2.3
Foam Sensing Operation
2.3.1
Excess foam detected when heating during the main wash
During heating, the Level Switch monitors for an increase in
pressure. Should this occur, the heating is switched off – regardless
of the temperature reached. The Thermostop step is skipped and no
indication of the fault occurs.
2.3.2
Excess foam detected during rinsing
During water intake steps, the Level Switch monitors for higher than
expected increases in pressure. Should the pressure become
excessive; the Water Intake Solenoid Valve(s) are switched off for a
periods of time.
2.3.3
Excess foam detected during spin
During a spin, the Level Switch monitors for a higher than expected
pressure (based on the spin speed setting). Should a higher than
expected pressure be detected, the spin speed is reduced or
interrupted. An additional rinse cycle is then automatically added to
the program.
2.4 Imbalance Sensing
The Electronic monitors for in imbalance condition by:
Monitoring the pulses being sent from the Tachogenerator.
Monitoring changes in pressure from the Imbalance Sensor.
