What E27 Means
Thermador documents E27 as the supply voltage being too low.
Common Causes of E27
- A home electrical supply issue
- An undersized or overloaded circuit
🔧 One Safe Check You Can Try
Have an electrician check your home's voltage and the circuit feeding the dishwasher.
⚠ Why You Shouldn't Go Further Than That
- This is an electrical-supply issue outside the dishwasher itself, needing an electrician's diagnosis.
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.
