The test steps are as below ;
Step 1 :
Selector position 1 will be "HEATER ON"
Before heating it should take water till first level frequency then start
heating.
Heater will be on max. 8 minutes.If temperature doesn't increase 2°C
in 8 minutes,machine will give NTC failure. ( E05 ).
Or if the NTC connection is broken then it should give again E05 NTC
failure.
L2 and L4 should fast blink during E05 error.
At the end of heating, "SAU" visualization should make slow blink to
indicate that the step is over.
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.)
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 "RAPID 15' "
