Daewoo Refrigerator Error Code EF

The EF code on a Daewoo refrigerator indicates a flow sensor error. It means the control board detected fewer than 10 pulse signals per second from the water flow sensor during a water supply cycle. This tells the refrigerator that water is not flowing at an adequate rate, which can affect the dispenser and ice maker. The fault is triggered any time the measured flow falls below the minimum threshold the system expects.

The EF error is not a safety hazard. It indicates a water flow detection problem rather than an electrical or temperature-related fault. Your food will remain safely refrigerated while this error is present. However, the dispenser and ice maker will likely not function correctly until the underlying flow issue is resolved.

Repair costs depend on the cause. If the fix is simply opening a shutoff valve or straightening a kinked supply line, there is no parts cost. Replacing a clogged inlet valve screen or thawing a frozen tube involves minimal expense. If the flow sensor or water inlet valve assembly needs replacement, parts typically range from $20 to $80, with professional labor adding $75 to $150 or more depending on your location and the technician.

Start by checking that the water supply shutoff valve is fully open and the supply line is not kinked or pinched. Next, inspect the inlet valve screen for sediment or mineral buildup that could restrict flow. If the supply line and valve are clear and water pressure is adequate, the flow sensor itself may need to be tested and replaced. A frozen internal water tube is another possibility and can be resolved by allowing the refrigerator to thaw the line.

A power reset may temporarily clear the error code from the display, but if the underlying cause has not been corrected the EF code will return the next time the refrigerator attempts to supply water. A reset alone is not a fix. The water supply line, inlet valve, and flow sensor must be inspected and the root cause corrected to permanently clear the fault.
