My unit is about 10 years old. I always press the power button, then the Power Scrub button to start a wash cycle. However, today, within a minute or 2 of starting a cycle, the error code FE is displayed; the cycle appears to halt (the lights on the display go out), but the audible sound of a motor running is still heard. Retrying three times produced the same result. The LG Customer Service line had me "flip the circuit breaker" to power cycle the unit, but the problem occurred when I tried it again. Any suggestions?
For model number LDS5040ST

Hello Charles, thank you for reaching out. An FE error on your dishwasher indicates that your unit has experienced a fill error. The dishwasher has detected that there is too much water in the unit, and the drain pump is automatically turned on. We recommend you replace the float switch, part number PS3522787, to fix the issue. We hope this sorts out your problem!

It gave OE error, which the manual says not to drain. The advice is to clean the filter, but this dishwasher does not have a filter.
For model number LDS5040ST
PartSelect logo
Hello Maria, thank you for getting in touch. According to our research, the mesh filter assembly in your model is located just under the lower spray arm. You may need to remove the lower spray arm to access the mesh filter assembly. If the issue persists after cleaning the filter, then you may need to check the drain hose. If it is not clogged, then you may need to replace the drain pump, part number PS16223509. Let us know if you have further questions!

Not a question but a comment. I had e-mailed in earlier that i was having trouble with the ne code coming on after the dishwasher had completed its cycle. It was recommended that the vario motor be replaced, which i did. The ne code was still appearing so it was pointed out through youtube tutorials that the position indicator switch might need replacing, which i did.The ne code was still appearing at the end of the cycle so i watched more youtube tutorials, and found that when replacing the vario motor, you need to remove the small plastic cam switch that slides over the stem on the back of the vario motor, which i had thrown away with the old motor. so after purchasing a new cam switch and putting back on the new motor, my dishwasher is running perfectly! i am very pleased that you could help me and have the exact replacement parts that i needed. you saved me a whole lot of money ! thank you, tony

Dishwasher door became heavy and would fall to the floor if you didn't hold it up.
Removed mounting screws from sides of disher. Removed broken piece of connector assy still attached to hinge. Attached new connector assy to hinge then looped it around pulley with spring attached to opposite end. Need both hands to pull spring up to side of tub and connect it. I would suggest replacing both connector assemblies while you have the dishwasher pulled out. Push dishwasher back in and mount with screws.

The hinge spring and/or connector assembly were not functioning, so the dishwasher door was extremely heavy.
Replacing the spring and connector assembly (the cord had frayed and broken) was easy and took only a matter of minutes to do. Wrestling the dishwasher in and out of its space under the counter was very difficult. Because my kitchen is compact, I had to move the refrigerator first, then disconnect the Romex cable and water lines from the dishwasher before I could pull it fully from under the counter. The side panels have screws in the front and the back, so the appliance had to be moved out until its back was exposed. But I got the job done and the door works just like a new one now!
