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.
