Thermador Dishwasher E22 Error Code

Thermador documents this as a drainage issue involving the filter, pump, or hose.

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.
