What E24 Means
Thermador documents this as a drainage problem involving the pump cover, hose, or airgap.
Common Causes of E24
- A clogged airgap fitting
- Debris under the drain pump cover
- A kinked drain hose
🔧 One Safe Check You Can Try
Clean the drain pump cover, check the hose for kinks, and clear any debris from the airgap fitting if your installation has one.
⚠ Why You Shouldn't Go Further Than That
- If all three checks come back clear and the problem persists, the internal drain path needs a technician.
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.
