Quick answer
Smeg dishwasher noise can come from the pump, spray arms, circulation motor, dishes, or installation. A single click or water sound can be normal; scraping, grinding, or a sudden loud change calls for service.

Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Note whether the sound occurs during fill, wash circulation, drain, drying, or door movement and remove any loose dish that could vibrate.
Expected result: The symptom location, timing, or control response is clear, or another symptom is present.
Next step: Continue with the next documented check only if the area is safe; otherwise stop use and arrange qualified service.
Why this matters
Why: Smeg dishwasher noise can come from the pump, spray arms, circulation motor, dishes, or installation. A single click or water sound can be normal; scraping, grinding, or a sudden loud change calls for service.
-
Check 2
With the machine off, check that spray arms rotate freely and that the filter and racks are seated without touching the arms.
Expected result: The accessible condition is corrected, or it is normal and the original symptom remains.
Next step: Continue with the next documented check only if the area is safe; otherwise stop use and arrange qualified service.
Why this matters
Why: The result narrows the fault to an external condition or leaves a model-specific internal fault unresolved.
-
Check 3
If the noise is scraping, grinding, electrical, or suddenly louder, stop using the dishwasher and arrange service.
Expected result: The appliance operates normally after the check, or the symptom returns or creates a safety concern.
Next step: Continue with the next documented check only if the area is safe; otherwise stop use and arrange qualified service.
Why this matters
Why: The result narrows the fault to an external condition or leaves a model-specific internal fault unresolved.

-
PATH 01Next step
What you see
The dishwasher making noise clears after the permitted filter, door, inlet, drain, rack, or programme check.
Do this next
Monitor the next normal cycle and keep the exact model manual available.
Why this path and its safety boundary
Why it matters: The result fits an owner-accessible condition documented by Smeg; the symptom does not identify a part.
-
PATH 02Next step
What you see
The dishwasher making noise returns after the external checks or the exact manual does not cover the display.
Do this next
Leave the dishwasher off and arrange Smeg or qualified service.
Why this path and its safety boundary
Why it matters: A model-specific pump, valve, latch, sensor, or control fault remains possible.
-
PATH 03Next step
What you see
Water reaches the floor or electrical base, smoke or burning odor appears, or the door cannot be controlled safely.
Do this next
Close the water supply and isolate power from a dry location, then obtain qualified service.
Why this path and its safety boundary
Why it matters: This is a water or electrical safety boundary.

What the first check tells you
Smeg dishwasher noise can come from the pump, spray arms, circulation motor, dishes, or installation. A single click or water sound can be normal; scraping, grinding, or a sudden loud change calls for service.
Use the exact model guidance
Smeg publishes model-specific instructions for the dishwasher. Preserve the full model identity and use the opened support or manual page before disassembly.
When checks do not resolve it

Stop use for active leaks near electrical parts, smoke, burning smell, repeated breaker trips, unsafe movement, or a symptom that returns after the model-approved external checks; arrange qualified service.
Common questions
FAQ
Can I keep using a Smeg dishwasher with this problem?
Use it only when the owner-level check clears the symptom and there is no leak, heat, smoke, electrical damage, or unsafe movement. A recurring symptom needs qualified service.
Does this symptom identify one replacement part?
No. Record the exact model and observed result first; use the model manual and service diagnosis before selecting any part.
What information should I give service?
Provide the full model, the making noise symptom, when it occurs, what the external checks showed, and any photo or short recording.
