Samsung dishwasher not draining DW60M5050BB

[Popescu Alexander]

Wince a week ago my dishwasher is not draining anymore. Does the whole washing program but the water is not flushing. It just beeps like the program finnished. Sometimes it gives an 4C error, sometimes just hums. 

 

I've dismantled the damn thing and checked the draining pump and it spins just fine. The same with the solenoid from the 3-way assembly. The only thing i didn't checked was the recirculation pump. And that because it has a big condenser on one side and was afraid of not blowing that up. 

 

If someone has any ideas...i want to avoid buying a new one.

Thanks.
