What E11 Means
E11 means the water level in the tray or reservoir has read higher than expected.
Common Causes of E11
- Water inlet valve not closing fully, continuing to add water
- Reservoir overfilled during a service or cleaning visit
- Level sensor misreading due to mineral buildup
🔧 One Safe Check You Can Try
Check for an overfilled reservoir or a water inlet valve that may not be shutting off fully.
⚠ Why You Shouldn't Go Further Than That
- A water inlet valve that won't fully close is an active-leak risk, not just an inconvenience — worth addressing before it causes water damage nearby.
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.
