Stand By Mode; Out Of Balance Detection - 'Bump Detect - Fisher & Paykel SMARTDRIVE Service Manual

3.1.2 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
LCD liquid crystal displays or Light Emitting
Diodes (LEDs) depending on model. Sound
effects accompany button presses.

Stand By Mode

If the machine has not received any instructions 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. "Stand By" happens after
a period of 10 minutes for MW, GW & WA machines and 2 minutes for the IW.
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 mains supply point.
3.3 Out of Balance Detection – 'Bump Detect'
On this machine the Out of Balance detection, is undertaken with electronic sensing, known as
'Bump Detect'. 'Bump Detect' is software written into the Motor Control Module, which looks at
specific feedback from the Motor.
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 checking in
the order given.
1. Even distribution of the wash load.
2. Ensure that the corner cabs are clear of the floor & machine is sitting on its feet.
3. Ensure that the machine is both level and stable on the floor with feet inserts fitted.
4. Check the bias spring is fitted and attached.
5. Check the weight of the inner bowl. Bowl weights are as follows:
 Compact: 7.30kg +/- 225g
 Medium: 8.37kg +/- 225g
 Large:
10.48kg +/- 275g.
Note: If the OOB problem persists after checking the above, we would then recommend
replacing both the suspension rods and the rotor.
Control Module will be the cause.
