Google recommended me an article about how to clean a detergent drawer and the first drawer shown was this.
I would dare to say it's an EU machine due the size of the drawer and the half load button.
But the bleach compartment throws me for a loop.
Something in my head screams Indesit for some reason, but that's just because they used to offer a bleaching function with a special insert you could use to turn the rinse cycle into a bleach treatment cycle.
So maybe they had that integrated at some point?
Have to say though:
Those grids are probably a pain to clean.
Only way to get them properly cleaned would be a brush of some sort and I can see that grate getting covered in sticky softner residue really quickly.
That's a good question! Since you - a veritable encyclopedia of knowledge - don't recognize it, I'm not surprised I don't either. My guess would be that it's a store brand of some sort - come to think of it, the closest I think I've seen in real life belonged to an old Matsui my grandmother owned at one time. It had the strange "net" with the logo for softener to pour through. I think some Indesit machines used to have a similar design, too.
