Electrolux Dryer Error Code E63: Heating Element Ground Short (How to Diagnose Safely)

Updated: February 2026

Electrolux dryer error code E63 is commonly associated with a ground short at the heating element. In an electric dryer, the heating element should be electrically isolated from the metal heater housing and cabinet. If the coil touches the housing or insulation breaks down, current can leak to ground, causing unsafe behavior, breaker trips, or repeated errors.

Because a ground fault can be a safety issue, treat E63 seriously. If your breaker trips, you smell burning, or you see scorched wiring, stop using the dryer until the fault is corrected.

Symptoms that can point to a grounded heater

Breaker trips when heat is commanded.
Dryer heats erratically or shuts down quickly.
Burning smell or signs of arcing near heater terminals.
E63 appears during or shortly after a heated cycle starts.

Safety steps

Disconnect power before opening panels or touching wiring.
Allow the dryer to cool before accessing the heater housing.
If you are not comfortable using a multimeter, call a technician. Ground faults can be dangerous to troubleshoot incorrectly.

Step 1: Correct airflow issues that may have stressed the heater

While restricted airflow does not directly create a ground fault, overheating can damage heater supports and cause coils to sag or deform. That makes contact with the housing more likely. Do these airflow checks:

Clean the lint screen and wash off any residue film.
Inspect the vent hose for crushing and lint buildup.
Confirm strong airflow at the exterior vent.
Remove internal lint accumulations if your dryer has accessible ducting or service panels.

Step 2: Visually inspect the heating element area

Access the heater housing (often from the rear). Look for:

A coil that appears broken or sagging.
A coil touching the metal housing.
Burn marks or discoloration on insulators and supports.
Heater terminals with scorched connectors or melted insulation.

Visual clues can quickly confirm the direction of diagnosis, but always follow up with electrical testing to be sure.

Step 3: Test for a ground fault with a multimeter

With the dryer unplugged and the heater wires removed from the element terminals:

Set the meter to resistance (ohms).
Measure between one heating element terminal and the heater housing (bare metal).
Repeat between the other terminal and the housing.

There should not be a continuity path from terminal to housing. If you measure continuity or low resistance, the element is likely grounded.

Step 4: Test the element for normal continuity

Also test resistance between the two element terminals. An element can be partially intact and still grounded. You need both tests: terminal to terminal (to confirm the element is not open) and terminal to housing (to confirm it is not grounded).

Step 5: Inspect wiring and connectors for heat damage

A grounded element can overheat wiring and damage terminals. Inspect:

Spade terminals at the heater and safety devices.
Harness insulation near the heater housing.
Any connector blocks for melting or darkening.

Replace damaged terminals. Do not reuse a terminal that has lost spring tension, because loose connections generate heat and can start a repeat failure cycle.

Likely repair path

If a ground fault is confirmed, the heating element is usually replaced (sometimes as part of a heater housing assembly, depending on design). When replacing the element, also correct airflow restrictions and remove lint buildup to keep heater temperatures in a safe range.

After repair: prove the fix

Run a short timed dry heat cycle and confirm the breaker does not trip.
Verify steady heat and normal airflow outside.
Run a normal load and confirm dry time is reasonable and no error returns.

How to prevent E63 from coming back

Keep venting clean and avoid long, crushed, or kinked duct runs.
Use proper vent materials and keep the run as straight as possible.
Clean lint regularly, including areas beyond the lint screen.

If E63 returns after installing a new element, stop and recheck for harness chafing to the cabinet or a misrouted wire contacting hot metal. A technician can also verify the dryer is not running abnormally hot due to airflow or control issues.
