What DE Means
DE means a door has been open past the timeout — informational, not a mechanical fault.
Common Causes of DE
- Door left open or ajar past the timeout
- Door seal has degraded enough that a closed-looking door still reads as ajar
🔧 One Safe Check You Can Try
Close the door fully and check that a bottle or shelf isn't propping it open even slightly.
⚠ Why You Shouldn't Go Further Than That
- None — this is an informational reminder about a door left open, not a mechanical fault.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
