Water Valve Test; Restart Feature - Fisher & Paykel SMARTDRIVE Service Manual

421827

5.1.3 Water Valve Test

The water valves can be activated in diagnostic mode by pushing WASH TEMPERATURE UP
button to activate the Hot Valve and WASH TEMPERATURE DOWN button to activate the Cold
valve.
Pressing each button once will activate the valve. To de-activate the valve press the same button
again. This is also good to use when installing machines as it takes the shock out of the fittings
and seals and allows checking for leaks on the inlet hoses, at both machine and tap ends.
Caution: Do not leave the machine unattended when either or both valves are operating.

5.1.4 Restart Feature

If a fault occurs in the machine, the diagnostic system will detect it. However, instead of displaying
a fault code immediately, the machine will try to restart. If the fault was only of temporary nature,
the machine will restart and finish the cycle. If there is a continuous fault the machine will try to
restart a number of times.
This process could take up to 8 minutes depending on the type of fault. After this, if the machine
still cannot restart, the fault code is displayed and the machine will beep continuously. The number
of retries will depend on the fault that it has detected, however the maximum number or retries for
any one fault is 32 times.
The restart feature is defaulted to "ON" when a machine leaves the factory. For servicing we
strongly recommend that this feature be disabled.
To disable the restart feature follow the procedures below:
1. Enter diagnostic mode (Refer to Section 5.1.)
2. Press the WATER LEVEL DOWN button so that the low water level LED is not lit.
3. Press the POWER button to turn the display off (the 5 leftmost wash progress LEDs will be
flashing).
4. Press the POWER button to turn the machine on.
5. The machine can now be tested on any cycle.
To turn the restart feature on, either repeat the steps above or switch off the mains supply to the
machine.
The restart feature can be permanently programmed in to the machine's memory. When in
diagnostic mode press and hold the ADVANCE button down at the same time pressing the
WATER LEVEL DOWN button. A long beep will acknowledge the setting has been retained in
EEPROM. Press the POWER button to retain selection as with size setting. To remove from the
permanent memory, repeat the above procedure.
Note: This feature is designed as a service aid only and should be left on in the customer's
home. To return to normal operation, and to reset the restart feature to the factory setting,
switch the machine off at the wall or disconnect from the mains supply.
5.1.5 Recycle Feature
The recycle feature, when enabled, will cause the machine to continuously repeat the cycle that
has been selected. At the completion of the spin cycle the machine will power off briefly then
power back up again and will start the wash cycle programmed.
This feature is useful to help identify an intermittent problem, and would be best used if the
machine had been taken back to a workshop for service.
To turn the recycle feature on follow the procedures below:
1. Enter diagnostic mode (Refer to Section 5.1).
