Electrolux Washer Error Code EF4

EF4 means the washer detected that water fill pressure is too low, with no signal coming from the flow meter even though the solenoid inlet valve is open. The machine is telling you it commanded a fill cycle but cannot confirm that water entered the drum. This is most commonly caused by a closed water supply tap or inadequate water pressure at the machine's inlet connection.

You should not run a wash cycle while the EF4 error is active. The machine has halted operation because it cannot confirm water is entering the drum, and running a cycle without adequate water could damage the drum, motor, or heating element. Resolve the water supply issue before resuming use.

Resetting the washer may temporarily clear the EF4 code from the display, but the error will return if the underlying cause has not been corrected. The control board will trigger EF4 again as soon as the machine attempts to fill and detects no flow meter signal. Fix the water supply issue first, then perform a reset or simply restart the cycle.

Start by confirming that both the hot and cold water supply taps behind the washer are fully open. Next, check the inlet hoses for kinks and inspect the mesh screens at the hose connections for sediment or debris. If the supply and hoses check out, verify that your household water pressure is sufficient. If the fault persists after addressing these points, the inlet solenoid valve or flow meter may need to be tested or replaced.

If the cause is simply a closed tap or a kinked hose, there is no repair cost involved. If the inlet hose screens need cleaning, that is also a no-cost fix. Replacing a faulty water inlet solenoid valve typically costs in the range of $40 to $120 for the part, with additional labor costs if a technician is needed. A defective flow meter replacement can range from $30 to $100 for the part depending on the model.
