What could have happened is that he didn't flush the loop properly before switching to another pastel.. It takes an awful lot of flushing to get every last bit of pastel out. Last time I did that I ran > 15 liters of distilled through the loop before the last remnants of the old pastel have been gone. Could have done the water faucet flush thing as this would have probably been faster and required less time but I didn't want to move my machine....
I know, you probably right, he changed to the new EK pastel after few flashes with distilled water. He went back to yellow Pastel and before that I gave him Blitz#2 that I still had and so far no problem.
Tbh. I just have big issue with EK, maybe they have changed their customer support or the way they deal with people, but from my personal experience that I encountered about 2 years ago I'm not talking about their flaking nickel plating and blaming people, Im talking about something similar with their blocks messed up thread, anyways, no point going to details but I will not get anything from them.......period, they don't have the courtesy of admitting that they could be wrongEdited by NewUser16 - 2/13/16 at 12:13pm
