Comments : 

When entering in 
service test, door 

will be locked. 

Test is over 
Door will be 

unlocked, machine 

will go to END state. 

 
The test steps are as below ;

Step 1: 

 
Selector Program 1 (Cotton) will be “HEATER ON” 
 
Before heating it should take water till first level frequency then 
start heating. 
 
Heater will be on max. 8 minutes after this 8 minutes if the temp. 
doesn’t change more than 2°C then it will give 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. 
 
Note: If user changes the selector position, machine will do what 
is defined for the new selected position. 
 

Step 3: 

 
Selector position 3 (Colours) will be a 12 mins test program where all 
functions of the appliance will be checked. 
 
Machine will make exactly the same algorithm of Super Rapid 12'. 
So, time for selector position 3 is 12 minutes. 
  
At the end of test program “End” is visualized on LCD and door is 
unlocked.  

Step 2: 

 
Selector Program 2 (Cotton Prewash) will be “PUMP ON” 
 
Temperature will be measured, if it is higher than 50 °C, it should 
take 60 sec. cooling water, and then make “Drain + 5 sec.” 
 
At the end of pump activation, “SAU” visualization should make 
slow blink to indicate that the step is over.
