Daewoo Washer Error Code E9

E9 on a Daewoo washer means the MICOM, which is the main control board, is not receiving any output signal from the water level sensor. The water level sensor monitors how much water is in the drum and sends that information to the control board. When that signal is absent, the machine cannot operate safely and shuts down while displaying E9 along with a continuous beep.

No, you should not attempt to run the washer while E9 is active. The machine has halted operation specifically because it cannot monitor water levels, which means it would have no way to stop filling at the correct point. Running the machine in this state risks overfilling and potential water damage.

Repair costs depend on the root cause. If the fix is simply reseating a loose connector, there may be no parts cost at all, though a service call fee would still apply if a technician is involved. Replacing a water level sensor typically ranges from $20 to $80 for the part, plus labor. A MICOM control board replacement is the most expensive scenario, with parts and labor potentially totaling $150 to $350 or more depending on the model and service rates in your area.

Some causes of E9 are accessible to a knowledgeable DIYer. Checking and reseating the sensor connector is a straightforward first step that requires no special tools. If the connector looks fine, testing or replacing the water level sensor is also a manageable repair for someone comfortable working with appliance components. Control board replacement is generally better left to a technician.

A power reset may temporarily clear the display, but E9 will return as soon as the machine attempts to sense water level and finds no signal. The underlying cause, whether a loose connector, a damaged wire, or a failed sensor, must be corrected before the error will stay cleared and the washer will operate normally.
