Reading the dishwasher display

A dishwasher reports its fault in the display window, or by blinking a cycle light a set number of times with a pause between groups. Count the blinks and pauses before opening the door. LG codes are short letter pairs; a capital O differs from a zero.

LG appliances show short alphabetic codes (OE, IE, UE on washers, Er plus letters on refrigerators) and, on ThinQ models, a Smart Diagnosis option. LG also builds many Kenmore Elite units. The codes apply to model numbers such as LDF7774ST, LDT5678SS and DLEX3900B; check the label on your unit to confirm yours.

What causes FE

How to fix it

  1. Load large pots and plates upside down so they do not trap water.
  2. Use only dishwasher detergent, not hand-washing liquid.
  3. Check the unit is level with a spirit level on the door and tub edge.
  4. Switch power off for a minute and run a short cycle.
  5. If FE persists on a level unit with proper detergent, replace the inlet valve or request service.

Questions

Is FE the same as AE?

They share causes. AE is a leak and FE is too much water, and some manuals list them together.

Does FE damage the dishwasher?

It is a protection, but repeated overfills can stress the pump.

Can I unplug a built-in dishwasher?

Use the switch or breaker that controls it if the plug is hidden.
