Centrifuge turns on, but gives error messages 20 & 21. Instruction manual says to contact technical service reps because of an electrical issue. Eppi reps quote for repair is my first born child.
1. Does anyone have the service (not instruction) manual to the 5415R centrifuge series?
2. Does anyone know what are Error 20 and Error 21?
3. Does anyone know how to fix error 20 and error 21?
Many thanks in advance!
