PROBLEM
TEST
Try to start the test (see page 6-2). If the control unit does
not enter the test mode, check the connections on the con-
trol unit. If the connections are good, replace the control
unit.
If the test is effected, wait until the top "wash program"
LED switches off. If this does not happen, the control unit
has discovered a fault in one of the following three compo-
nents:
- Door Lock Switch
- Pressure Switch
- Thermistor
If the door lock switch does not close the contact:
- Check that the connections have been properly made.
- Use a tester to check the voltage between contacts
BP3 and BP1. If there is no voltage:
- Check for power at the input of the control unit. If there
is no power, check the connections.
The program
- If there is power at the control unit input, but there is
will not start
no current at the door lock switch, use a tester to
check the output voltage of the control unit to the door
lock switch. If there is no voltage, replace the control
unit.
- If there is power between contact BP3 and contact
BP1, replace the component.
If the door lock switch closes properly, check the pressure
switch.
Disconnect the pressure switch from the wiring, and retest.
If the test is okay, replace the component. If the problem
persists:
- Check that the connections have been properly made.
- Check that the pressure switch pipe and the compres-
sion chamber are not blocked.
- Disconnect the wiring from the thermistor, fit a new
thermistor that is known to be working, and retest. if
the thermistor is okay, replace the component (the test
is only valid if the washer is cold). If the thermistor is
working, replace the control unit.
Check that the water feed valve to the washer is open.
Place the control unit in test mode (see page 6-2). Perform
Test 2 (testing the solenoid valve). Perform the following
tests when the LEDs switch off:
Water does
- Use a tester to check the voltage at the ends of the
not enter
wires connecting the solenoid valve to the control unit.
the tub
- Use a tester to check the continuity between the two
contacts of the solenoid valve. If the circuit is open,
replace the component.
- If all the above tests are okay, replace the control unit.
