    Hi all.

    Thank you all in advance for your help and advice.

    I was hoping to get some help and advice on a cooker issue I'm experiencing.

    My cooker is "brand new" and I recently had it installed by my father inlaw (competent tradesman although not an electrician)

    The cooker is brand new but actually 3 years old... this is because it's an ex display oven from a hardware store (wife works there)

    The Cooker will work fine for 20 uses. No issues whatsoever.

    But we have had 4 occasions where we haven't been able to use it.

    What was happening was we would turn the cooker on and it would trip 10 seconds later. Then we would put power back on then try again and it would trip 4 or 5 times before we sack it off for beans on toast.

    We were not using the hob at the same time.

    I will also add that when it happened last time the fuse wouldn't come back on. In fact most.times It trips for this reason I have to flick the fuse up multiple times.... that's another point it doesn't trip the rcd it trips everything at the fuse

    I found one website that suggested the fuse not wanting to come back on can suggest an earth fault.

    I was thinking maybe the wiring came loose in the back of the oven or the sockets maybe.

    It can't be the element cause it will work for 20 times on full load with not a single issue and the fact it's brand new really.

    I can't see it being an element issue but I'm hoping a knowlegable electrician may have an idea or a way to eliminate possibilities.

    The key points are
    • I can use the cooker most of the time
    • It mostly trips immediately but can be 90 seconds after powering up
    • I am not running anything at the same time
    • The power trips to the whole house but the fuse board where it is on a separate fuse remains in the "on" position when it trips the electricity.
    • When I try and flick the power back on at the fuse I sometimes have to do it 6 or 7 times for it to actually come back on.
    • The old cooker never did this so the mains wiring can't be faulty surely.
    I really appreciate any help. I am able to use it now but I did trip the power when I first turned it on tonight.

    Thank you all in advance and apologies of this isn't the right forum.

    Cooker is an AEG competence double oven.

    Could you post a picture of the consumer unit (fuse box/board), and explain what trips please?

    Do you know if there’s anything else on the kitchen spur circuit or is it exclusive to the cooker?

    RCD roulette. 30mA up front alongside a 30mA in the CU.

    Fault on the oven/wiring to the oven.

    Could it be a damp element again?

    Earth fault. The 80A rccb is slightly more sensitive than the 63 in the CU even tho both are 30mA

    An electrician will have test equipment to test the units, and the cooker.
    Ex shelf display models can be a little glitchy just with sitting in a shop. Dust, damp etc.

    You could be onto something here pal. Cooker was taken from a display kitchen 2 years ago. Been stored under the stairs since then. And was installed 1 month ago.

    Understairs cupboard isn't exactly damp.... but it was there a while.

    Is it just me or is the edge of that double socket sitting on top of the 45A DP Switch?
