Beko BBIM12300AC Oven Trips Electric When I Turn On

July 23, 2025

Customer Question

Jeremy asks:

Every time I try to use my Beko BBIM12300AC oven, or even just the grill, the RCD on my consumer unit immediately trips, cutting off the electricity to everything. This is really frustrating; what could be causing this electrical issue?

Model: BBIM12300AC

I will try and help with this problem about Beko BBIM12300AC Oven,

Hi Jeremy, sorry to hear about to problem you are having with your Beko BBIM12300AC Oven. An oven that trips the circuit breaker only with the earth wire connected is indicating an earth leakage fault. This safety feature is triggered when electrical current escapes from a component and flows to the oven's metal chassis.

Common causes include a degraded heating element (Base Element, Grill Element, Fan Oven Element) that has developed cracks, or internal wiring with worn-out insulation that is making contact with the oven's frame. Less frequently, other components like the thermostat, selector switch or control board could be the source of the leak.

For a safe inspection, you must first disconnect the oven from the mains power. After that, you can visually check the heating element and wiring for any signs of physical damage or deterioration.

I've included exploded diagrams and videos on how to check and remove the parts from Beko BBIM12300AC oven that might help you. All part numbers and exploded diagrams are listed below. If you need any parts for your Beko oven, use your full model number on our website. If you need more help, feel free to contact me.

In the video, I mentioned about 5 common problems.;

  1. Oven will not heat because the element is faulty.
  2. Oven won't heat because timer on manual.
  3. Oven won't heat because of a fault with thermostat or selector switch.
  4. Oven not cooking evenly (one element faulty or fan not working correctly).
  5. Oven not reaching temperature normally an element but possible fan motor.

 

Coomon Problems with Electrical Ovens

  • The oven will not turn on

The first thing you need to check is that the oven timer is not on auto if it is, turn it on to manual.

  • No Heat in Oven

If the fan is running and the thermostat light comes on but you get no heat (or just the thermostat light on in non-fan ovens and cookers) then the probability is that the fan element or oven elements have failed.

  • Electricity trips (Rcd) when I turn the oven on or grill

This is normally an element that has gone to earth, This is a well-known fault with electric ovens, the insulation breaks down in the elements and trips the RCD , best way is to stick a meter on each element and check that they have not got earth leaks on them. But this can also be a wiring fault.

  • The grill element doesn't work

This would usually indicate that the grill element is faulty. Check these: Grill element, Oven changeover switch, Overheat thermostat, Main oven thermostat, if used to regulate the grill temperature.

  • The oven fan is not working or spinning correctly (slow) or is noisy

The fan motor may need to be replaced see video on this also the cooling fan motor can cause same problems.

  • The oven overheats and burns everything

Normally this is a simple thermostat failure which would manifest itself as this symptom.

  • The oven or cooker cuts out after it's been on for a while

This is an overheating problem which can be caused by the fan motor or main oven thermostat or a faulty safety thermostat that will be causing the problem. It can also be caused by a failure of the cooling fan, where fitted, but usually these go noisy before failing, Safety thermostats are used to prevent the oven or cooker overheating and will shut the oven down.
