What E14 Means
Thermador documents E14 as a flow meter failure or an issue with water flowing into the dishwasher.
Common Causes of E14
- A kinked or restricted inlet hose
- A partially closed water supply valve
- A failed flow meter part
🔧 One Safe Check You Can Try
Check the water inlet hose for kinks or visible damage, and confirm the water supply valve is fully open.
⚠ Why You Shouldn't Go Further Than That
- If the hose and valve check out fine, the flow meter itself requires a technician to test and replace.
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.
