Test Mode

4.1. Autotest
* This test is for quick checking of the product. You can not see the
failure codes.
1. Press SW5 button and simultaneously position program
knob to 1
2. After 3 sec, door will be locked and the auto test starts.
The test steps are as below;
Step1: The pump is activated for 3 seconds and there is EPS
check , the frequency value should be between the 46.04Hz and
43.40Hz. It checks the EPS and if it is OK it continues the autotest; if
it is NOK then it should give E10 ERROR & cancels the autotest (
goes to the selection mode ). Also if any frequency can not be
detected, then it means there is problem with connection or EPS, so
it gives E10 which is EPS error and cancels the autotest.
L1-L3 and L4 should fast blink during E10 error for panels except F4.
Step2: The motor ramps to max spin for 15 seconds. While its
speed rising up to the maximum speed the EV1 (prewash valve) is
activated for 5 seconds and then the EV2 (wash valve) is activated
for 5 seconds.
Step3: The motor reduces speed to stop (depends on the motor
stop time) for 5 seconds. While it is slowing down it activates EV1
and EV2 valve, concurrently.
Step4: The motor turns to right.
Step5: The motor turns to left for 5 seconds.
Test is stopped. In that period, the Pre Wash icon makes fast blink.
Step6: The option 1 button is pushed
The EV1 and EV2 are activated concurrently until it reaches
pressure sensor's first level frequency ( Hz ) for 5 seconds.
Step7: Software will detect NTC's resistance value and will check
if the temperature is between 5°C < Tdetected < 40°C . If it is inside
the range, heating step will be done. If temperature value is outside
the range, then it means NTC is detecting the temperature in a
wrong way and heating step will be skipped.
Step8: Autotest ends and "End" is visualized on LCD for F4. For
F2B, F2A,F2B and F2C ''End'' led will be fix on.
