Washer-dryer shows E11 and may stop with water still in the drum or fail to progress between stages.

Safety first: Disconnect from mains before removing the top cover.

• Locate pressure switch: Remove the top panel and find the round or rectangular pressure switch with a small hose attached.
• Check hose and connections: Ensure the hose is firmly attached at both the switch and tub end. Look for splits, pinholes, or kinks.
• Clear blockage: If accessible, remove the hose and blow gently through it to confirm it is clear. If blocked, rinse it out and refit securely.
• Inspect switch connector: Reseat the electrical connector on the pressure switch.
• Test cycle: Reassemble and run a short wash. If E11 returns, the pressure switch itself may be faulty and should be replaced with a Bush-compatible water level switch.
