ModeratorOpen the new one up and it will give you a idea of where the tabs lock into place i never remove the oven to change these use a small pick or screwdriver to bend tabs

ModeratorLook in the instruction manual see if the basic settings are where they need to be also induction hob can trip the electric as anything that is connected to mains has a leakage to earth which can cause tripping i always advise type A circuit breaker

ModeratorIf you change the selector switch you won’t need to calibrate the touch controls, the test programme is only for bosch engineers and you use the finger to calibrate the touch controls

ModeratorCheck to see that you haven’t got a coun blocked in the pump impeller you can do this by removing the filter and shining a touch in where you have removed the filter make sure that the power is off before hand and you have towels to hand

ModeratorE56 is a communication error between power module and interface module it sounds to me like the power module fault as e51 is a motor wiring or motor fault
kaibart
ModeratorThat would be obvious when you start it you will just hear the relays clicking and the power modules on these do fail they are easy to fit aswell
kaibart
ModeratorYou can look on neff service down load manual
kaibart
ModeratorLook up the instruction manual page 27 onwards it will tell you how it comes apart in there use a plastic trim tool to remove metal tabs
kaibart
ModeratorMight need re calibration need test programme and tool for that
