SMEG cooktops
The one SMEG category with a real code table.
SMEG induction cooktops are the exception in the brand's quiet code policy: an officially published table of Er and E codes, built on the EGO induction modules used across Europe. Gas and ceramic SMEG tops stay mechanical - and get direct diagnosis.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.
Induction
SIMU series
SIMU315D domino through SIMU336D full-size induction.
Gas
PGFU low-profile
PGFU24X2/30X2/36X2 ultra-low-profile gas tops plus RTU rangetop-style models.
Ceramic
SEU radiant
SEU122B through SEU365ETB electric ceramic tops.
Format
Domino pairing
The 15-inch SIMU315D pairs beside gas - two small tops, one line.
Start with the symptom
Common SMEG cooktop problems
A symptom narrows the inspection; it does not identify the failed component. The $99 visit confirms the actual fault on the exact model before any repair is authorized.
Zones
Induction zone won't detect the pan
Pan material and size first, zone electronics second - the honest order.
Burners
Gas burner clicks forever
Moisture and cap seating on sealed enamel tops.
Symptom
Er21 in a hot kitchen
Ventilation under the counter matters - the code documents it.
Symptom
Ceramic element weak
Element and switch path on SEU tops - direct testing.
Surface
Cracked glass
Stop using the top; glass replacement is quoted honestly against replacement value.
Symptom
Domino pair half-dead
Each domino is its own appliance - diagnosed independently.
Series and model numbers
SMEG cooktop series we service
Induction speaks in documented codes; gas and ceramic speak through symptoms. Both are honest dialects when you know which is which.

Model numbers
SEU244ETB, SEU304EMTB
What to note
Radiant tops without a public code table.
Model label
Where to find your SMEG model number
The data plate is on the underside of the cooktop - reached from the cabinet below; a duplicate serial sticker shipped in the factory packaging. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
SMEG cooktop alerts & indicators
For any message not shown, use the manual for the exact model rather than a generic list.
Message / alert
Er03 showing constantly
What it means
The most common false alarm: liquid, a wet cloth or a pan resting on the control zone.
Safe check
Clean and dry the control area - Er03 that survives a clean panel is a touch-electronics visit.
SMEG diagnostics
SMEG cooktop error codes, decoded.
The induction table is official SMEG documentation, cross-confirmed by two independent service sources - a rarity for this brand. Gas and ceramic tops have no codes, and that is stated rather than papered over.
Error code · Er03
Control zone blocked
What it commonly means
A stuck key - liquid or an object on the sensors.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Clean first; persistent Er03 moves to touch-panel diagnosis.
Error code · U400
Supply over-voltage
What it commonly means
The top is connected wrong - over-voltage on the mains.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The connection is corrected to spec; an installation fault, not a component.
Error code · E2
Inductor overheated
What it commonly means
A zone's inductor overheated - classically an empty pan.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Cool-down first; recurring E2 with normal use moves to the inductor sensor.
Error code · E5 / E6
Mains signal / power board supply
What it commonly means
Wrong mains-voltage signal, or no supply to the power board.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Supply verification, then board diagnosis - a 5-minute power-off is the documented first step for E6.
Error code · E8
Cooling fan speed
What it commonly means
The cooling fan spins too fast or too slow.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Fan and sensing replacement - overheating follows if ignored.
Error code · E9
Inductor temperature sensor
What it commonly means
The zone's temperature sensor failed.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Sensor replacement per the official table.
Error code · EA / E4
Power board / configuration
What it commonly means
Power-board failure, or a configuration/communication error.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Board-level service with EGO-platform parts.
Error code · Er21 / Er22 / Er47
Electronics overheat / key evaluation / link
What it commonly means
Er21 clears itself below 75°C; Er22 is the key-evaluation circuit; Er47 the control-to-inductor link.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Ventilation review for Er21; electronics service for the others.
Any other code or behavior
Meanings vary by series and year
Why we do not guess
SMEG products span several control generations; the same characters can mean different things on different series. The complete model number fixes the definition.
What to capture
Photograph the full display and the model label, and note what the appliance is doing.
Next step
The $99 diagnostic visit confirms the actual fault before any repair is authorized. Book a visit or call (619) 877-6701.
Preventive service and owner care
SMEG cooktop maintenance
Alpha Pro provides preventive and general maintenance for SMEG cooktops. The appliance design determines which procedures are accessible and appropriate.
Owner maintenance
Routine care between visits
Burner cleanliness: keep gas ports, caps, and igniters clean and dry; reseat parts precisely after cleaning.
Glass surfaces: use cooktop-specific cleaner; avoid dragging cookware and sugar spills on hot glass.

Helpful answers
SMEG cooktop service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day SMEG cooktop repair in San Diego?
Yes - same-day windows are offered across San Diego County subject to the day's schedule. Availability is confirmed for the exact address when you book.
Does the $99 residential diagnostic fee always apply?
Yes. It is non-refundable and credited toward the total repair cost if you proceed. There are no residential exceptions.
What warranty comes with a repair?
A 90-day labor warranty and a 1-year parts warranty, both starting on the date the repair is completed.
Can a symptom alone identify the failed part on a SMEG cooktop?
No. A symptom narrows the search, but the diagnostic visit on the exact model confirms the actual fault before any repair is authorized.
What does Er03 mean on my SMEG induction top?
A blocked control zone - usually liquid or a pan on the sensors. Clean and dry the panel first; persistent Er03 is a touch-electronics repair.
What is U400?
Over-voltage from a wrong electrical connection - an installation fault. The fix is correcting the hookup, not replacing boards.
Where is the model number?
On the underside of the top, from the cabinet below - or on the duplicate sticker that shipped with the packaging.
Do SMEG gas cooktops have error codes?
No - they are mechanical with electric ignition. Diagnosis is direct: electrodes, valves, caps.
Why did my induction zone shut off mid-boil?
E2 overheat protection - often an empty or boiled-dry pan. Recurring E2 under normal use points at the inductor sensor.
