Help! I am having a problem with me VIP6 tissue processor. About every 4 to 6 weeks the processor has a error code that position 2 which is 80% has not pumped in fully in the allotted time. Sakura answers to this problem is either I need to use their formalin or the alcohol in the second station is too high a concentration. I have never had this problem before in any processor I have used. I still use the Shandon excelsiour tissue processor and use the same protocol in both machines with no problems in the Shandon. Sakura thinks it is a build-up of precipitating salts that is causing the problem but there was no sign of this when the service tech checked the rotary valve. After every process we not only flush with ETOH and xylene but also run a warm water flush from the first station which is formalin. I use a different bottle for the warm water but do use the same valve from the formalin bottle. When we have completed 7 runs we run the 3 warm water flush Sakura recommends. Even the service tech remarked that I was doing more than they recommend.
I am at a loss as to what it could be. My only conclusion is that maybe the valve in station 2 intermittently collapse or sticks for some reason. I wanted to see if anyone either is having the same problem or if someone has a thought of what the problem could be. I did purchase a refurbished machine. I would appreciate any thoughts, ideas, or even guesses that anyone has. Thanks in advance for any help.
