Model compatibility: Electrolux reuses codes across series and control generations, so E42 may mean something different on another appliance or platform. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
When an Electrolux dryer shows E42, the control is reporting door-open sensing error. The code narrows the diagnostic path, but it does not by itself prove which part needs replacement. Use the full model number before following any model-specific diagnostic procedure.
This code belongs to a defined Electrolux control family: door-open sensing error. The same display can accompany dryer may refuse to start, so the next step is to rule out door not fully closed before moving deeper into door switch or latch issue.
This record is based on Electrolux technical/service documentation for the 617, 517, and 417 front-load dryer generation, including EFME and EFMG electric/gas variants. Confirm the full model number because another control platform may use the same display code differently.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Open and close the dryer door firmly, making sure no clothing is caught at the opening.
Check the visible latch and striker for lint, debris, or obvious damage.
Disconnect power for several minutes, then try one normal start.
Do not force the door or bypass the door switch.
Important safety warning. Stop immediately if you smell overheating, see electrical damage, the breaker repeatedly trips, or the drum is mechanically jammed. Otherwise, stop after one safe reset/check cycle if the code returns.

When to call a technician
Schedule dryer repair if E42 returns after the safe checks. A technician can test the model-specific circuits associated with door-open sensing error without guessing from the display alone.
A returning E42 should be diagnosed with the model-specific service path. Tell the technician whether dryer may refuse to start; that observation can help prioritize door not fully closed.

It indicates door-open sensing error. Check the model number because code meanings can vary by dryer platform.
A brief power reset is reasonable when there is no sign of overheating, wiring damage, or a tripped breaker. If the code returns, the underlying issue still needs diagnosis.
Do not continue if there is overheating, restricted airflow, electrical behavior, or abnormal drum movement. Correct any simple external issue and test only once.
