What E22 Means
Thermador documents this as a drainage issue involving the filter, pump, or hose.
Common Causes of E22
- A clogged filter
- Debris in the drain pump
- A kinked or blocked drain hose
🔧 One Safe Check You Can Try
Clean the filter, check the drain pump cover for debris, and inspect the drain hose for kinks.
⚠ Why You Shouldn't Go Further Than That
- If cleaning the filter and checking the hose don't clear it, the drain pump itself likely needs a technician's inspection.
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.
