Replacing 10A Fuse with 16A Fuse for 1900W Dishwasher & 2800W Oven in Late 70s Apartment

Hello,
I'm not an electrician, hence my question.
I live in a block of flats from the late 70s, I have 3 16A automatic fuses in the apartment (a washing machine and a gas-electric hob with a maximum power of 3000W are connected to this circuit); 10A (all kitchen appliances use this circuit); 6A (lighting). Recently, I was doing a renovation in the kitchen and I found out that my oven and dishwasher are connected to a circuit with a 10A fuse. The dishwasher has a power of 1900W, while the oven has a maximum power of 2800W. I think the 10A fuse is a bit too weak. I've already used the oven and everything was fine, nothing broke, maybe it didn't reach the max. power, but I'm a little afraid, because it seems to me that I should replace this fuse with 16 A. And my question is this - Can I have 2 fuses of 16 A in the apartment and this one 6 A? I have the main fuse in the hallway and it's 25A.
I know that I cannot use the dishwasher and the oven at the same time, so as not to load the circuit, as well as the washing machine and both heating points on the hob.
I should add that the wires in the apartment are copper with a cross-section of 2.5 mm
Thank you for your return.

If the wires have a cross-section of 2.5 mm 2, use a 16 A fuse for sure will not hurt. Only if someone gave 6 A there, is there 1.5 or 1 mm2 for sure. If the cross-section is smaller, it will not work without forging walls and laying new wires. Regards, ŁP

Maybe a friend has 2 16 A fuses, nothing will happen. The point is not to consume more current than 25A because this is the allocation of my friend

Thank you for your answer. I remember not to exceed those 25A. The wire cross-sections on these two circuits where there is a 16A fuse and on the second 10A I have 2.5mm2 for sure, and the third 6A fuse is only for lighting. I had the installation replaced 10 years ago. Yesterday I carried out the entire inventory of the installation in the apartment, because I was not sure which circuit my oven was connected to. Because I had relocated and added sockets, so I did not know which circuit was used. Now I know, that's why I want to screw in a stronger fuse. I just don't know why when testing the oven, I turned it on to max. temperature and this long program did not break this 10A fuse since at this max. 2300W if I'm not mistaken.
Sorry for such simple questions, but for your own safety .... I have some doubts about my professionals..
Regards

The current is expressed by the formula: I=P/U*cos(phi)
In your case, it only slightly exceeds 10A. In addition, the oven does not consume this electricity continuously.
Another thing is that the fuse does not blow immediately after exceeding 10A, but after some time, which results from its characteristics and depends on the current value.

If you are sure that you have wires with a cross-section of 2.5mm`2 on this circuit, then you can confidently give 16A protection.

Thank you very much for your answer, so I am replacing this fuse.
