Quick answer
When a Smeg dishwasher is not working, first check whether the on/off indicator or display is blank, whether a cycle is selected, and whether the door is fully closed. Then verify the outlet and breaker, open water tap, program selection, and any delay-start or fault indication. Smeg notes that some models run a cold pre-wash and then wait for the scheduled time, which can look like a stopped dishwasher. Use the exact model manual for controls; if the dishwasher still will not start, a leak-protection condition appears, the breaker trips, or water and electrical parts are unsafe, stop and contact Smeg service.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Observe the control panel, on/off indicator, display, and any program or delay lights before starting another cycle.
Expected result: The panel is blank, the panel is lit but no program is selected, or a delay, fault, or other indicator is shown.
Next step: Follow the matching branch and record the exact indicator or display message for the model manual or service request.
Why this matters
Why: A blank panel points toward power; a lit panel without a selected program points toward the start sequence; a delay or fault indication changes the next check.
-
Check 2
Test the wall outlet with another appliance and check the dishwasher plug, accessible power connection, and circuit breaker without opening the appliance.
Expected result: The outlet is dead, the breaker has tripped, the plug is loose, or the cord or connection is hot, wet, or damaged.
Next step: Restore power only when the connection is dry and intact. Do not use a damaged cord or repeatedly reset a tripping breaker; contact a qualified electrician or Smeg service.
Why this matters
Why: A failed supply can leave the controls blank; water or visible electrical damage creates a safety condition rather than a user setting problem.
-
Check 3
Press the on/off control, select a normal program, and close the door fully as shown in the exact Smeg manual.
Expected result: The dishwasher enters program-selection mode and starts, or the panel stays inactive or refuses to start when the door is closed.
Next step: If the door will not close or the machine reacts only when the door is pushed or moved, stop and arrange service. Do not force or bypass the latch.
Why this matters
Why: The machine may not have been in program-selection mode, or the door latch, control, or interlock may be preventing a cycle.
-
Check 4
Check the water tap, visible inlet hose, and any leak-protection or water-supply indicator before starting the selected program.
Expected result: The tap is closed, the hose is kinked, water is present under the appliance, or the machine reports a water or leak condition.
Next step: Open the tap or remove only an obvious external kink when the area is dry and safe. If there is water under the unit or a protection indication remains, close the tap, disconnect power if safe, and call service.
Why this matters
Why: The dishwasher may refuse to start or may stop water intake when supply is unavailable or a leak-protection system detects a problem.
-
Check 5
Check whether Delay Start is active and whether the dishwasher has completed a cold pre-wash before waiting for its scheduled start time.
Expected result: A delay time or indicator is visible, or the machine briefly runs and then waits without a full wash beginning.
Next step: Use the exact model manual to cancel the delay or allow the scheduled cycle to proceed. If the machine does not respond to the documented control, arrange service.
Why this matters
Why: This pattern can be normal Smeg Delay Function behavior rather than a failed motor or control board.

Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
The display and on/off indicator are blank, and the outlet fails an external test or the breaker has tripped.
Do this next
Restore or have the supply checked when safe. If the outlet works but the dishwasher remains blank, contact Smeg service.
Why this path and its safety boundary
Why it matters: A household supply or power-connection problem is more likely than a dishwasher program issue.
-
PATH 02Next step
What you see
The panel is lit, but no program is selected or the door is not closing flush.
Do this next
Select a program and close the door normally using the manual. Stop if the latch is damaged, alignment-dependent, or requires force, and arrange service.
Why this path and its safety boundary
Why it matters: The dishwasher may not be in its start sequence, or door closure and interlock may be blocking operation.
-
PATH 03Next step
What you see
A delay indicator is active, or the dishwasher performs a short cold pre-wash and then waits.
Do this next
Cancel or adjust the delay through the exact model controls, or wait for the scheduled time. If the control does not respond, contact service.
Why this path and its safety boundary
Why it matters: Smeg's Delay Function is more likely than a no-start failure.
-
PATH 04Next step
What you see
The water tap is open and the controls are active, but a water or leak warning remains or water is visible under the dishwasher.
Do this next
Close the tap, disconnect power only if safe, do not bypass Aqua Stop or remove the base, and arrange Smeg service.
Why this path and its safety boundary
Why it matters: A supply, inlet, or leak-protection condition is more likely and may require access below the appliance.
-
PATH 05Next step
What you see
The outlet, door, program, water tap, and delay setting are correct, but the dishwasher still does not start after one documented reset.
Do this next
Stop user-level troubleshooting and contact Smeg technical support with the model, display state, selected program, and observed behavior.
Why this path and its safety boundary
Why it matters: A persistent control, latch, pump, wiring, or other internal fault is more likely, but the symptom does not identify a compatible part.
Helpful context
Understand the symptom
Separate no power from no cycle
A blank panel or absent on/off indicator calls for an electrical supply check. A lit panel that will not begin a wash can instead be waiting for a selected program, a closed door, water supply, or a delayed start. Smeg's current dishwasher guide places the appliance in program-selection mode after pressing the on/off button, then calls for loading, detergent, and a suitable program before starting it.
Check delay start before assuming the machine is stopped
Smeg says dishwashers with the Delay Function may begin a cold pre-wash after the door is closed and then stop until the preset time. Confirm whether a delay indicator or scheduled time is active in the display and use the model manual to cancel or change it. The exact control sequence is model-specific.
Verify water and leak-protection conditions
Check that the household water tap is open and that the inlet hose is not visibly kinked. Smeg product information describes Aqua Stop on some dishwashers as a system that can stop water flow when a leak is detected. Do not remove the base, bypass the protection, or work on the hose while the appliance is powered or leaking.
Use one documented reset, then escalate
Smeg customer-service guidance for its Belgian site suggests disconnecting an appliance from power for 10 minutes and restarting it as a possible reset. Treat that as regional Smeg guidance and use the exact model manual if it specifies another method. If the dishwasher remains inactive after one reset and the external checks, arrange technical support rather than repeatedly cycling power.
When checks do not resolve it
Need a professional?
Contact Smeg technical support or an authorised technician when the dishwasher remains inactive after the outlet, door, program, water-supply, delay, and one model-approved reset check; when the latch, power connection, or Aqua Stop condition is damaged; or when diagnosis would require removing panels. Provide the model code, display or indicator state, program selected, and whether the unit has power, water, or a leak.
Common questions
FAQ
Why is my Smeg dishwasher on but not washing?
Confirm that a program is selected and the door is fully closed, then check whether Delay Start is active. Smeg says some models run a cold pre-wash and wait until the scheduled time, which can look like a stopped cycle.
Should I reset my Smeg dishwasher?
Use one reset only according to the exact model instructions. Smeg's Belgian customer-service page suggests disconnecting the appliance for 10 minutes before restarting, but regional guidance and controls can vary. If the problem returns, arrange service.
Can I replace a pump, board, latch, or Aqua Stop part from a not-working symptom?
No. The symptom does not identify a compatible part or prove which subsystem failed. Smeg product information shows that models and features vary, so use the model manual and authorised service for internal diagnosis.
