Does the machine stop full of water?
If you set it to spin or drain, does it empty the water?
Has it worked since it was moved?
yes it stops full of water
leave it for a long while, it does some turns, wait turns etc
eventually empties and stops with 3e error
after it stops, set it to spin, then empties and stops no spin
yes it did work until 2 days ago
The 3E indicates a fault in the motor circuit of the appliance.
Unplug the appliance and remove the rear panel.
Check the wiring to the motor plug, check the motor plug and check the motor itself.
In particular, check the carbon brushes in the motor.
If they are worn or broken, replace them.
If stuck, free them off.
Refit the motor, reassemble the appliance and try it again.
If it's still the same you are looking at having to change either the motor or control board, possibly both.
Check the wiring, see what you find.
Hope this helps
Let me know how it goes or if you need more help
Where in the world are you located?
Sorry, I don't have a list of repairers for Australia.
http://www.samsung.com.au/ has a support section and a service locater.

You would need to determine exactly what part is at fault.
Unfortunately there is no test to determine it.
Hope this is has been of some help
Good luck with it.
