Just wondering if it is just me or is there an issue with K2's with high repair rates right out of the box? Is quality control really this bad? Or do I have a few lemons?

What kind of problems are you seeing?

when life gives you lemons...add vodka!

I received 17 K2 machines back in March.
Only had 2 with breakdowns. Dial valve 1 error.
Other than that, they have not given me any problems

Flow errors, leaks, optical sensor failures and defective rinse ports....all have less than 200 hours

Brand new k2's with less than 80 hours each and already have one heparin pump failure and one 12 volt failure!!!

Lemons,

I recieved 11 K2s in july, and on the first week water starts shooting out of the rinse ports on 2 K2s, one unit water leaking from the top of the air separator, and some alarm tests failing. 5 years ago I recieved 10 2008k units and did not have the problems i am experiencing with the k2 units now.

If you got a lemon out of the box, get it fixed now while it's still under warranty. I got 10 K2's in April, one of them kept pegging TMP. Venous pressure wouldn't calibrate. Didn't mess around, got a replacement level detector module, installed it and sent the bad module back.
