fuse box is interrupting circuit

[do9b5n6l]

Hi folks.

• 1980s 1bedroom apartment
• old fuses (not breakers)
• several 220V 50hz stoves/ovens

With all fuses engaged, if you turn a burner up past half way or several on at the same time (and/or the oven), something trips (CHUNK! sound) at the fuse box which interrupts the (GREEN ASTERISK) circuit (fuses don't blow) I've determined that if I disengage a certain fuse, (RED ASTERISK) stoves can draw what they need.
Questions:

• Am I correct in assuming this is not something I can easily fix? We cannot leave the other (RED ASTERISK) 10amp fuse disengaged permanently because it is part of the hot water heater circuit.
• In the stove's manual, there are some figures in watt hours which represent consumption I think but I don't know how to calculate to determine if the draw is more than the 32amp circuit can handle. (landlord is trying to say our stove's are the problem but I'm 99% sure they are not - Previous tenant had a wonky setup with gas stove I suspect because they couldn't get electric stove to work either)

Thanks!
