Whirlpool MAH3000 Cycle Sequence Definitions, Main Wash Target Temperatures, Water Valve Outputs

below the main wash target temperature. The heater monitors the water temperature through the thermistor in the heater assembly. Selecting the energy saver, will turn off the heater and will not affect tumble patterns.

Main Wash Target Temperatures

The heater will not be turned on if the following conditions exist:

1.Low level of the water pressure switch is not satisfied.

2.The door is open.

3.During the Bleach fill.

4.Energy Saver on.

DOOR LOCKED LIGHT OUTPUT The Door Locked Light Output signal powers a LED on the membrane pad switch of the LED washer. This output is energized when the washer door is locked.

VDC REFERENCE VOLTAGE OUTPUT The VDC Outputs are a reference voltage for many of the signal outputs. On the machine control, the VDC outputs are 24 VDC referenced from P2(3) to the individual outputs.

WATER VALVE OUTPUTS

The machine control determines whether the hot or cold Water Valve Outputs should be energized during the wash cycle based upon the user selections. When water fill is required, the machine control board will activate relays on the board, supplying power to the water valves.

The machine control gates the power to the hot and cold Water Valve Outputs. When the pressure switch senses that the full level is reached, the circuit opens and the machine control de-energizes the Water Valve Outputs.

The machine control will monitor the thermistor resistance and fill time to achieve proper wash temperatures.

During a warm wash the cold may be cycled off periodically to achieve the desired water temperature.

On a cold wash the hot valve may be cycled on and off.

CYCLE SEQUENCE DEFINITIONS

IDLE/PAUSE MODE (LED Model) After pressing the Off key, the entire washing machine will shut down after unlocking the door and will be in the Idle Mode. In the idle mode all the outputs are de-energized, all the LEDs and display are off.
