Why is my Dishwasher doing this weird sound?

My LG Dishwasher is doing a grinding noise since 2 months ago. It's showing me the E1 error.

1. I've cleaned the whole dishwasher and removed all the gunk.

2. I made sure the water connections were ok.

You can hear the noise on youtube at:

Thanks for your reply.

I've checked under the dishwasher and there's no leakage. Also, the drain hose is looped up above the sink drain. I've seen the link before.

My model is LG LDS4821WW


Hi, It could still be that the pump is faulty.
