Display shows E9 and unit will not start; often after storage or transport.

Safety first: Unplug the carpet cleaner before inspection.

• Check unit position: Ensure the cleaner is on a flat, level surface and fully upright. Some Electrolux models will not run if tilted excessively.
• Verify tank installation: Remove and reseat both the clean and dirty water tanks. Make sure they click firmly into place and that tank lids are properly closed.
• Inspect interlock switches: Look for small plunger or lever switches where the tanks sit or where the handle locks upright. Press them manually to confirm they move freely.
• Check wiring: Follow the wires from the interlock switches and tilt sensor to the main board. Reseat connectors and look for broken wires.
• Sensor replacement: If E9 persists and switches test correctly with a multimeter, the tilt sensor or interlock switch assembly may be faulty and should be replaced.
