Micro/Oven Combination Built in oven tripping whole board

[lushlol]

I have recently completed renovations in my kitchen and installed a Miele Micro/Oven Combination. However, when I turn on the grill or the oven - the appliance trips out the entire flat.

When I first installed the appliance, I had this problem when turning the oven to 200 degree C, and it only happened after about 1 to 2 mins. However it seemed to resolve itself and I put it down to dust on the elements, and I have been able to bake and roast without an issue. However, this weekend I tried to use the grill for the 1st time and again, it tripped after 1 to 2 mins. Now when I try to use either the oven or grill - as I turn it on - it trips instantly. I can use the microwave function without any issue.

I had the electrics for the cooker rewired and signed off. The cooker switch has over it 32A. The details on the certificate are 1 phase, Nominal Voltage 250V, nominal freqency 50Hz.

From my very limited understanding this seems to be what is required for my appliance: mains cable 50Hz, 230 - 240V single phase.

I have tested and there does seem to be 1 wall socket that is attached to this fuse switch on the box as well as my cooker.

My builder says that the problem is the appliance, however it is new (though has been sitting unused for some time now) and I dont know whether it is or not. I am starting to think it is - but was wondering if anyone has experienced a similar issue or has any advise to offer me?

thanks!

It could be any one of a number of things - faulty cooker, loose connection, earth fault on the circuit or on the cooker, etc etc.

There's not much else you can do but to have both the appliance and the circuit tested by an electrician.

Can you get the electrician back who installed it for you? He'll know how it was installed and will be able to test it quickly.

When you say it trips out the whole flat, do you mean everything - lights and sockets, or just sockets?

Have a look at your fuse board in more detail and see if you have a funny looking trip switch which is called an RCD. Is this what is tripping, rather than any of the individual trip switches?

If it's the RCD tripping then you'll likely have a different problem to if it's the individual trip switch.?

Can you look inside the door of your oven/grill and read off how much power (kW) it requires? It may be that it is too much for the trip switch that covers is and that's why it's tripping. What is the current (A) written on the trip switch which supplied your oven/grill

More info please!
