Model compatibility: Electrolux reuses codes across series and control generations, so EH4 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 EH4, the control is reporting line-wiring 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: line-wiring error. A symptom such as dryer may stop or restart can fit more than one cause, including incoming power outside the expected range or line wiring 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.
Turn the dryer off and disconnect power.
Check the breaker and whether other devices on the circuit show unusual power behavior.
Do not use an extension cord or power strip.
If the supply appears unstable or the code returns, have the electrical supply and dryer checked.
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.
Get help
When to call a technician
Schedule dryer repair if EH4 returns after the safe checks. A technician can test the model-specific circuits associated with line-wiring error without guessing from the display alone.
A returning EH4 should be diagnosed with the model-specific service path. Tell the technician whether dryer may stop or restart; that observation can help prioritize incoming power outside the expected range.

It indicates line-wiring 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.
