[Histonet] Precipitate in Processor

Hello Everyone,  

Has anyone ever seen a (salt?) precipitate in their alcohols following formalin?  While changing the processor this morning, I noticed a precipitate in the 80% alcohol and 95% alcohol (NOT in the 70% alcohol).  It is white and grainy.  The alcohols were otherwise unaffected.

We are using a 10% NBF containing:
Sodium Phosphate, monobasic
Sodium Phosphate, dibasic

And our alcohols are all reagent grade.

Any help would be very much appreciated!  Thank you in advance!
