Section 7: Solving Problems
7.1 Troubleshooting
The following table is to help identify and solve routine problems with the stainer. More difficult problems
may require technical service. Contact your ELITechGroup representative for assistance.
WARNING!
Due to the electrical shock hazard, do not open this instrument or attempt internal repairs. Refer
servicing to qualified service personnel. Contact your dealer or ELITechGroup Service.
Table 12: General Troubleshooting and Diagnosis
Problem
There is no power to the stainer when
the power switch is turned On.
Strange information shows on the display,
and/or erratic stainer operation.
A reagent line will not prime when power
is On and you press the prime button.
A reagent line will not prime, even with
the priming tool (Section 6.3).
Stainer bowl fills with reagent after use.
Stain is leaking onto the counter.
Check the facility outlet and the power cord connection.
Check the fuses. Refer to the Replacing Fuses procedure.
CAUTION:
Fuse failure may indicate a serious internal problem.
Switch the power OFF, wait 10 to 20 seconds, then switch
power ON again. If problem recurs, install a computer-type
surge suppressor to protect the instrument from power
line transients. If possible, connect the stainer to a power
circuit that is not shared by centrifuges, refrigerators,
air conditioners, or other motorized equipment.
If the above steps do not solve the problem, consult
the Aerospray Service Manual, or contact your
dealer or ELITechGroup for assistance.
Follow the procedures in Section 6.3 for priming reagent pumps.
Press the priming button and listen carefully for the
sound of the pump. If you can hear the pump, try the
priming tool again. If the problem is not solved or if you
cannot hear the pump there may be an internal problem.
Contact your dealer or ELITechGroup for assistance.
A small puddle of stain around the drain inlet or the bottom of
the bowl is normal. If the bowl is filling with a large quantity of
stain, check the external drain tube for blockage. Make sure
the drain tube is properly connected and running continuously
down toward the lab drain or vented waste container, with no
loops, rises, or obstructions. Make sure the end of the tube is
not submerged. This can prevent proper drainage. The internal
drain may need to be cleaned or replaced. See the Aerospray
Service Manual or contact your dealer or ELITechGroup Service.
Check all external reagent lines for visible
signs of cracks or loose fittings.
Make sure the drain outlet is not blocked.
Make sure the drain tube is securely attached to the drain
port and that the tubing is not cracked or deformed.
Reagent leaks may indicate an internal problem (see
Section 7.3). See the Aerospray Service Manual or contact
your dealer or ELITechGroup for further assistance.
