Machine will not start a brew cycle; display shows E01 shortly after power-on.

Safety first: Unplug the coffee maker from the wall outlet before opening any covers. Never work on a live appliance.

Step-by-step checks:

• 1. Verify outlet and cord: Plug a lamp or phone charger into the same outlet to confirm power. Inspect the Electrolux power cord for cuts, burns, or kinks. If the cord is damaged, do not use the machine until it is replaced.
• 2. Check the power switch: Ensure the main power button is not stuck and has a positive click. Clean around the switch with a slightly damp cloth (machine unplugged) to remove coffee residue.
• 3. Inspect internal harness (advanced): Remove the top or rear cover (typically Torx or Phillips screws). Look for loose connectors between the power inlet, noise filter, and main control PCB. Reseat any loose plugs firmly.
• 4. Check for visible board damage: Examine the main control board for burnt spots, bulging capacitors, or cracked solder joints near the power relay or transformer. If present, the board should be replaced rather than repaired at home.
• 5. Thermal fuse continuity (advanced): Locate the thermal fuse on the heater assembly or wiring harness. Using a multimeter on continuity mode, test the fuse. If open, replace it with the same temperature and current rating.

When to call a technician: If the error persists after confirming the outlet, cord, and harness, or if you are not comfortable testing live circuits or replacing the control board, contact an authorized Electrolux service center.
