Brushless Flexipower BLAC Wash Pump Motor
The Brushless Flexipower Wash Pump Motor is
very quiet and its speed can be varied by the
Control Module. There are 2 connectors fitted to
the Brushless Circulating Wash Pump, a 2 wire
power cable and a 3 wire Data lead.
Flexipower minimum pump pressure 20% less
than normal pump pressure.
Flexipower Maximum pump pressure 20%
higher than normal pump pressure.
The BLAC wash pump also acts as a virtual
sensor - see pages 11 - 13.
Alternating Wash Motor.
Alternating Wash Motor
The Alternating Wash motor directs the water to the upper spray arm first and then to the lower spray
arm, this process is repeated throughout the programme.
Note: If the Cycle time is less than 60 minutes the water is directed to both spray arms continuously,
to ensure a good wash performance.
Heater
The heater is encased in a metal housing with integral safety cut-out and fuse. It connects to the
Circulating Wash pump housing via a bayonet fitting. Refer to the Wash Pump Motor description.
Thermistor
Situated on the sump. A temperature rise in the water is converted to a changing resistance value.
A rise in temperature will give a lower resistance across the terminals of the thermistor; the control
module monitors this value and when it is the same as that as defined in the programme selected, the
module will advance the programme out of the heating stage.
Low Rinse Aid
A float is fitted into the rinse aid dispenser, when the level of the float is near the bottom of the
rinse aid reservoir the float will trigger a signal to the Control Module to turn on the Low Rinse Aid
Warning Lamp.
