Thanks for the response! I’ve taken off the front door and the control panel- I’ve don’t see what looks like a control board.

The front control panel doesn’t seem to have anything significant standing out to me as damage

I just replaced the soap dish and drain motor (Noisy bearings, tripping an "0E" code , not draining). New soap dish in door replaced carefully so as not to move any control boards or plugs. Started dishwasher and water started to spray and abruptly stopped. All internet and LG repair info pointed to water fill valve. Changed Valve, put in new stainless supply line, (looked old), lots of water flow to sink. Hooked up dishwasher and still will not fill with water. We hear the drain pump at start and circulation pump after. No Water. Can you please help on what and how to test next step.

Suspecting float an/or possible control board. but would like to test before replace.

Thank you,

Terry

• Removed and cleaned out entire drain hose. Nothing blocked. Even cleaned out the siphon break assembly (White u bend at top left side).
• Cleaned out drain pump. Tested resistance: ~3 ohms. And when it runs it has a good amount of water pressure when draining.
• I ran it in drain mode with vinegar and clean water in a closed loop (e.g, I put the drain hose to drain back into the bu) for ~30 minutes. All good. Flowed away like a water fountain.
• Here is the predicament. It will drain… and then stop. A forced drain cycle will hear the pump go, but it won’t drain water. If I then blow out the line with a compressor from the sink side and have it visibly bubble up on the inside of the dishwasher, it will then drain. But then f I then try to run any normal cycle, it goes for ~20 minutes and then the OE code. So blowing out the “clean” line seems to reset it for a while, but not for long.
• Are there other parts or sensors that could be blocked that kill the drain signal?

Solved it myself! The y connection to the sink drain got plugged AFTER I started clearing the main line. Problem intially fixed for dishwasher hose was subsequently transferred to the y connections. Solution… always check all paths before and after you clear the main drain hose.

Symptoms:

Control Panel goes blank and the unit stops, house breaker has not tripped.

When immediately pushing start button, there is no power, no display.

After about 5 mins, when pushing the start button there is a PF error code. The unit then starts in the last cycle selected before the “power failure”.

The unit will run anywhere from 2 to 10 mins then the problem is repeated.

Left the unit overnight with the breaker open before closing it, the unit ran ~15 min before failure. The run time diminishes as it’s repeatedly retested.

Of Note:

Unit was hard reset several times with the breaker switched off from 5 min. to overnight.

The house power fluctuated quickly off/on 4 or 5 times when the dishwater not in use. It has not functioned properly since this occurrence.

I confirmed that the heating element resistance is correct, then soldered a spade terminal onto the wire to verify that it works (it does). I'd now like to make a permanent fix.

The part that is corroded is a small connector with a ceramic base and two spade terminals. The part is easily removed, but isn't identified separately on the parts diagram. Rather it's part of the pump case assembly (Part #ABT72989202). On this dishwasher the heater element cannot be replaced separately from the ($200-$300) pump case assembly.

Since the heater element works, I'd like to replace the electrical connector.

The body of the connector as shown below is 17mm wide, and there should be a spade terminal coming off to the left and right from the main body.

On the back side, I found the following numbers that may or may not be part numbers. I've had no luck finding the part online.

155 131 003
23       16
260C

Any help identifying this part and a place where I can buy it would be appreciated. Thank you!

I am a perfectionist. While this does not affect anything but the led numbers and I have no other issues with my machine. I still want this fixed. Thank you kindly.

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

2. I made sure the water connections were ok.

I don’t understand electronics but i would like to try fixing it… please help

The model number is LDS4821ST

I can unplug my dishwasher, then plug it back in. It will run, and then when I open it to unload, the power starts fritzing out. Like it blinks over and over, and beeps over and over. Nothing we does stops it except unplugging it. Had a repair guy come out, he said power cords were loose and he tightened, issue didn’t resolve. I read in a forum maybe replace the power cords, so I did. Seemed resolved for like a week or two, now it is back. Found an old answer on here where they took it apart and they were taking apart the unit and the control panel and it turned out that was loose. Wondering if I should try the same.

LG Dishwasher lights “fritzing” when on, making erratic noises

Here is a short video that illustrates the sound; https://photos.app.goo.gl/DVhXxf6kzxrjCj...

To me, it seems like something is rubbing or a bearing is going out. Any tips would be appreciated.
