Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the washer before removing the top cover.
- Locate pressure system: Remove the top panel. Find the pressure switch and its small rubber hose leading to the tub air chamber.
- Inspect hose and chamber: Check the hose for splits, kinks, or disconnections. Remove the hose and blow through it to ensure it is clear. If blocked, clean it and the tub air chamber connection of soap scum.
- Check wiring: Ensure the pressure switch connector is firmly seated and that wires are not damaged.
- Test cycle: Reassemble and run a short wash. If E11 returns, the pressure switch itself may be defective and should be replaced.
Incorrect water level sensing can cause overfilling or underfilling. If replacing the pressure switch does not resolve the issue, the control board may be at fault.
