    517794B ELECTRONICS Motor Control Module The Motor Control Module used on the AquaSmart™ washer is similar to the other Phase 7 washers in its physical size and shape, however the electronics have different software to control the unique aspects of this machine. Therefore the Motor Control Module is specific to this machine and is not interchangeable with any other Phase 7 machines.

    517794B Dispensing System Two hoses of different lengths run underneath the top deck and connect to either the detergent dispenser or the fabric softener. The detergent dispenser hose has cream elbows. The fabric softener hose has grey elbows. Moulded into the top deck at the valve end are identification letters (‘D’...

  • Page 15: Low Profile Agitator

    517794B An internal piston within the nozzle moves with the amount of water pressure against it. When the water pressure is high, more holes in the nozzle are exposed, and the backpressure on the dispensing valves is less. When the pressure is low, more backpressure is created, which ensures that either during detergent dispensing or fabric softener dispensing the dispensing system takes priority.

  • Page 16: Smart Pump

    517794B SMART PUMP™ SmartPump™ provides a more flexible and efficient pumping system than a conventional pump/diverter valve combination. SmartPump™ can be diverted quickly, it reacts faster and is better controlled. In addition, SmartPump™ has the capability of pumping to a much higher head whilst maintaining a constant volume flow rate regardless of pump efficiency degradations due to age.

  • Page 17: Rotor And Stator

    517794B 8.1.4 Rotor and Stator The rotor and stator magnetically interact with each other in order to convert electrical energy into rotational movement of the rotor Rotor The rotor assembly is a complete unit that is permanently fixed into the pump housing. The resulting cavity is charged with water, which acts as a lubricant.

  • Page 19: Slr Feature

    517794B SLR Feature Feature stands Simplified Leak Recirculation. This feature has been added so that should the flapper not completely seal against the housing of the pump when draining, water can bypass through this hole and back into the pump, avoiding recirculating back into the bowl and on to the clothes load.

  • Page 20: Testing Smartpump™ At The Stator

    517794B If the meter shows an incorrect reading, we would recommend testing the stator from underneath the machine, as there could be a fault in the wiring harness. To test the stator it will need to be removed from the machine (refer to Section 17.12). 8.4.2 Testing SmartPump™...

  • Page 22: Out Of Balance Detection - Bump Detect

    517794B The straps serve two purposes: 1. To limit radial bowl motion during agitate. 2. As the straps stabilise the bowl, it also improves wash performance. If one or more straps break, this can cause an increase in out of balance activity, which again may lead to cabinet damage and noise from loose straps.
