My EFa600H Stoves hob seems to be heating all rings too high. I used to put pots on bring to boil and then turn dial on hob to about 2/3 to cook things but at this setting it is still boiling and pots boil rapidly all the time. Even at setting 1 it is boiling. Is this the thermostat? Oven working fine and can bake etc. without this problem of overheating.
