Washer shows E11 and stops; often associated with water level not detected correctly on Amica washing machine.

Safety first: Unplug the washer before removing the top cover.

• 1. Locate pressure switch: Remove the top panel and find the round pressure switch with a small hose attached.
• 2. Inspect hose: Remove the hose from the switch and tub/air chamber. Blow through it to ensure it is clear. Replace if brittle, cracked, or loose on fittings.
• 3. Clean air chamber: At the tub connection, check for detergent sludge blocking the air chamber. Clean thoroughly to restore proper air pressure transfer.
• 4. Test switch: Gently blow into the switch port and listen for clicks. Use a multimeter to verify contact change when pressure is applied. Replace the switch if it fails these tests.
• 5. Check wiring: Inspect the harness from the switch to the main PCB for damage. If all components are good but E11 persists, the PCB input circuit may be faulty.
