This machine is equipped with a bulk detergent
reservoir that can hold approximately 75-ounces
of liquid detergent. When the Tank Low or Tank
Empty LED is illuminated, more detergent should
be added to the reservoir.
The bulk tank level sensor is located in the
control panel area, under the dosing pump (for
900/905 models only).
The Tank Low or Tank Empty alert is set when
the bulk tank detergent level has gone below the
bulk tank level sensor.
Bulk Tank Level Sensor Diagnosing
The bulk tank level sensor is supplied with 5 VDC
from J801 of the main board.
If the bulk tank display status indicates the tank is
low or empty but the tank is full, verify the output
voltage at the main board J801, from pins 1 to 3.
If no voltage is present, the main board will need
to be replaced. If the 5 VDC is present at J801
of the main board, the bulk tank level sensor will
need to be replaced.
