Aquaclear Motor Freeze Up?

[blackteles]

After I shut down all power to my tank during my weekly water change last weekend, I did my normal cleaning routine and fired everything back up again. One of my AquaClear 70's wouldn't restart...first time any of AC's have done that. Rather than freak out I removed the motor assembly, pulled and cleaned the impeller, reinserted it and reattached the unit to the filter. After another restart it fired right back up and no issues noted. Just wondering if those of you with AC's have had this happen to you?

That kind of happens to me ALL THE TIME w/ my Emperor 400s. I have to take the impeller out and soak it in vinegar-it's a real drag

This is normal for mechanical parts. When it is running it is properly lubricated(in this case water and grim is the lubricant) but once you turn it off and the lubricant settle down or thicken due to no movement, the parts will get stuck. Take an old car w/o proper maintenance as the same example and you will get what I meant.

Hehe, that happens with my Penguins from time to time, also will make alot of noise if there is filter floss wrapped around it too

One of my aquaclears rarely starts when I plug it back in. I usually take something long, like a pencil, and give the impeller a nudge..then it runs no problem!
