Yes, the relays are on the main board. If the wash heater ohm tests okay (should measure around 12 ohms) then the problem is mot likely the main board.

Also, these units sometimes have an issue with the wiring in the door. If the serial number on the unit starts with 712 or lower, then this could be the cause. Black, tarry residue on the wiring harness inside the door would indicate that the unit is having these problems. If that is your case, call LG customer service at 800-243-0000 and have them refer to service bulletin # IDSW20070060.

Kenmore UltraWash (665.1384) won't start but lights are on

this could be the door switch that is bad or loose. Check that first. Then you are looking at doing some troubleshooting. The first thing is to see if there is a technicians sheet attached to that machine under the kick panel. If there is then you have something to use for performing tests. One of the tests most likely is to unhook the control panel from the control board and power it on. If you hear the pump come on for about 5 seconds, the control panel is bad.

You have to make sure the hoses are in exactly how they were before you took the drawer out because the is a bracket that guides the hoses so the drawer closes properly. It sounds like either a piece of the hose guide broke or the hoses are reversed.

I'm not sure how mildew can grow in a dishwasher that is working well, but after cleaning it and putting things back together, it does now seem to be working. I thought that the water wasn't filling but I guess the heating element heats up before the water fills the dishwasher. So when I tried again and started the dishwasher from the beginning and waited, it did progress to filling water and going through the whole cycle.

The first step in a dishwasher's program cycle is activating the drain pump. If there are obstructing objects in the impeller it could make noise, also if the drain pump's bearings/motor is damaged. I don't know what you meant by taking out bottom part, maybe it was the drain pump you checked?

If you didn't this is normally an easily accessible component, when you have it out you can also check that the impeller rotates freely and that it feels and sounds ok in the bearings.

Maybe there is a possibility to attach a sound file here, it would help to diagnose the problem.

Dishwasher makes a loud grinding noise when running.

Start by pulling out the lower rack. Then pull the nut off the top of the lower spray arm. then remove all of the visible hex head screws. lift up on this section. this should expose another level of hex head screws, then they should be removed and this section should be lifted up. once you reach the chopper blade, remove the obstruction, and put back together.

Noise when running

UPDATE, I took the dishwasher apart (lower filter and strainer area, below lower spinner arm) and voila there it was, 2-3 pieces of plastic actually more like the broken corners off some reuseable containers and some unpopped popcorn seeds. Once I took these out and reassembled it was the test drive...everything was back to normal, no more forcing/ grinding sounds. Relatively simple tear down and reassembly if you have toric bits (5 star). Maybe I was lucky or maybe it's fixed, either way the noise is gone for me. If you do it you might want to do it after a wash/dry cycle and tear down when the plastic is still warm (plastic gets briddle with age, heat and detergent. Good Luck

Noisey pump

Take the drain pump apart and look for debris, or broken pump impeller. Remove the lower spray arm and filter assembly, check for debris in the sump and check the drain check vavle to make sure it is sealing properly. While in there make sure the food disposer blade are not clogges with debris.
