Eheim 2217 problem

  • We are currently upgrading MFK. thanks! -neo
hmm...maybe the canister is too low from the top of your tank and creating more pressure than usual? maybe you could elevate the canister so the pressure will be lessened. I have my canister by 4.5ft from the top of my tank to the top my the canister but it can still push water out of the spraybar quite efficiently..

maybe your motor got weak or something?
 
Can you post what media you are using & how it is stacked in the filter? How old is the filter? Are you using the Eheim tubing on the input & output? Have you cleaned the tubing? Are there any other devices in-line?

Tcarswell has gone over the most common issues that cause problems so I too am at a bit of a loss as to the issue. Keep up posted on what you find wrong.

Sure sounds like an impeller problem...turns fine under "no load" but slows??stops?? as load increases.
If it was me, I would strip the whole head..deep cleaning of the head/impeller..make sure impeller is not loose on the shaft and housing/cavity has no debris. I mean "Q" tip, tooth pick kind of cleaning.
After sitting dry for any period of time, you could have a hunk of dried goo in there.
All I can think of. HTH
did full cleaning last night with no luck. at no point was it sitting for a period of time. I turned it off and moved it from one tank to another and wouldn't start back up.

I tried that today, I put the canister on an old end table so the canister was just below the bottom of the tank, top was in the middle of the tank. still couldn't get it to pump the water through unless I lowered the outlet hose by a foot or two.

bottom basket then Coarse filter pad on the bottom (replaced last night), and then a bunch of bio media (rinsed in tank water last night) top basket. Yes I'm using the Eheim tubing on the input and output. I cleaned the tubing last night, no other device is inline.
 
this is not going to be directly helpful, but I will tell you that the same thing happened to me a few years ago with an Eheim, even to the point where it wouldn't work on the tank, but it would work when I held the spray-bar at floor level and sprayed it into a bucket . . . same thing you're going thru

all I can say is that I worked it out, but I don't recall how . . . I do know that I did not have to replace anything, change anything or do anything different. I just kept trying and eventually it worked (?!?!?!?)

Doooh..Sorry, had another post in mind...
Will still stick with impeller as the problem.
If you have the out put line below a certain point you end up with no more than an expensive siphon, with a little boost from an impeller that would slow/stop as back pressure increased..
 
Here is a pic of the impeller, shaft & one of the rubber bushings. Does your impeller have 5 blades & are they all the same length? If the impeller blades spin freely on the magnet, you will need to replace the impeller. Also, make sure there is 1 rubber bushing in the bottom of the impeller well AND one in the pump latch as these center the shaft properly.

Ok I've replaced the Gasket that goes around the head of the canister and the impeller shaft and bushings on it and it still doesn't flow water. I'm not seeing anything physically wrong with the impeller so I've attached some pics to see what people think. I'm a little reluctant to throw more money into this if it's not the impeller that could be bad. any thoughts or suggestions?
