Tripping issue with Split load Wylex DB

[ipd1961]

Got an issue at home, today I got home and found one of the RCD's had tripped on my split load Wylex DB.
I tried to reset but it wasn't having it. Switched all MCB's off on the RCD (Call it number 1) that had tripped then reset. All was ok, switched each MCB on and stayed in.
Put the kettle on (which is on the other RCD (call it number 2) and on the kitchen circuit) and it tripped RCD number 1, kettle carried on boiling without an issue to the RCD 2 or the MCB it is on.

House was rewired in 2016 and the new board installed then

HELP, I am at my wits end which is a very short journey

Any ideas will be greatly received. Give me 3 phase any day of the week

Best you find a local spark with an MFT, an earth leakage clamp meter and time on his hands

Have you unplugged all items on these circuits?

Do you have the certificate from the installer ? That would be helpful for anyone investigating the issues

I had turned them off in the hunt for the fault. The ones off are the boiler, external lights and cooker

Have it to hand when a spark is investigating - changes in IR readings may be very eye opening..........

BUT have you unplugged everything ? Washing machines? Dish washers? Ovens ?

All items on the circuits on the RCD have been unplugged. But still it trips when anything on the kitchen circuit is switched on. We just tried each appliance in turn and each one tripped the RCD out. Weird the mcb and RCD that protects the kitchen circuits never tripped

Council property and all we got was your cooker is causing the issue. The cooker has been completely disconnected from the outlet and still it trips

The cooker was totally disconnected, washing machine dishwasher and tumble drier are on the kitchen circuit on the RCD that's not tripping. Just confused why after 2 years it's going ---- up
