AEG Washer Error Code E33

E33 indicates an incongruence between the pressure switch level 1 signal and the dry run protection 1 signal that persists for more than 3 seconds. These are two separate inputs the control board uses to confirm water is present in the drum. When they disagree, the machine stops to protect the motor and heating elements from running dry. The fault most commonly points to a failed pressure switch or a problem in the pressure sensing circuit.

No, you should not continue running the washer while E33 is active. The error code triggers a halt specifically to prevent dry running of the pump and heating element, which can cause serious internal damage. Running the machine in this state risks burning out components and could turn a simple sensor repair into a much more costly fix.

A power reset may temporarily clear the error code from the display, but E33 will return if the underlying hardware fault is not corrected. Because the error only registers after the signal conflict persists for more than 3 seconds, any reset is only a surface-level fix. The pressure switch and associated components need to be inspected and repaired to prevent the code from reappearing.

Some causes, such as a kinked pressure hose or a clogged air trap, can be addressed without replacing parts if you are comfortable accessing the interior of the machine. However, the primary recommended fix is replacing the pressure switch, which requires identifying the correct replacement part and basic appliance repair skills. If you are not confident working inside the washer, a qualified technician should handle the repair to avoid further damage.

If the repair only requires clearing a blocked hose or air trap, the cost may be minimal, covering only a service call in the range of $75 to $150. If a pressure switch replacement is needed, parts typically range from $20 to $60, with total repair costs including labor generally falling between $100 and $220. A control board replacement, if required, would be significantly more expensive, often $200 to $400 or more depending on the model.
