I'm having an issue with my filter and I was hoping someone could help or knew how to fix it.
As the title implies, I have a Hagen Elite Mini Submersible filter. When I first set it up, it was running fine up until I unplugged it to do a water change. I plugged it back in once the water change was done and it ran fine for a while and then started to make the most horrible racket.
I opened it up to see what the problem was and to my naked eye, it seemed like it was the impeller. When I plugged in the power, the impeller was rotating but coming in and out of its chamber, probably hitting the flow control piece and creating a very loud noise.
Every time I would take out the impeller, put it back in and it would work normally for about 15 minutes before it would start up again. Finally, I swapped it out for the upper part of another Hagen Elite Submersible which then worked quietly until today: when I did another water change.
I did the same thing: unplugged the filter, removed water, filled water up again, plugged it back it.
This time the impeller isn't moving up and down while rotating, but it's making a lot of noise. I ran it without the impeller in and it was very quiet so it can't be the electrical bits in the top part (which the manual basically says not to open or touch ...).
Anyone ever have this issue? I really don't want to unplug it and not have a filter running as I don't have another one to use in its place at the moment. They have a helpline which I will call tomorrow as they only operate until 4pm.
Does anyone know how to fix it? I would be really grateful for any help.
