Electrolux Washer Error Code E22

The E22 error code on an Electrolux washer indicates a problem during the drying phase of a washer-dryer combo cycle. Specifically, it signals that the anti-boiling pressure switch is reading a FULL water level condition when the machine is attempting to fill the drying condenser or complete condenser-related functions during drying. The anti-boiling pressure switch is a safety component that monitors water levels to prevent the drum from overheating during drying. When this switch closes on FULL unexpectedly, the control board interprets it as either a water fill problem or a blockage preventing proper water circulation through the drying condenser.

The most common root cause is a clogged drying condenser, which is typically blocked by lint, debris, or scale buildup that restricts water flow. A kinked or obstructed drain hose can also cause water to back up and trigger the pressure switch prematurely. A faulty drain pump that cannot remove water fast enough, or a pressure switch that has failed and is sending an incorrect signal, will produce the same fault. Wiring faults between the pressure switch and the main circuit board, or between the heater and ground (indicating current leakage), are less common but must be ruled out during diagnosis.

Diagnosis should proceed in a logical order: inspect the drain hose for kinks and the pump filter for clogs first, as these are the simplest checks. Then inspect the drying condenser for blockages and verify that the drain pump runs and moves water freely. Pressure switch continuity and resistance should be tested next, followed by a wiring harness inspection. If all components test within specification, the main circuit board may be at fault. Current leakage between the heater element and ground is a safety concern that requires careful testing with a multimeter or insulation tester.
