Electric Installation Issues

Hi guys, i don't know what is going on, but there's something on my house whos constantly triggering the breaker, I called a technician to check what's going on, at first we suspected to be the washing machine, now we suspect the dryer, the fridge, and the heater. I just can't work like this, yes i have a UPS but that's for emergencies, is to safely turn off the computer.

Let's see if the expert founds the issue, right now my breaker is more triggered than an Twitter user XD
