Appliance Error Codes, Explained by a Technician
Your washer, dryer, dishwasher, fridge or oven is flashing a code. This is what it means, what you can safely try yourself, and the point where it is time to call. I am Ramez, owner of R3M Appliance Repair in Rockwall, TX, and these are the codes I see most in the field, checked against each manufacturer's own documentation.
Samsung error codes
4C / 4E
Samsung says 4C (4E on older models) means water is not entering the washer correctly.
5C / 5E, nD
Samsung says 5C (5E or nD on older models) means water is not draining from the washer at the correct speed, or not draining at all.
UE / Ub, UB, Ur
Samsung says UE (also shown as Ub or UB) means the load inside the tub is unbalanced.
dC / dE, dE1
Samsung says dC (dE or dE1 on some models) means the washer does not detect the door as closed and locked.
HE / hE, HC, hC, HC4
Samsung says the HE / hE / HC family of codes means the dryer is getting too hot, and almost always the reason is restricted airflow.
LC / LE
Samsung says LC (LE on some models) means the leak sensor in the base detected moisture where it should not be, even if you cannot see a leak.
LG error codes
OE
LG says OE means the washer could not drain the water from the wash cycle.
IE
LG says IE is a water inlet error: the tub did not fill to the right level within the expected time.
UE / uE
LG says capital UE means the washer stopped because the load is unbalanced and needs you to fix it.
LE / LE1
LG says LE means the motor is overloaded and locked, so the tub could not spin.
d80 / d90, d95
LG says d80, d90 and d95 (Flow Sense) mean airflow is restricted somewhere between the dryer and the outside.
AE / E1
LG says AE (E1 on some models) means a leak inside the dishwasher has tripped the float switch in the base.
Er FF / Er rF, Er IF, E FF, E rF
LG says Er FF is a freezer fan error, Er rF is a refrigerator fan error and Er IF is an ice maker fan error.
Whirlpool error codes
F21 / F02, F9 E1, F9E1
Whirlpool says F21 (F02 on some models) means draining is taking longer than expected.
F5 E2 / F5E2
Whirlpool and Maytag say F5 E2 means the door (or the lid on a top-loader) is not locking properly.
F20 / FH, F8 E1, F8E1, LF
Whirlpool says F20 (FH on some models) is a water supply problem.
