a result.Originally Posted by tagore
hold on bro, with no disrespect. water is denser than air. when you prime the canister filter, you are not only pushing air but total mass inside the canister. I know because farm staff destroyed many canisters that way with O ring bursts. Speak to rainbow farm at serangoon north avenue 2, I think her name is May.Originally Posted by Rupert
Thanks, I hadn't thought of it that way.Originally Posted by tagore
If you are having trouble using the built in priming system, I'll advise getting the Eheim Installation Set 1. After installing this equipment, you will not need to use the priming function. It's great for other Eheim canister filter that do not have the priming function too!

no doubt that water is denser than air. air is compressible but water is not.Originally Posted by tagore
i don't see why priming a full canister filter will cause the o-ring to burst. there is no way you can get enough pressure to burst the o-ring.
anyway, if there is air in the canister, it is very difficult or almost impossible to prime a filter. the water level must reach the canister pump head for the priming action to begin suction of water.

Disclaimer: this is a discussion for canister users, nothing personal.

All substances, gases, solids, and liquids, including water, are compressible. Some
substances just require more pressure per change in volume to compress than others.

But their staff personally experienced it

I am trying to cut n paste a column from petco.com but is unable to:
go to google and type "DO NOT FILL CANISTER WITH WATER. http://www.petco.com/Shop/Product.as...100126#details
under directions.

anyway i am too junior here. will learn from bro tawauboy![]()
I think what tagore said make sense. I was at QH and saw this staff changing the primer o-ring. The customer said every time he washed out the filter he 'prime like mad'. After the change-out of o-ring, the staff brought the customer to try out the repaired cover. All the staff did was:
- Fit the cover onto an empty cannister.
- Gently depressed the primer all the way down and let go - 1 time only.
- then wait for the water to fully gushed into the cannister.
- Then start the filter, and that's it !
It you prime-like-mad, chances are a part of o-ring will be 'clipped' by a particular portion of the cover and will form an loop. This is the place where water will start to fill up the internal of the cover and water will flood out from the handle where the wire come from, cos that's the 'lowest point of exit'. Quite difficult to explain but if you totally dismantle the cover you will know what I mean.
The QH staff told me the same thing. He said we should always leave the canister empty (no water) after washing the filter. For those with separate in/out valve, just open the inlet valve and water will flow into the canister. Then open the outlet valve. Water will continue to flow in until all the air are expelled. For 202x series, just prime once as described by Nicky. It is so easy and I have done this with all my filters (221x, 202x and 223x) for the past few months.Originally Posted by Nicky
I was very surpised when he gave me the advice because everone here talk about filling the filter with aged water etc so as to not kill the BB ! Seems like most of us are doing it the wrong and difficult way !
knowledge and willingness to share information is more important than seniority. all of us are still learning so let's keep on learning.Originally Posted by tagore

It's hard getting into the enclosed area of the cabinet as I keep my hose pipe as short as possible and the filter will be near the rear wall of the cabinet. I use Eheim installation set 1 to fill the inlet pipe full of water. When that is done, I simply switch on the power and the filter will do everything else. All my planted tank has been using this Installation set 1. No need to bend over into the cabinet, closing and releasing the inlet or outlet valve and no backwash of debris from the inlet hose. Good too for canister filter that do not have the priming function.![]()
