Electrolux Dishwasher Error Code F2

The F2 error code on an Electrolux dishwasher indicates an overfill condition, meaning the machine has detected more water than it should contain during normal operation. This detection happens through two possible mechanisms: the pressure sensor, which monitors water level inside the tub, or the float switch, a physical safety device that rises with the water level and trips when it reaches a threshold. When either of these signals an overfill, the control board activates the drain pump and waits up to 60 seconds for the water level to drop. If the water is not successfully evacuated within that window, the programme is interrupted and the F2 code is displayed.

The root cause is typically not simply too much water entering, but rather a failure somewhere in the fill or drain system that allows the overfill condition to develop. A blocked drain hose or a clogged drain pump can prevent water from evacuating, causing the level to rise continuously. A faulty inlet valve that fails to close properly can allow water to keep entering even when the control board has stopped commanding it to open. A malfunctioning flow sensor may give incorrect readings, causing the board to permit excess fill cycles.

Diagnostic checks should follow the fill and drain circuit systematically. Start by inspecting the drain pump for blockages, checking the drain hoses for kinks or obstructions, and verifying the inlet valve closes fully when de-energized. The float switch and pressure sensor should be tested for correct operation, and all associated wiring and connectors should be checked for corrosion or damage. Any water leaking into the base tray can also trigger the float switch even when the tub water level is normal.
