My LG dishwasher has started to make a loud/deep grinding type noise. It's not on the entire time during the cycle. I've attached the audio file. Any ideas? Would it be a piece of something that go through down into the motor or something? Why does the noise not occur all the time, perhaps when the pump comes on? Does a dishwasher start for 1/2 minute filling with water before the pump kicks in or something?

The bad noise starts at 00:39 seconds.

put the audio onto a youtube video so you don't have to download a file...

Sounds like the drain pump has something inside of it. 

The reason I say this is because it sounds like the main pump is still working while this other noise starts up and then slows down.  That's the only other pump in the sump assembly.

thanks - if it's something that got stuck in the drain pump is it something you could have a crack at fixing yourself (i.e. DIY).  That is getting to the pump and opening it up?

Found a video that shows how to get to it (not open it up)
