Calling all electrical professionals / boiler tradesmen -WE NEED YOUR HELP!

Every so often (twice in the last two days) when running the hot water in the kitchen it trips our electrics (downstairs lights, sockets, cooker and boiler) and cannot be reset for a good 20-30 mins. This only happens randomly and when running the hot water. We have unplugged all appliances except cooker and it still happened. We have had an electrician out who said all is good (EICR done in July 2023 and all good) and had plumber out to service boiler and also run through cycles of high fire and low fire with no issues (this was completed during the daytime,
Not evening).
We have had the water pressure sensor changed but no change to trips.
When having a shower in the evening it has not tripped the electrics, it only seems to be when using the kitchen hot water.
Any advice greatly appreciated.
Thanks
Jon
 
For an electrical fault you would be better off calling an electrician.
Thanks Dave. Just to note I have had an electrician out who says nothing is wrong, call a plumber who comes out and says it is electrical.

I think the below comment is correct in that I need to find a DECENT electrician!
 
Hi all. So the saga continues. We have had a new electrical company out. Fitted a brand new fuse board and yet the electrical
Sockets continue to trip. We have nailed it down to just the kitchen sockets but tripped again tonight. They said they split the circuit but they didn’t.
Only appliance on was fridge.
Was running hot water again and it tripped at some point.
Any ideas?

It is good news that you have an all RCBO board, that should help the electrician narrow down the fault.
 
Yes to the kitchen sockets. No further as of yet.
You know any decent fault Finding electricians in Cambridgeshire area 😂
Never know, if you let Artisan electrics do it on YT you might get it for free :tearsofjoy:

Edit: It should be getting a fair bit simpler to solve at this point though, limited to a number of sockets, and therefore cables.
We did initially think of them for our EICR but they were EXPENSIVE!
Always tempted by a freebie but not sure about my house featuring on YT if I’m honest.
 
Yes but I intentially tripped no4 and it didn’t kill any kitchen sockets?
So the whole kitchen (sockets) is on a 16A radial circuit?

Can you tell if the cables and pipework come into contact with one another at some point?

Hot water is just pressurised or gravity? No pump or heater involved?

Perhaps unplug every appliance on that circuit and see if it still trips but I'm sure the other sparks have tried that.

Being an intermittent fault it will be or can be difficult to locate.

I believe yes. I think they downgraded it from 32amp?

The hot water is from a combi boiler.
Can’t see any issues to the eye with wires etc.
