Quick answer
A dark Miele dishwasher display does not by itself prove total power loss. Check for any response, then inspect the plug, outlet, and breaker from a dry, safe position. If power is stable but the dishwasher remains dark, or a breaker trips again, do not open the control area; arrange qualified Miele or electrical service.
Before you begin
Safety first
- Do not open electrical panels, probe live circuits, use a damaged cord, or repeatedly reset a breaker.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Press the normal On/Off control once and observe the display, indicator lights, and any response without changing several settings.
Expected result: The display or indicators wake, or everything remains dark and silent.
Next step: If it wakes, select a program and use the not-starting checks. If not, continue with the outlet and breaker checks.
Why this matters
Why: A response means the appliance has at least some control power; total darkness requires a safe incoming-power check.
-
Check 2
Inspect the plug, cord, and wall outlet from a dry position; test the outlet only with a safe known-working device and do not use an extension cord as a workaround.
Expected result: The outlet is dead, the plug or cord is damaged, or the outlet works while the dishwasher remains dark.
Next step: Use an electrician for the outlet or damaged cord and Miele service for a powered but dark appliance.
Why this matters
Why: A dead outlet or damaged supply is an electrical issue; a live outlet with no dishwasher response points toward the appliance power or control path.
-
Check 3
Check the labeled breaker and reset the dishwasher circuit only once if the panel and area are dry and safe.
Expected result: Power returns and stays stable, or the breaker trips again or will not reset.
Next step: Leave a repeat trip alone and arrange qualified electrical or appliance service.
Why this matters
Why: A single interruption may explain the dark display; a repeat trip is a protection response that should not be defeated.
-
Check 4
If controls wake but a program will not run, check that the door closes and a program is selected; observe whether the start indicator changes.
Expected result: The door latches and a program starts, or the controls wake but Start still does nothing.
Next step: Correct one accessible door or program condition once; request service if the control remains unresponsive.
Why this matters
Why: A powered dishwasher that will not start has a start-condition or control issue, not necessarily a power-loss issue.

Helpful context
Understand the symptom
Power and display are two different observations
First look for a response from the controls or indicators, then check incoming power. Keep the distinction clear so a display fault is not mistaken for a dead outlet or vice versa.
When checks do not resolve it
Need a professional?
Use qualified service for internal power, control, wiring, or door-interlock diagnosis.
Safety scope: Do not open electrical panels, probe live circuits, use a damaged cord, or repeatedly reset a breaker.
Have this ready
- Provide model, display and indicator response, outlet test, breaker behavior, cord condition, and door/start observations.
Common questions
FAQ
Does a dark Miele dishwasher display always mean no power?
No. Check whether any control or indicator responds, then test the outlet and breaker safely. A live outlet with no response points toward service.
What should I do if the Miele dishwasher breaker trips again?
Do not keep resetting it. Leave the circuit alone and use qualified electrical or appliance service, especially if heat, smoke, water, or cord damage is present.
