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 IE

How to fix it

  1. Check that the kitchen and bathroom taps have water.
  2. Look under the sink and straighten the inlet hose where it is bent or crushed by stored items.
  3. Open the shutoff valve at the dishwasher by turning it counterclockwise.
  4. Open the upstream shutoff valve fully as well.
  5. Restart the cycle.
  6. If the valves are open and water reaches the hose, replace the inlet valve.
