Washer shows E11 and stops; water may remain in drum or machine may not progress through cycle.

Safety first: Unplug the washer before removing the top cover or handling wiring.

Step-by-step checks:

• Secure pressure hose: Confirm that the small hose is firmly attached to both the tub and the pressure switch. Replace if hardened, cracked, or loose.
• Clear blockages: Remove the hose and blow through it. If blocked, clean or replace. Check the tub connection spigot for detergent buildup.
• Test the pressure switch: Use a multimeter to check continuity changes on the switch terminals while gently blowing into the port. If readings do not change, fit a new CDA-compatible pressure switch.
• Inspect PCB connector: Ensure the pressure switch plug is fully seated on the control board and that pins are not corroded or bent.
• Professional diagnosis: If a new switch and hose do not resolve E11, the PCB input circuit may be defective and should be evaluated by a technician.
