Product review (1 stars): Reliability Problems
We have had the same issues others have had.

In our case we do dishes around every other day or every day, and we use to use normal dry soap.  The dishes never seemed to get clean and the system broke while under warranty.  It was fixed and the repair guy told us that we were using too much soap.  So we reduced the amount of soap and the dishes came out worse.  We then had it break again this time out of warranty and it cost about $400 to get fixed.  We then switched to the gel packets and the cleaning was acceptable.  Granted they are expensive, but at least they worked and cleaned our dishes.  Now the system broke again.  It looks like the pump again, so we are going to cut our losses and get another dishwasher.  We are going back to Kitchen Aid.  We had that brand before our move to a new house and it lasted fine for over 10 years.

My advice is to avoid LG dishwashers at all cost.  We do have their washer and dryer though and they held up well so far (4 years).
