Safety first: Unplug the carpet cleaner before any work. Do not operate with a suspected damaged cord.

Visual inspection: Examine the entire length of the AEG power cord, especially near the plug and where it enters the machine. Look for cuts, flattening, or exposed wires.
Flex test (unplugged): Gently bend the cord near the entry point and plug while checking for visible cracks or stiffness that suggests internal breakage.
Open cord entry: Remove the rear cover to access the cord clamp and connections. Ensure the strain relief grommet is intact and the cord is firmly clamped.
Check connections: Verify that the live and neutral wires are securely fastened to the terminal block or PCB. Tighten any loose screws.
Replace cord if suspect: If there is any sign of damage or intermittent connection, replace the entire power cord set with an AEG-approved replacement.

Never attempt to repair a mains cord with tape or temporary joins; this is a fire and shock hazard.

E15 appears intermittently; unit may cut out when the power cord is moved or flexed.
