My Koralia 4 just stopped working...

Yeah I am going to clean my other K3 while I am at it.

 

which reminds me , i need to get a cleaning on my Koralias. Vinegar/water wash seems to work well. Hope you have luck getting it to work again.

 

Sounds too simple, can't see what kind off crap has built up in there. I really hope this will do the trick.

 

I clean mine every other week. Dead algae on one of my K1 clogs the water flow and the coralline algae on my other K1 drives me nuts. I clean it off and it grows right back!

 

Yeah, this has happened to me before on my K3's.
Just a huge buildup of gunk on the metal shaft and magnet that cause so much friction that it can't continue to turn.

 

so after a quick bath in vineger an water and a good scrub my k4 is alive again, its like magic. thanks guys

 

Tada!!!!
