E15 error message making a funny noise, is the a

E15 is a leak into dishwasher base. Leak can be as simple as using to much soap powder or a split lower spray arm to more expensive fix of a leaking sump base or wash pump. Need to pull dishwasher out of cavity, remove side panels and front kick panel and run machine and watch base to see where leak is coming from. Have had them leak from 4 main places. Heat exchanger where large plastic nut screws from inside. Bottom of wash pump. Plastic sump base (mainly towards front of machine. And last place is a small pin hole can develop in stainless base of machine towards front of dishwasher. Check soap usage and lower spray arm for splits first.

what kind of printer is it?

It means turn it off and on again, but this probably won't help. You get this message with a lens error, problem with focussing/zooming or whatever. Usually means there is grit in the mechanism or it has been damaged by a knock.

my hotpint aqualtis aqxxf149pi make a funny grinding noise when it spins help please?

The pump sounds like it may be plugged wih a coin or something like that. If the pump is plugged it will make a funny noise. Remove the pump and clear everything out of it

According to:

E15 means the Ink cartridge is not installed.

Both a black and color cartridge need to be properly inserted to clear this error.

Some Windows configuration file has been lost / got missing / got corrupted. What is the name of the file if i may ask?
