My steam cleaner spits water instead of dry steam
Home Nura guide — category: Steam Cleaners
Diagnosis
A steam cleaner that spits water is really producing wet steam, meaning the water condenses before it leaves the nozzle. The most common causes are an appliance that has not fully heated, an overfilled tank, or limescale that disrupts the heating.
Possible causes
- Used before it reaches full temperature — the steam is not yet dry, so droplets of water come out of the nozzle.
- Tank filled above the maximum — water is carried out with the steam instead of staying in the boiler.
- Limescale in the boiler or nozzle — it reduces heating and narrows the outlet, causing uneven spitting.
- Long or cold hose, or wet attachment — steam condenses on the way and arrives as water.
Recommended steps
- 1Unplug the unit and let it cool completely before refilling; never unscrew the cap while it is hot or under pressure.
- 2Fill only to the maximum mark, using the type of water the manual specifies, then wait for the ready-to-use light.
- 3Aim the first few seconds of steam at a cloth to clear condensed water before cleaning the surface you want.
- 4Descale the boiler and nozzle using the method in the manual, sticking to the approved product and rinse times.
- 5Unroll the hose fully, avoid wet attachments, and drop to a lower steam setting if your model has one.
Repair or replace?
If water spitting returns straight after a proper descale, the boiler or valve is probably damaged. On an older unit, replacement parts often cost nearly as much as a new model, which would also be safer.

Frequently asked questions
Usually, yes, if the failure shows up during the warranty period and isn't caused by misuse. A product in the Steam Cleaners category bought new from an authorized retailer normally comes with a manufacturer's warranty: check its length in the manual or on the brand's website. Consumer protection rules also vary by province and territory, so keep your proof of purchase.
If you're still within the store's return window, a return or exchange is usually the fastest fix. After that, the manufacturer's warranty takes over: its customer support can arrange a repair or a replacement. Even outside the warranty, the manufacturer can often repair the device for a fee. Either way, keep your proof of purchase.
Our public methodology lowers the Nura Score /10 of any model in the Steam Cleaners category whose recurring failures are documented in owner reviews. A model that breaks down too often never tops our rankings, whatever the brand.
Generally, yes. Routine maintenance, such as cleaning, replacing a gasket or recalibrating, is part of normal use and doesn't usually affect your warranty. Irreversible changes to the hardware are what can cause problems. For a product in the Steam Cleaners category, stick to the steps described in the manufacturer's manual and read the warranty terms before going any further.
When a product fails in its first few months of normal use, the cause is usually a manufacturing defect. Contact the seller or the manufacturer with your proof of purchase and a description of the symptom: for a model in the Steam Cleaners category that is still under warranty, this is the typical case for a free repair or replacement. Warranty terms vary by brand, so read yours.
