Washer-dryer combo displays OE1 and may stop mid-cycle with abnormal water level behavior.

Safety first: Unplug the unit and shut off water supply. Allow hot components to cool before working inside.

Steps to address:

• Inspect pressure hose and chamber: Remove the top and rear panels as needed. Trace the pressure hose from the sensor down to the tub connection. Remove the hose and check for soap scum or lint buildup. Clean the hose and the tub connection nipple thoroughly.
• Check for leaks: Examine the hose for pinholes or cracks that could cause incorrect pressure readings. Replace if damaged.
• Reconnect securely: Reattach the hose with proper clamps to avoid air leaks.
• Test operation: Reassemble panels, restore power and water, and run a test cycle to see if OE1 reappears.

When to stop: If OE1 persists, the pressure sensor or main PCB may be defective. These components require correct part matching by model number; consider professional diagnosis.
