My Phillips GC8600 series steam iron has stopped steaming mid iron. None of the tips in the manual are the problem

SOURCE: Brown spots coming from steam iron

you can mix 50% water with 50% vinager let it set in the iron overnight then turn it on and let the steam run out.What happens is the inside of the iron where the water is had corroded or rusted or has lime deposits.the vinager will break this loose overnight.also after you let the iron steam out all the mixture,flush the iron 4 to 5 times and start using fresh water from a store bought gallon.your tap water is probably full of iron.

SOURCE: No steam

It appears that your rocker switch is broken, I am attempting to find a source for the switch and the screw driver that removes the screws holding the unit together

Fill with 50/50 water vinegar solution. Get it good and hot and let it sit for two hours. Rinse and repeat if necessary. Buy a gallon of water from the market and use that from now on. This will fix your problem. The Iron is concentrating the iron in you water and this is what is causing the brown spots. Hope you find this helpful. If you do please take the time to rate it fixya and maybe I will keep helping people for free.

If you are having steam problems then the cartridge needs changing.

I phoned them (0161 652 1211) and they do sell the cartridge for £5.99 including delivery but are out of stock for a couple of weeks. You have to send them a cheque or postal orders. Good luck.

Send Cheque for £5.99 for each cartridge with note of model etc.

Your steam generator my have mineral deposits that are clogging the steam openings. One of the easiest things to do is to pour out the water and add white vinegar. Let the vinegar sit for about 2 hours. Then turn on the iron and press the steam button until the deposits are loosened and flushed by the heat and steaming vinegar. Do this on a towel or other absorbent fabric so you don't stain your ironing board. You may need to unplug the iron, let it cool and then gently **** the steam vents with a wooden skewer or toothpick.
I hope this helps you. If it does, please rate my suggestion!
