As suggested by other users in January 2009 I have replaced ORIGINAL EXPENSIVE ZALMAN COOLAN with noname nonoriginal Alphacool AlphaCola coolant and suddenly ALL problems dissapeared and Ï have no problem since. It seams that ZM-G200 really sucks, it agglutinates and it is causing all the flow detector related problems.
replaced the pump with a Eheim(16€), and let hot tab water run through the entire system You'll need some power tape to get the tubes to stick to the tab The force of regular tab water gets any of the blue sludge out easy enough. The flow indicator itself got this treatment as well The were 2 magnets by the way. After this my reserator has been running smoooooth!
My current cooland is car radiator coolant 20%, 80% distilled water, steer clear Zalman's!
I had a simular problem but mine was jus slowing down and failing, got it checked and cording to the guy that i sent it to it is a bad flow control unit
These units have been known to have bad indicators. The internal pump is weak too. you need an external pump just to get started. yo uneed a backup as well.
you can use the reserator with it unplugged using and external pump. this allows the coolant to be flowed thru the reserator like normal but without the faulty indicator or weak pump. my external pump flows just as good in the opposite direction of the internal pump with them both running and it's just an average pump.
After 3/4 of a year the pump of my reserator 2 broke down as well (PC is on 24/7, might have sped things up).
I bought an Eheim 1046 and mounted it outside the reserator. Flow speed is the same but the head is much bigger. There are a more than a few reports of the reserator having a weak pump, but this is a great alternative.
No, my real problem was/is with the zalman´s coolant. IMHO it is the cause of all problems. When it agglutinates, flow control is affected. You can buy stronger pump to force the coolant flow even with the agglutinated pieces inside, but better solution is
1)use different coolant
or
2)replace the zalman coolant regularly
IMHO when you have added the pump, you have removed the coolant from the tubes. I think without any agglutinated pieces in the tubes or R2 standard pump is OK...
Inside the impeller, you see two circles. Inside one circle is a magnet, the other is just a counterweight for the magnet. They are held inside the blade by a thin layer of melted plastic. Behind the impeller is a sensor for the magnet. Over time, the plastic corrodes and the magnet can fall out. So even when it is spinning, the sensor will pick up nothing, timeout, and shut down the pump. The reset switch just resets the timeout. Your magnet is lost somewhere inside the reserator...

I have completely taken apart my Zalman,
replaced the pump with a Eheim(16€), and let hot tab water run through the entire system You'll need some power tape to get the tubes to stick to the tab The force of regular tab water gets any of the blue sludge out easy enough.

Sorry, my comment was not helpful.
After reading your blog I realised your problem was not with the pump but with the flow control.

I have seen the exact same behaviour on my Reserator! Do you know what causes this?

So, type "Jack4Smith" and "blog" in google search and it will lead U there...

My magnet is OK, because it is working now without any problems for several months... The cause is the coolant...
