Electrolux Washer Error Code E34

E34 means the washer detected a disagreement between two water level sensors: the electronic pressure switch and the anti-boiling pressure switch 2. When these two sensors report conflicting water levels for more than 60 seconds, the control board stops the cycle and displays E34. The fault is most often caused by a blocked pressure switch hose or a problem with the air trap system.

A reset may clear the error temporarily, but if the underlying cause is not resolved, the code will return once the machine runs long enough to detect the incongruency again. A reset is useful for confirming whether a one-time glitch caused the fault, but it is not a fix for a blocked hose, waterlogged air trap, or failed pressure switch.

If the fix involves only clearing a blocked hose or air trap, the repair can often be done at no parts cost. If a pressure switch needs replacement, parts typically range from roughly 20 to 60 dollars depending on the specific switch, with additional labor costs if a technician is hired. Wiring harness repairs fall somewhere in between depending on the extent of the damage.

Start by emptying the machine completely, then locate and inspect the pressure switch hoses and the air trap for kinks, blockages, or cracks. Clear any debris or detergent buildup you find in the hoses or air trap. If the hoses and air trap are in good condition, the next step is to check the wiring connections at both pressure switches, and if those are secure, test the switches themselves for proper operation.

It is not recommended to continue running the washer while E34 is active. The error indicates that water level monitoring is unreliable, which could allow the drum to overfill or underfill without the machine detecting it correctly. Addressing the root cause before running another cycle is the safer approach.
