Washing Machine
E63
The E63 error code on an Electrolux washing machine indicates a fault with the heating circuit — specifically, the appliance is detecting that the water is being heated when it shouldn’t be, or the heating element is running outside of its expected parameters. It’s a moderately serious fault that will prevent normal cycles from completing.
What does this error mean?
E63 signals that the washing machine’s control board has detected an unexpected voltage or current across the heating element — meaning the heater appears to be active even when the machine hasn’t asked it to turn on. This points to an electrical fault in the heating circuit rather than a simple component wear issue. Left unresolved, it can cause overheating, damage to your laundry, or further electrical damage to the machine.

🔍 Likely causes
🛠️ Step-by-step fix
Step 1 — Reset the machine: Switch off at the wall, unplug, and leave for 10–15 minutes. Plug back in and run a short cycle. A one-off control board glitch can trigger E63 and a full power reset may clear it.
Step 2 — Check the error is persistent: If E63 returns on the next cycle, the fault is genuine and you need to investigate further rather than keep resetting.
Step 3 — Inspect the wiring harness (visual only, machine unplugged): Pull the machine out and remove the back panel. With the machine fully unplugged, visually check the wires running to the heating element at the bottom of the drum for signs of burning, melting, or disconnection. Do not probe live components.
Step 4 — Test the NTC temperature sensor: The NTC sensor clips onto the heating element and is an inexpensive part (£5–£15). If you have a multimeter, a healthy NTC should read approximately 10,000 ohms at room temperature. A wildly different reading indicates a faulty sensor worth replacing before anything more expensive.
Step 5 — Replace the heating element if faulty: Heating elements for Electrolux machines typically cost £20–£45 and are a common DIY repair — the machine must be unplugged, the drum partially disassembled, and the element unbolted from the rear. Only attempt this if you are confident working with domestic appliance electrics.
Step 6 — Stop here if the element and sensor test fine: If both components check out, the fault almost certainly lies on the main PCB (specifically a failed triac). This is a job for a qualified appliance engineer — do not attempt PCB-level repairs yourself.
📞 When to call a professional
Call a qualified appliance engineer if the reset doesn’t clear the code, or if the heating element and NTC sensor both test as healthy — this points to a PCB fault requiring component-level diagnosis. When booking, tell the engineer: ‘My Electrolux washing machine is showing error code E63, which I understand relates to the heating circuit, and the element and thermistor appear intact.’ This saves diagnostic time and reduces your call-out cost.
⚖️ Repair or replace?
A professional repair for an E63 fault typically costs £80–£160 depending on whether it’s a heating element swap or a PCB repair/replacement. If your Electrolux machine is under 5 years old, repair is almost always worth it. For machines over 8 years old — especially if the PCB needs replacing (parts alone can be £60–£120) — compare the total repair cost against a new budget machine at £300–£400 and consider whether replacement makes more financial sense.
