on most Samsung models it's always button 3rd and 4th going from left to right
Rotate dial anti-clockwise till it gets to tse
pressing the temperature button will show this icon and the right-hand valve will start filling
pressing the temperature button again will show 20 and the left-hand valve will start filling
pressing the temperature button a third time will show this 30 and the valves will stop filling filling
one shows the pump is emptying the water out of the machine.
this symbol show the other pump running this is called a recirculation pump.
What the spin button does in test mode
By pressing the spin button you will see this symbol come on for 5 seconds and go off automatically
The spin button on the Samsung washing machine will test the heating circuit for 5 seconds by energizing the element and testing Ntc as well
The heater should be drawing about 9 amp at 240 volts. the heating element is a 2000 watt element and should have an ohms reading of 28.8 or thereabout depending on age.
the NTC sensor value will depend on which one was fitted.
you could use a multimeter at this point if you are having problems with the heater, to see if you have voltage coming from the printed circuit board to the element.
What the start button does in test mode
To do this test it's a good idea to have the Drum full of water to the bottom of the door seal as you will also be able to test the heater etc while this is in operation.
the motor will we'll agitate in One Direction then switch to the other direction simulating the normal wash cycle, you will also be able to check the water valves heating element and both pumps while this is in operation.
Postion 5 on the control dial SPn is for testing the motor on varied spin
this will test the motor on your Samsung washing machine through varied increases in spin speeds checking PCB outputs and also motor rpm
you will see maximum speed displayed and also as the motor increases rpm the display will show the spin speeds
the setting for this will vary from machine to machine.
Samsung Motor test mode, position 3 on the dial
