Electrolux Dryer Error Code E33

E33 indicates that the dryer's diagnostic check for the conductimetric sensor found an open circuit condition. The conductimetric sensor measures moisture levels in the drum to determine when clothes are dry. An open circuit means the electrical path through that sensor circuit is completely broken. The error is stored in the last alarm memory and corresponds to a failure in diagnostics position 8.

Running the dryer with an E33 error is not recommended for regular use. Without a working moisture sensor, the dryer cannot accurately judge when clothes are dry, which may lead to over-drying, energy waste, or premature cycle termination. There is no immediate fire hazard from the error itself, but clothes and dryer components can be affected by improper cycle operation over time.

Repair costs vary depending on the failed component. If the issue is a loose connector or minor wiring repair, the cost may be minimal, primarily covering a service call fee in the range of $75 to $150. Replacing the conductimetric sensor assembly typically adds $20 to $80 in parts. If the control board requires replacement, total repair costs including parts and labor can range from $200 to $400 or more.

In many cases, yes. Start by inspecting the wiring harness connected to the conductimetric sensor bars inside the drum for any obvious breaks or disconnected plugs. You can also test the sensor bars for continuity with a multimeter. If the wiring and sensor bars are intact, the repair may require replacing the sensor assembly or the control board, which is more advanced work.

A power reset may temporarily clear the error from the display, but E33 is stored in the last alarm memory and reflects an actual open circuit fault detected during diagnostics. If the underlying wiring or sensor problem is not repaired, the error will return the next time the diagnostic check runs. A permanent fix requires addressing the root cause of the open circuit.
