I suspect your pump motor has been contaminated with LDS fluid which can seep in from over spills from the LDS tank. The oil then mixes with the worn carbon dust to create a paste that then causes overheating / shorting out.

Greetings,
Kees.
I will like to know what is the other 10 % means

Replace the fuse, and disconnect the electrical connections of the pump. Then start the car, rev the engine, and stop the car. If the fuse has blown again, it would suggest it is achieving a shirt to the body, so you'd need to look for damaged wiring between the fuse box and the pump.

Marc has 100% ,right!!
If this fuse has blown, this means the pomp motor turns to have, and because of this the power dissipate is much higher then!
The max power the fuse can handle must be below 480 watt.

Kees.

Thank's Man, one more question I have, ( is for everybody ) My pump motor is aparently gone (broken ). Do you (all) know where I can get a electric ( motor only ) for the pump, because new pump together is to expensive, my car doesn't cost that much. Maybe an online shop for French car parts where I can buy the electric motor only, Thank you

You probably need to take it apart and clean it up to remove all the carbon paste that is shorting it out.

Have a look at EDC5's guide here:

So you’re saying you’ve cleaned it all up and there is no power to the motor? Which fuses have you checked?

I don't say there is no power to the motor, there is but the motor won't turn, something is bad in it, I open it and I can see some melt plastic, I clean everything but does not start, when I connect directly to battery starts but turns slow, I don't want to open it again, it won't make any diference, just want to change it if I find one, thanks

Sounds like it has been overheating and has continued to be used, so has done more damage.
