How do i rinse out,lack of steam

You should only use distiller water in the steamer. Never ever use tap water! This is what caused lime and scale build up.
Since it's to late, you have nothing to loose by trying this to descale the unit:

Put up to one cup of white vinegar into the reservoir. Fill 3/4 of the way with water. Turn unit on and let it heat up, but DO NOT RUN STEAM THROUGH THE LINE. Once heated up, turn unit off and let it set for hours. Drain and rinse well. Then run a water only batch through the steam cycle. There are companies that sell special de scaling solutions. But hopefully, the vinegar will work.

Hi, Brown water and whitescale are often the result of the water you use in the iron... If you have scale, white vinegar will clean that... For brown water, empty the iron, rinse out the insides with bottled water, and then use the bottled water instead...

sounds like it is time to de-scale the iron to loosen all the deposits inside the unit.
add some white viegar to the water ( which should be distilled water ) and heat up and let the iron steam out the solution. now add just water to the unit shake it and rinse out with water and drain. now do one more vinegar / water de-scaling and rinse out again. now fill with just distilled water and let it steam out and now your iron should be clean as new.

THE LINK DOESNT SEEM TO WORK SO HERE IS THE INSTRUCTIONS FROM THE MANUAL.

Cleaning the Boiler
To extend the life of your steam generator and to avoid any build
up of scale, it is essential that you rinse out the boiler after several
hours of use. If your water is hard, increase the frequency.
Do not use descaling agents for rinsing out the boiler, as they could
damage it.
1. Check that the appliance is cold and unplugged for more than 2
hours, and that the removable water tank (1) has been removed
from the steam generator.
2. Place your appliance on the edge of your kitchen sink.
3. Unscrew the boiler drainage plug (15) located on the bottom of the
appliance using a coin.
4. Holding your steam generator in an upside down position, and using
a jug, fill the boiler (in the base unit) with 1/4 litre of water
5. Shake the base unit for a few moments and then empty it completely
over a sink or bucket. To obtain the best result, we recommend
that this operation is done twice
6. Important: before reclosing, make sure no water remains in the
boiler.
7. Replace and tighten up the boiler drainage plug with a coin

There is commercial iron cleaner, but you can use white vinegar and distilled water to flush it. I would use a mixture of half and half. Then let it steam its little self, when it is clear, rinse with the distilled water again, This kind of thing happens when you use tap water and let it sit in it without rinsing after using. I always use distilled water and empty right away after use. Good luck

Put in as much white vinegar as possible and then turn iron on. Let it stay on for about 30 minutes the try the steam button. Once the steam button begins to work empty the vingar an fill with distilled water to rinse. You'll need to rinse several times to get all of the vinegar out.

Hi,
Here is a tip that will help you with that problem...

1/4 C. Apple Cider Vinegar : 1/4 C Water
Pour into the iron and let it steam through; have anything that you want to have a permanent crease -- like pleats in a skirt or the front seam of slacks? The vinegar/water mix will make it a strong pleat. When pleated skirts were the fashion in the 70's, I had a white gaberdine skirt and used clear vinegar to avoid any discoloration, and the pleat would not quit!

Once you have filled up with water and always just below full line, if your model has one, you need to press the "reset" or "restart" button on the back end of the generator (the end furthest away from the water container). Also, do be sure to regularly descale as advised above otherwise the water/steam can't get through.

there is most likely a small port where some particles have clogged...fill reservoir with vinegar and water (50/50) and allow to soak 24 hrs, then reheat then shake vigorously to drain then rinse then retry
