Affected model series617 / 517 / 417 (EFME, EFMG)
Quick answer
EH3 — Electrolux dryer code EH3 indicates power-supply voltage too low.
Model compatibility: Electrolux reuses codes across series and model years, so EH3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Electrolux dryer code EH3 indicates power-supply voltage too low. Start with checks that can be done safely from outside the appliance, then stop if the code returns. Use the full model number before following any model-specific diagnostic procedure.
Signs
Symptoms you may notice

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.

When to call a technician
Schedule dryer repair if EH3 returns after the safe checks. A technician can test the model-specific circuits associated with power-supply voltage too low without guessing from the display alone.
Seeing this code on your Electrolux appliance?
Book a specialist visit for a clear estimate and approval before any repair.
It indicates power-supply voltage too low. 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.
