I've just rung Samsung as I had the error code 6e as well. Apparently its a water heater error!
Samsung suggested ringing the local service centre and getting an engineer out. From past experiecne its cheaper to find someone in yellow pages and get someone local out who dont charge a call-out fee!

I think is the water heater error... you can try to wash clothes with cold water. And buy some time then you have to go buy yourself new washing machine.
