Built in oven (grill) tripping breaker

[MJPD29]

I think I understand where you are coming from @Pete999 and what is right is right. I think your comments were very much in line with the ethos of the forum and perhaps you were unfairly defamed there. It really is a difficult line to walk in advising others and thinking of the skill level of who you are advising and potential risks associated with that. Myself I guess it is the switch on the cooker and we could easily jump to the conclusion that it is the element which it very often is. However from what the OP says the trip does not occur when the grill is switched remotely. Therefore a piecemeal approach of try the element oh that didn't work. What else hmm? ah the switch, is for maintenance purposes a wholly unacceptable approach for a professional. As you fairly advised the person. You test and determine the problem then fix it in the most economical fashion. I think @Matthewd29 you might take time to consider encouraging others you have no idea about to undertake work that may be simple but could lead to harm no???

Im here to help it's up to them to decide whether they think they are capable or not. I certainly won't offer step by step advice to someone who hasn't got a clue but I'm happy to help with simple tasks

So, I've done a little analysis prompted by some of your replies. Results as follows:
1. The User Manual states that the oven should be connected via "Cooker Control Circuit". I'm guessing this should be a radial circuit dedicated to the oven? The electrician who did the wiring for our remodelling a few years ago has put our built in oven and microwave on a ring main, which I have to say didn't manifest as the problem it's become for a long time.
2. It is the RCD that trips when the oven is switched off after the grill is used. Additionally,I've only just been told this, but the problem only occurs when the oven grill is being used at the same time as the microwave.
3. I tried to replicate the problem by switching off at the socket outlet the oven plugs into. The breaker did not trip so only happens when oven is switched off via touch sensitive control panel.

Any clues chaps?

Yes get an Electrician to do some IR, and RCD testing as well as a load check on the particular circuit in question.

my money is on a momentary imballance L-N as the switch is operated, could be due to capacitive charge or other black magic electronics in the electronics of the oven.

Hello Willsie. Did you ever get to the bottom of this? We have an almost identical problem; the RCD trips when the oven grill is turned off. This seems to happen only when the (independent) hob is in use. The oven is plugged into a socket ring and the hob has a dedicated 32A circuit.

TIA

Thanks for the heads-up. They might still get an email notification though, right?

Possibly.
