Service Autotest
End users can only see E1-E2-E3-E4. During service autotest, other failures can be seen.
1.
To activate service autotest mode in touch models, set program knob at position 3, push SW3 button. Keeping SW3 button pushed, turn
program knob to position 2.
2.
After 3 sec, door will be locked, and machine enters service autotest mode. Release SW3 button.
In T0 "SA" will be visualized on LCD. In rest of the models "SAU" will be visualized on LCD.
The test steps are as below ;
Step 1
:
Selector position 1 will be “washer heater on”
Before heating it should take water till first level frequency then start heating.
Heater will be on max. 8 minutes. After 8 minutes if the temp. Doesn't change more than 2ºC, it will release ntc failure. ( E05 ). Or if the ntc connection
is broken then it should give again E05 ntc failure. At the end of heating, "sau" visualization should make slow blink to indicate that the step is over.
*During this step if eps detects high water level, overflow algorithm is applied and e04 is released.
Note : if user changes the selector position, machine will do what is defined for the new selected position.
Step 2
:
Selector position 2 will be “pump on”
Temperature will be measured, if it is higher than 50°c, it should take 80sec. Cooling water , and then make "drain+ 5sec.) If pump error is detected
e03 will be released.
At the end of pump activation, "sau" visualization should make slow blink to indicate that the step is over.
Step 3
:
Selector position 3 will be "dryer heater 1 & fan on "
At the beginning of the step, dryer ntc should detect and record the temperature.
Dryer heator 1 and fan should be activated for 3 min. At the end of 3 min dryer ntc should again detect the temperature, if
Δt< 10°c, it will release e14 failure.
If Δt ≥ 10°c, "sau" visualization should make slow blink to indicate that the step is over.
Step 4
:
Selector position 4 will be "dryer heater 2 & fan on "
At the beginning of the step, dryer ntc should detect and record the temperature.
Dryer heator 2 and fan should be activated for 3 min. At the end of 3 min dryer ntc should again detect the temperature, if
Δt< 10°c, it will release e14 failure.
If Δt ≥ 10°c, "sau" visualization should make slow blink to indicate that the step is over.
