There is another possibility.  If you use formalin in the first station, you 
should rinse out the first 2 containers when changing the processor and fill 
them with warm water.  You can then perform a warm water flush.  This is setting 
up a program with 1 minute in each of the first 2 stations, causing the warm 
water to be pumped in and pumped out.  Residual formaldehyde can crystallize on 
the rotary valve and cause the issue you are now experiencing.  A service tech 
can remove the rotary valve, clean it and grease it, and get you back 
functioning.  This would be a part of what your preventative maintenance should 
be doing.

Good luck!

Hey Sarah
The error code is a rotary valve error. "Rotary valve does not stop at the
required station after 2 times". My guess is that you have a bad rotary
valve sensor board. It could also be the sensor disk.
