My Kalorik iron is leaking water from the base, not from the iron. It is not overfilled, I have never used anything but distilled water, have replaced the filter. Any suggestions?

The feed valve is possibly stuck with build up from the water.
Try using distilled venegar to clear out the chalk deposits.

Probably not the filter.

If it is a new iron and the drops of water are excessive I would suspect it is faulty.

If the iron is well-used I would suspect it has a scale problem where localised scale build up is preventing some of the water from closely contacting the heated metal and turning to steam. This could be particularly true if you live in a hard water area.

Steam irons originally soon caused problems unless distilled or de-ionised water was used. It is reckoned modern irons can use tap water but hard water can still cause trouble.
A descaler additive might help but I haven't had good results in the past...

fill it with a solution of distilled water and white vinegar and let it soak for 24 hours. Then rinse it out a few times with distilled water and only use distilled water going forward.

Yes, it is ALWAYS best to use distilled water in any iron, no matter what a specific manufacturer may, or may not, say. The reason is simple: There's nothing in distilled water to contaminate your iron, and as a result, you will not have stained clothes.

If your iron is already dirty from using tap water... clean with mixture of vinegar and water by pouring mixture into iron, bring to full temp for a few mins, flush through steam vents, and rinse with distilled water. You may need to invert your iron to purge the water from tank as well. Repeat as many times as needed until perfectly clean.

Once clean, NEVER use any other type of water in you iron. Period. Always use distilled water. Hope this helps...

If the iron heats but steams improperly, inspect the soleplate and clean the vents (see below) and flush sediment out of the steam chamber .

If the iron produces too much or too little heat, test the electrical cord . Also test and, if needed, adjust calibration of the thermostat .

If the iron does not spray properly, inspect and clean the nozzle.

If the iron leaks or spits, clean the steam vents, nozzle, and tank.

If the iron sticks to fabric, clean or repair the soleplate. If the iron stains fabric, clean the soleplate, clean the tank with a commercial cleaner, and use distilled or filtered water.

God bless you

Leaking irons happen more frequently when performing lower temperature ironing. Minimize the chances of this happening by doing the articles that require less heat with a dry iron. When you're ready to do the articles that require higher heat settings, add distilled water to the iron after allowing it to cool first (some folks suggest using rain water as it will lack the minerals contained in the soil - where water pumped from the ground picks them up).

Distilled water is recommended by manufacturers for irons. Use of regular tap water will cause mineral deposits to form inside the iron that can build up and even clog the openings on the bottom plate. These can contribute to stains on the material being ironed, too. If you are unable to obtain distilled water, you ought to descale the iron regularly to remove deposits that will form by heating water or allowing it to simply evaporate. Distilled water lacks the minerals to be deposited by either of these situations. If distilled water is used - there is no need to empty the iron before storing. Tap water - whether supplied by the locality or a well is loaded with minerals and may be treated with fluoride, chlorine, etc.

Descaling an iron is pretty straight forward - no more difficult than descaling a coffee maker. Empty the iron of any water. Partially fill the iron with white vinegar and turn on to heat. Iron and old towel or rag to allow all the vinegar to pass through the steam openings.When empty, repeat once or twice - but with fresh distilled water to flush any remaining vinegar from the iron. When satisfied that the vinegar is out, store the iron. You can purchase products expressly made for descaling irons - just like you can for coffeemakers, but vinegar is a great low cost solution that works very well.

I hope this helps & good luck!

You need to clean it out, try a solution of white vinegar and water, if you can plug it in outside, do it. It usually is caused by tap water being stored in the iron and not emptied each time you use it. Once you run the vinegar solution through, rinse it out with distilled water, now only use distilled water in it plus empty it completely after each use. My iron is 40 yrs old and do this and never have a problem. I had wrecked other irons leaving tap water in it, so I know the problems it causes. I am hoping this will work for you, good luck, because it is cheap and worth a try.

The following web blog about Rowenta steam irons has some tips on maintaining the iron:

The following web blog explains the issue of not using distilled water:

I guess the bottom line is that it takes a higher temperature for distilled water to boil. It also explains that will cause the unit to spit, drip, and leak.
Try affordable spring water, and you should get better results.

I would suggest using distilled water, since something in the filtered water is producing the scale. If you switch to distilled, that should eliminate the scale.
Good luck, and hope this helps.

Run a mixture of white vinegar and distilled water through (don't iron anything) until the steam ports are clear. Run two loads of distilled water (until you can't smell the vinegar anymore) through. Use only distilled water in it afterward. That will help prevent scale build-up and avoid this cleaning process again.
