Modern washing machines show an error code when a fault occurs. These codes indicate which system has a problem — water intake, draining, door lock, heater or motor. Brands use different codes, but the main groups are similar.
A fill error (E18 on Bosch/Siemens, 4E on many models, E11 on generic systems) is often a closed tap, low pressure or a clogged inlet filter. A drain error (OE on LG, 5E on Samsung, E21 generic) points to a blocked drain filter, pump or hose. These can often be cleared with simple checks; if they repeat, the valve or pump may be at fault.
A door error (DE/DC on Samsung, E40 generic) appears when the door won't close. A heater/temperature sensor error (HE on Samsung, E05 generic) and motor errors (E22, "tE") point to more technical causes that are not recommended for DIY.
Bosch, Siemens, LG, Samsung, Beko, Indesit and Whirlpool use different symbols for the same issue. Always match the code against your own brand's manual.
Do not repeatedly unplug to "reset", interfere with the heater/motor circuits, open the board, or replace parts from random videos.
A 166 Usta washing machine technician identifies which system the code belongs to, then tests it with measurements, so the real cause is solved, not just wiped.
The technician checks the code for the specific brand, then tests valve, pump, lock, sensor, heater and motor in sequence, because one code can have several causes.
Switch off and check the tap, inlet and drain filters, and that the door is closed. Simple water/drain codes may clear this way.
If the code returns immediately, it is a real fault; resetting only hides the symptom.
If the code repeats or relates to the heater, motor or door lock, contact a washing machine technician. See also our blog.
