8.8. EXTERNAL COMMUNICATION PROBLEMS
The machine communicates with the PC (TraceTech SW) via the RS485 line. If the external communication
is not working, check the connection between the PC and machine. Check also if you have selected the right
machine communication address.
8.9. EXPLANATION ERROR MESSAGES
FAILURE 2: DRAIN FAILURE
Failure 2 occurs when the electronic timer detects that the water is not drained after 3 minutes in a Drain or
Spin Sequence. The failure message is displayed at the end of the cycle.
DIAGNOSE:
1. Check the drain tube of the washing machine If the drain tube is blocked: repair the drain tube
2. Check the drain valve If the drain valve is defective: replace the drain
valve
3.Check the wiring:
When the drain valve is switched Off, the drain
valve should be open. (normal open)
If the wiring is damaged: repair the wiring
FAILURE 3 : OUT OF BALANCE
Failure 3 occurs when the out of balance sensor is activated before the spin sequence has started.
DIAGNOSE:
1. Check if the out of balance switch is broken.
(Make sure shipping braces are removed)
If the out of balance switch is broken: replace the out
of balance switch.
2. Check the position of the out of balance
switch.
If the out of balance switch is not correctly mounted:
install the out of balance switch properly.
3. Check the wiring, the contact of the out of
balance switch is normally closed.
Check connector pins for loose connections.
If there is no continuity: repair the wiring.
FAILURE 4 : OUT OF BALANCE NORMAL SPIN
Out of balance at normal Spin will occur when a washing machine is badly loaded.
The machine will try up to 5 times to redistribute the laundry in the drum before the spin step is skipped.
This function will protect the machine against overload and assures the normal lifetime of the washing machine.
DIAGNOSE:
1. Check the position of the out of balance switch. If the out of balance switch is not correctly mounted,
install the out of balance switch properly.
2. If this failure occurs often. Use a fully loaded drum. A completely filled drum produces
less unbalance than a drum that is only filled for 1/3.
3. Check the wiring if there is no bad
connection.
The out of balance sensor is a NC contact.
If there is a bad connection: repair the wiring.
