Overview

Error code dE
Appliance Cooktop
Quick answer

dE is the demo mode indicator on a Miele hob; it can be deactivated from the controls.

Model compatibility

Miele reuses codes across series and model years, so dE may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Demo mode is activated.

What dE shows

Demo mode is on. It exists so dealers can demonstrate the hob in showrooms without it heating up.

At a glance

Code dE
What it means Demo mode is activated.
What you can check Demo mode is switched off through a button sequence on the hob. Sensor hobs use 0 and 2 held together for 6 seconds, while rotary hobs use the front left and front right controls turned anti-clockwise.
When to call a technician When dE cannot be switched off with the steps for your type of hob, a technician can help.

Sensor control hobs (no rotary controls)

  • Power the hob on and set induction-compatible cookware on it.
  • Tap 0 on any numerical display.
  • Hold 0 and 2 together for 6 seconds.
  • The timer display alternates dE with On or OFF for a few seconds.

Rotary control hobs

  • Hold the front left control turned anti-clockwise.
  • Click the front right control anti-clockwise twice, then hold it anti-clockwise.
  • The zone display reads dE when demo mode is active, or 0000 once it is deactivated.

Other messages

An overheating message is covered at E2; a fan fault at the fan fault codes.
