We have developed an issue with our ceramic plated hob unit. It suddenly went off while in use, tripping the RCD.

No problem I thought, i'll just switch the RCD back to the on position, I think the hobs were turned off at this point but can't be 100% if i'm honest as I just called through to my GF to do it..anyway as I flipped the switch I saw a flash in the fusebox, accompanied by a bang.

Now I realise I should have switched the main power off before attempting to reset the tripped switch. Any idea's what i've damaged?

I can now reset the tripped switch, but as soon as i turn the switch on the kitchen wall for the hob power, it immediately trips it again without fail (no hob turned to on)

I understand the elements can be damaged from getting wet and cause issues like this, but it's tripping before I even turn a hob on making me second guess whether this would be the issue here.

Any insight welcome, i'm pretty much leaning toward replacing the appliance.

Sorry it's the MCB and RCBO that get tripped in that case.

Yes there are two switched on the wall in the kitchen, one for Oven, one for Hob. It's when I flick the Wall switch for the Hob that causes the trip. I've tried keeping the Oven wall switch off also but no change.

When it did first go, it took the oven out with it, but this came back on after a while.

I've been switching the RCBO to Off, then putting the MCB Labelled Hob back to On and then putting the RCBO to On again. It will stay there until i use the wall switch again.

I think I may need to get a pic up to accurately explain what the situation is. I'll get one up this eve which should make everything much clearer than me trying to explain! smile

OK, here's the fusebox:






This is what happens when i reset everything and then turn the wall switch on


Wall Switch - undone to check wiring looked ok
