K2 makign wierd noises

My k2 after I cleaned it with vinegar for 24 hours and put it back together. It sounds like its about to take off in my tank, making a really loud vibration sound, no electric current in the tank. What should I do?

thx dev

 

Do you have a WM K2? How old is it, how long have you had it running?

 

Sorry, just read your sig.... I just did this the other day. Cleand my K3 and didn't notice the bearing on the motor end of the shaft. The metal shaft goes through it and it is inside the motor. I saw it in the jug I cleaned it in. Sounded horrible. Make sure that plastic bearing is in there.

 

+1 plastic bearing. Without this it will sound horrible.

 

ya checked that and everythign is in place and put back together. Uggg i have it turned off right now since its annyoign me, only been running maybe total of 6 months. Maybe ill tear it back down and double check everythign and see.

 

Ya, the plastic bearing inside, and that the metal shaft is stabbed in the front cover properly.
