I am looking for a cap for my tefal pressing profile steam generator iron model 2880 can you help

Polti have many models. All question need 'make model (what it is)' as the first 3 words in every question. Otherwise it is a but of a guess.

If it is getting hot, then it should be producing steam. There can only be on reason and that is that something is blocked with limescale. Has it ever been descaled?

If it the type that has a hot flat iron and a hose to a steam generator tank, then it is possible that the element has failed. It is worth descaling that unit as well just in case there is a blockage down there. Add the descaling solution and turn it on for 5 minutes. Turn it off, leave 5 minutes and give it a shake every 5 minutes for 30 minutes. The descaling solution will only remove scale from places the solution touches.,

Spray it with WD40, and let it soak in. Remove with a cloth. Put vaseline on the threads. Don't over tighten.

I assume it has water in it. Is it set hot enough to generate steam and is it getting hot, if not check your breaker or fuse. Try these links for more help:

time to junk it
the holes and controls are badly corroded internally

Try using CLR cleaner, if not just buy a new one, and keep the receipt for a return down the road, these iron's are reasonable nowadays.

strait vinager fill it to full let sit over night then empty

I would empty the water out and attempt to flush it out and steam some C.L.R through it

Run white vinegar through the iron over the sink with iron on high & steam button pressed down. This should dissolve any minerals that build up in it. Then run water through it over the sink to rinse the vinegar out.

try ascetic acid instead of the cartridges
