Hi Kelly, I have the LG...
Hi Kelly,
I have the LG dishwasher making the high pitched noise. I've now replaced the water inlet valve and entire motor assembly and still the noise persists. Any ideas? As I sit here typing its whistling away. Its currently on a normal cycle with 53 minutes left, sounds like the arms are spraying water if that helps.

Missy,
I ran my dishwasher last night and just opened the door and noticed that the soap dispenser door apparently did not open as there is unused dishwashing detergent running down the inside of the door. Hope this symtom helps

Hi Melissa,
I'm really sorry you had a bad day. No worries, I hope you're better!
I ran through the codes and I hear the noise when I put a load on the drain pump. It sounds like the pump is trying to start then gets stuck, then spins a bit and get stuck, etc. Almost like if you were to spin a motor and then grab it with your hand and it binds.
So it's a bad drain pump?

It could be , however, today's drain pumps do not continuously drain, they pulse drain. That is to let some food particles sink in order to flush them out of the dishwasher. I could be that there is food causing the sound that is trapped in the pump or it could be you got one of the pump the shafts has separated from the pump. Do you want to remove it and check it for debris in the pump? Let me know it you need info to do that.

Yeah that's what my drain pump does, you can hear it switch on to drain before the washer switches cycles and that's when the noise happens. My wife informed me while I was gone she had a repair man work on the dishwasher as it wouldn't drain and she said he pulled something out of the drain pump, so maybe whatever got stuck in there messed up the pump? I know how to pull it so I'll pull it and check for debris and report back. Thanks!

Ok I will do all I can to assist you Thank you
