Reading the washer display

On a washer the code appears on the digital display or as a pattern of flashing cycle lights. Note it exactly, including any dashes or sub-codes, then unplug the washer for five minutes and run a short drain cycle to see whether it returns. 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 tE

How to fix it

  1. Unplug the washer for 10 seconds to clear a temporary fault.
  2. If you added very hot water, let it cool before restarting.
  3. Open the cabinet and inspect the thermistor connector at the tub for corrosion or loose pins.
  4. Measure the thermistor resistance against the service data and replace it if out of range.
  5. Restart a cold-water cycle to confirm.
  6. Call for service if heater and sensor circuits check out but the error persists.

Questions

Does tE affect cold washes?

Some models still run cold cycles; others stop completely.

Is the thermistor part of the heater?

They are separate parts but sit close together in the tub.

Why does tE appear after a long hot cycle?

Heat can reveal a marginal thermistor connection.
