the circuit boards from memory were about 270$ online. (if they repaired the two electrolytic capacitors they probably could have charged 400$ for 2 hours work and 1.20$ expense. but it would have required them to take the thing apart with the 50 screws and have a look inside. mind you the E6 fault meant communication problem between boards. hence they presumed two boards "blew to smitherins". but it can mean many other things, like for example a communication wire disconnected. incidentally the capacitors still had half the rated capacity when i measured them with the multimeter.
suppose i am still from the old school and like good quality things repaired.
yes if i turn on everything i will have overload too. the burners have different sizes, so depending the pan i use i use a different sized hob. i suppose if you have ten children and 20 relatives come to visit you might have to use all burners and the oven and the electric hot water heater. well, the hot water tank getting cold would stop them using the showers etc ....... hehehe
i got one of them small cheap induction transportable hobs too. it works alright, but the controls are not very good. like half way down, instead of regulating down it starts to turn on and off. so it boils, then starts to cool down for a while and boiling again.
you can get cheap chinese 4hob induction cooktops for 260$. however my thinking still is, i like to have good quality appliances. and i like them to last for a lifetime.
