You might notice your laundry remaining cold during a hot cycle, a strange burning odor, or the machine suddenly pausing mid-wash. While “current leakage” sounds intimidating, it is a common diagnostic signal typically isolated to a single replaceable component. With the right tools and a methodical approach, you can resolve this and get your washer back to peak performance.

Symptoms of Error E68
The most obvious sign is the E68 code flashing on the digital display, often accompanied by an audible chime or the unit entering a forced drain mode. However, physical symptoms often precede the error code. You may find that the glass door feels cold during a “Sanitize” or “Heavy Duty” cycle, indicating the heater is failing to engage properly.

Furthermore, if your home is equipped with a GFCI (Ground Fault Circuit Interrupter) outlet, the washer may trip the circuit breaker immediately when the heating portion of the cycle begins. In some instances, you might hear a faint buzzing or see the lights on the control panel flicker as the board struggles with the irregular voltage return. Finally, the washer may simply “hang” at a certain time remaining, unable to progress because the water temperature hasn’t reached the required threshold.
Detailed Diagnosis: Root Causes
Understanding the “why” behind E68 is crucial for a permanent fix. Here are the primary culprits analyzed in depth:
- Heating Element Insulation Breakdown: This is the cause in over 80% of E68 cases. The heating element is a metal tube containing a resistive coil surrounded by magnesium oxide insulation. Over years of exposure to hard water and thermal expansion, the outer metal sheath can develop microscopic “pinhole” cracks. Water enters these cracks, creates a bridge between the live coil and the grounded outer shell, and causes the current leakage.
- Wiring Harness Abrasion: Washers are high-vibration environments. If a wire leading to the heater or the NTC (temperature sensor) has rubbed against the sharp edge of the metal drum or the cabinet frame, the insulation can wear away. This exposed copper then touches the grounded frame, triggering the E68 code.
- Voltage Spikes and Control Board Failure: While less common, a significant power surge can damage the relays on the main electronic control board. If the relay that switches the heater “sticks” or leaks voltage internally to the board’s grounded mounting plate, the system will interpret this as a ground fault.
- Carbon Dust Accumulation: In older brushed motors, carbon dust from the brushes can coat internal components. Since carbon is conductive, a heavy buildup near electrical terminals can occasionally create a high-resistance path to the ground.
Troubleshooting & Replacement Instructions
Step 1: Safety First. Before touching any internal component, you must unplug the washer from the wall outlet. Shut off the hot and cold water supply valves to prevent any accidental leaks while you are moving the unit. WARNING: High-voltage capacitors can hold a charge; wait at least 5 minutes after unplugging before proceeding.
Step 2: Accessing the Components. Most Electrolux front-loaders require removing the rear panel to access the heating element. Use your Phillips head screwdriver or a 1/4″ nut driver to remove the screws securing the large metal panel on the back of the machine. Set the screws aside in a secure container. Once removed, you will see the large outer tub and the heating element terminals near the bottom.
Step 3: Visual Inspection. Look closely at the two heavy-gauge wires (usually red or white) connected to the heater. Look for signs of charring, melted plastic, or “arc marks” (black soot) on the washer’s frame. If the wires look pristine, the fault is likely internal to the heater itself.
Step 4: Multimeter Testing (The Critical Step). Set your digital multimeter to the highest Ohms (Ω) setting (preferably Megohms). Disconnect the wires from the heater terminals to isolate it. Place one probe on one of the heater terminals and the other probe on the washer’s metal chassis or the heater’s ground (center) stud.
Crucial Note: If the meter shows any reading other than “OL” (Open Line) or “Infinite,” the heater is leaking current to the ground and must be replaced. A healthy heater should have 0 continuity between the power terminals and the ground shell.
Step 5: Removing the Defective Heater. If the heater failed the test, use a 10mm nut driver to loosen (but not fully remove) the nut in the center of the heater assembly. This nut compresses a rubber gasket that holds the heater in place. Once loosened, push the bolt inward to decompress the seal. Use needle-nose pliers to gently wiggle and pry the heater assembly out of the tub.
Step 6: Installation and Reassembly. Slide the new heating element into the tub slot, ensuring it slides into the “bracket” or “hook” located inside the tub (this prevents the drum from hitting the heater). Tighten the 10mm nut until the rubber gasket bulges slightly, creating a watertight seal. Reconnect the wires, replace the rear panel, and restore power.
How to Prevent Error E68
To ensure this error doesn’t return shortly after your repair, implement these maintenance habits:
- Regular Descaling: If you live in a hard-water area, calcium buildup (limescale) coats the heating element. This causes the element to overheat locally, leading to the cracks that cause current leakage. Use a high-quality washing machine descaler or citric acid cleaner once every three months.
- Use High-Efficiency (HE) Detergent: Using too much non-HE detergent creates “oversudsing.” These suds can carry moisture into electrical connections and wiring harnesses, facilitating a path for current leakage. Always stick to the recommended detergent levels.
- Install a Surge Protector: Since the control board is sensitive to voltage fluctuations, plugging your washer into a dedicated heavy-duty appliance surge protector can prevent the relays from failing and triggering phantom E68 codes.
FAQ
Frequently Asked Questions
Q: Can I still use my washer if it shows E68?
A: It is highly discouraged. E68 indicates electricity is flowing where it shouldn’t be. While the machine’s safety software usually shuts down the cycle, there is a risk of electrical shock if you touch the metal cabinet while the machine is energized. Always disconnect power until repaired.
Q: Does E68 always mean I need a new heating element?
A: Not 100% of the time, but it is the cause in the vast majority of cases. Occasionally, a pinched wire or a faulty NTC (sensor) attached to the heater can cause the same leakage. Always test with a multimeter before purchasing parts.
Q: Why does the error only happen during certain cycles?
A: The heating element is only activated during specific cycles (like “Whites,” “Sanitize,” or “Hot”). If you run a “Cold” cycle, the control board may not energize the heater, and therefore might not detect the leakage immediately, though the fault still exists.
