TROUBLESHOOTING

Remote control does not light up - power
indicator does not come on:

Check fuse on circuit board inside dispenser —
replace if necessary.

Check voltage at power input terminals inside
dispenser — refer to wiring diagram.
Pumps do not trigger from signals:

Check signal voltage and duration.

Check for flush error — press RESET to clear.

Check pump run and delay time settings.

Pump may be counting down a "lockout" time (if used)
from a previous activation.

Pump may be trying to activate its "second level"
feature (this applies to pumps 1 - 6 only).

System may be set for Drain Mode, which requires
pumps to have a drain number assignment to
activate.
Pumps will not turn when trying to prime, or
during a washcycle:

Check for loose pump motor wires.

Check for voltage from circuit board to motor.

Check for mechanical binding of moving parts.

Flush errors keep occurring:

Check to see if a flush manifold is used — if so, is it
operating correctly?

Check flow switch for proper connection to dispenser
and proper water flow. Jumper JP1 should be set if a
flow switch is not used.

Press RESET to clear flush errors — pumps will not
run during flush error.
Pumps run but do not dispense product:

Check product containers.

Check squeeze tube for wear.

Check condition of roller and pump housing.

Check for air leaks on suction line.

Check for blockage from pump tube into flush
manifold (if used).
Pumps trigger more than once during cycle:

Check supply signal input for repeat signals from
washmachine.

Check signal lock-out function.

If drain mode is used, verify if a second level is
programmed.
All pumps run at the same time.

Check signals from washmachine.

May be using relay mode with drain mode enabled.
