Stand By Mode; Out Of Balance Detection - 'Bump Detect - Fisher & Paykel Ecosmart GWL15-US-96200 Service Manual

517792A
2.1.2 Display Module
The Display Module provides the link between
the washing machine electronics and the user.
Input on wash type, water level, spin speed,
start/stop and wash cycle time is given by the
user via the display push buttons.
Feedback on selection is given to the user by
Light Emitting Diodes (LEDs). Sound effects
accompany button presses.
2.2

Stand By Mode

If a Phase 7 machine has not received any instructions for 10 minutes after being switched on at
the power point, or after completing the cycle, it will automatically go into a low power "Stand By"
mode. The control panel will be blank as if it was powered off at the wall.
Before entering the Diagnostic or Option Adjustment modes, the machine must be taken out of the
Stand By mode. To do this, the POWER button will have to be pressed, or the machine turned off
and back on at the power point.
2.3 Out of Balance Detection – 'Bump Detect'
Past electronic machines have used a lever connected to a mechanical switch to detect if the load
in the inner basket is out of balance. On Phase 7 machines this system has been replaced with
electronic sensing known as 'Bump Detect'. 'Bump Detect' is software written into the Motor
Control Module, which looks at specific feedback from the Rotor Position Sensor.
No fault codes are associated with 'Bump Detect', and there are no hard and fast tests that can be
carried out.
If a machine continually goes into an out of balance condition then the following needs to be
checked in the order given.
1. Even distribution of the clothes load.
2. Ensure that the machine is both level and stable on the floor.
3. Check the weight of the inner basket (23.10 +/- 9.7oz / 10.480kg +/- 275g).
4. Check the RPS using a RPS Tester.
Note: If the OOB problem persists after checking the above, we would then recommend
replacing both the suspension rods and the rotor. It is highly unlikely that the Motor
Control Module will be the cause.
