What are solenoid coils and what are they used for
The solenoid coil is the electromagnetic component that controls the opening and closing of the steam valve inside steam irons and steam generators. When it deteriorates — due to short circuit, enamel short circuit or simple aging — steam stops coming out, comes out continuously and uncontrollably, or the appliance does not respond to the dispensing command. Replacing the coil is the first action to consider in these cases.

How to choose the correct coil
-
Exact brand and model: even within the same series (e.g. Polti Vaporetto) there are variants with coils of different voltage or geometry; the model code on the label is essential.
-
Nominal voltage (V): almost all coils in this collection are 230 V (European domestic use); always check that it matches the original.
-
Power (W): some models distinguish between coils of 6 W, 8 W or different values; the power affects the response speed of the valve.
-
Connector type and physical dimensions: the coil must be physically compatible with the valve seat in the appliance; if in doubt, compare the measurements with the original component.
Recommended maintenance
- Regularly descale the generator or iron: limescale deposited on the valve increases mechanical stress on the coil and accelerates its deterioration.
- Do not force the steam command if there is no output: repeated empty operation overheats the coil and can damage its winding.
- Always use demineralised or distilled water: impurities in tap water form deposits that clog the valve and force the coil to operate under abnormal pressures.
- Periodically check the coil connection cables: a loose or oxidised contact causes intermittent malfunctions that may be mistaken for a fault in the coil itself.
Common problems and solutions
No steam output
The coil has lost electrical continuity and does not open the valve. Check with a multimeter: if the resistance is infinite, the coil needs to be replaced.
Continuous and uncontrolled steam
The coil does not close the valve, often due to a short-circuited winding. It needs to be replaced; in the meantime, do not use the appliance to avoid burns.
Intermittent steam output
Oxidised connectors or partially faulty coil. First check the electrical contacts; if the problem persists, replace the coil.
Iron or generator not heating (Kenwood KCC90)
For the Cooking Chef mixer, the lack of heating of the induction cooking surface may indicate a faulty induction coil TB-000183; check with the service centre before replacement.
Quick FAQs
How do I check if the solenoid coil is faulty?
With a multimeter set to measure resistance (ohms): an intact coil shows a resistance in the order of tens of ohms (the exact value depends on the model). An infinite resistance reading (open circuit) indicates a broken coil; a reading of 0 ohms (short circuit) indicates a winding in short. In both cases, it needs to be replaced.
Can I use a coil with a different voltage than the original?
No. A coil with a lower voltage would burn out almost immediately; one with a higher voltage would not open the valve correctly. Always use a coil with the same nominal voltage (230 V for European domestic use) and the same power as the original.
Does replacing the coil require a technician?
For simple steam irons, the operation is accessible to those with experience in appliance repair: it requires opening the plate, disconnecting the connectors, and installing the new coil. For Polti and Rowenta steam generators, which operate at high pressure, it is advisable to rely on a qualified technician to ensure the steam circuit's integrity after reassembly.
