FAILURE 5: SAFETY SWITCH ACTIVATED AT HIGH REVOLUTIONS
Failure 5 occurs when the safety switch is activated during high spin. This failure indicates that there probably is a mechanical defect.
DIAGNOSE:
1. Check the position of the safety switch.
2. Check the springs and the other mechanical parts that fix the
drum.
3. Check the wiring if there is a bad connection.
4. Check that the washer is installed correctly and stable.
FAILURE 6: DOOR LOCK CLOSING SWITCH FAILURE
While a wash cycle is running the internal door lock systems are scanned all the time. If during the wash cycle the washer computer detects
that the "DOOR SWITCH" is not closed, the washer will immediately stop all its functions. The door will stay locked.
DIAGNOSE:
1. Check for proper function of the "DOOR SWITCH" at the
inputs menu.
2. Check the continuity of the wiring.
3. Check for proper function of the "DOOR SWITCH."
The "DOOR SWITCH" is a normal open contact.
FAILURE 7: DOOR LOCK CLOSING FAILURE
While a wash cycle is running: the internal door lock systems are scanned all the time. If during the wash cycle the electronic washer
computer detects that the "DOOR LOCK SWITCH" is not closed, the washer will immediately stop all its functions. The door will stay locked.
DIAGNOSE:
1. Check the continuity of the wiring.
2. Check (in the programmer device) the correct function of door
locking and unlocking outputs and also of the input into the
switch for locking the door.
FAILURE 8: DOOR LOCK CLOSING FAILURE AT BEGINNING OF CYCLE
The washer will not start a new process when the door is not locked after pressing START.
Failure Message 8 will be generated each time the door lock sequence could not be finished once started.
DIAGNOSE:
1. Check door handle for damage traces and centering
against door lock.
2. Check if the input connector DL (door lock) is connected.
3. Check for proper function of the door lock closing switch.
4. Check the door lock wiring.
5. Check (in the programmer device) the correct function of door
locking and unlocking outputs and also of the input into the
switch for locking the door.
If the safety switch is not correctly mounted, install the safety
switch properly.
Replace any broken mechanical parts.
If there is a bad connection, repair the wiring.
Adjust the supports at the bottom of the washer.
If the input is not functional, replace the washer computer.
If the drain valve is defective, replace the drain valve. If the wiring
is not continuous, repair the wiring.
If the "DOOR SWITCH" is broken or malfunctions, replace
the door switch.
If the wiring is not continuous, repair the wiring.
Replace the switch or the programmer device, based on the
result of output/input inspection above.
If handle is damaged, replace handle. If not well-centered, center
door against door lock.
If the input connector DL (door lock) is not connected,
connect connector DL.
Replace the door lock closing switch if it is broken or does not
function correctly.
Repair the wiring if it is not continuous.
Replace the switch or the programmer device based
on the result of output/input inspection above.
