Tefal Ultimate FV9845 steam iron spitting brown marks
- The problem
- A Tefal Ultimate FV9845 steam iron, just over a year old, was leaving brown limescale-type marks on clothes when steaming.
- Likely cause
- The accepted reply said the most likely causes were limescale or rust deposits in the steam chamber, or residue such as starch or fabric conditioner baked inside. Internal corrosion or heavy scale was suggested if the problem persisted after cleaning.
- What fixed it
- Recommended action was to empty and inspect the tank water for sediment, clean the anti-scale collector or valve if fitted and if allowed by the instructions, run the self-clean/descaling function several times with clean water, clean the soleplate and steam holes, then test the iron on an old towel. If brown marks continued, the reply suggested internal corrosion or heavy scaling and said home strip-down was unlikely to be economical. The thread was marked solved, but no final user confirmation of the exact repair was provided.
- Checks to try
- Inspect tank water for cloudy water, flakes or brown sediment
- Clean removable anti-calc collector/valve if fitted
- Run self-clean/descaling function with clean water
- Clean soleplate and steam holes
- Test steam output on an old towel
- Parts or tools mentioned
- Clean water
- Soft cloth
- Suitable iron soleplate cleaner
- Anti-calc collector/valve
Safety: Isolate the appliance from the mains and let it cool before cleaning. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Brown spots from a steam iron are often either limescale/rust deposits in the steam chamber, or residue from starch/fabric conditioner getting baked inside. The good news is it’s often fixable.
1. Empty and inspect the water - Tip out the tank and check for cloudy water, flakes, or brown sediment. - If you’ve been using tap water in a hard-water area, scale is a likely cause. Tefal usually recommend checking the manual for the correct water type.
2. Clean the anti-scale system - If your FV9845 has a removable anti-calc collector/valve, remove it and rinse/clean it as per the instructions. - Soak only the collector if the manual allows it. Don’t guess with acids on parts unless Tefal specifically approve it.
3. Run the self-clean/descaling function - Fill with clean water, heat fully, then use the self-clean function over a sink. - Repeat a couple of times until no more brown water or flakes come out.
4. Clean the soleplate properly - When cold, wipe the soleplate and steam holes with a soft cloth. - If there’s burnt-on residue, use a cleaner suitable for irons. Avoid poking metal into the holes.
5. Test on an old towel - After cleaning, steam onto an old towel for a few minutes before using on clothes again.
6. If it still happens - Persistent brown staining can mean internal corrosion or heavy scale inside the steam chamber. That’s usually not economical to strip down at home.
Safety: isolate the appliance from the mains and let it cool before inspecting or cleaning any parts. If internal electrical work is needed, use a qualified engineer.
