Troubleshooting:
Call Parker Technical Support if assistance is required. 805-604-3400 or 608-338-7645
When this occurs:
Check the following:
Possible Solution:
When “Check Pump
Head” error occurs
with your piston head.
1. When was the last time you
had the head serviced?
1. If you believe the head is stuck due
to being dried out, you can try wetting it
by placing alcohol in the upper tubing
overnight.
2. Are you pumping a gritty
solution, or one that can
crystallize if allowed to dry out?
2. If it still won’t turn, contact Parker to
arrange an RGA to send your pump in
for service.
Help! It occurred in
the middle of the day,
and can’t afford to
stop dispensing.
1. Press the “A” button twice to
clear the error and return to
regular screen.
1. Send alternating Prime and Empty or
Flush commands, repeating the “A”
button presses each time the error
occurs. This “rocks” the head back and
forth and may get it running again.
If this gets the unit running again,
immediately run cleaning solution
through the head for a minimum of two
minutes before dispensing again.
2. If unable to do #1 above,
Call Parker Tech Support to get
assistance using Volume Mode to
try to loosen the pump.
When your piston
pump head seems to
turn and the motor
runs, but no fluid
flows.
Either the piston is broken, or the
coupler is loose.
Contact Parker for tech support or
to arrange for service for your pump
and RGA#
