My parents have been having trouble with their electrics recently. They had their house refurbished a year and a half ago and discovered some pretty awful DIY wiring from the previous owner so had a significant portion of the house rewired as part of the work. Despite this, they have been having problems. It's possible the issues have nothing to do with the wiring but they want to get it checked and they've asked me to call some electricians to see if they can come and take a look. When I call, they are asking me questions about the consumer unit and unfortunately it doesn't look like the one I have in my house so I'm struggling to explain anything to them.
In my consumer unit, there are two sets of MCBs with two RCDs and I expected something similar with theirs. Electricians are asking about the RCDs on my parents' unit and testing them but I can't see any. Each of the MCBs has an individual "test regularly" button but no specific RCD. It's proving hard to get an electrician out without being able to explain the situation to them clearly so any help would be greatly appreciated. In the image, the MCB on the left that is tripped/off is for the dishwasher, though everything else in the kitchen seems to be working fine apart from a faulty socket in the utility area (double socket with only one socket not working). The last one on the right before the mains breaker that is also off is unlabelled on the unit and is brown. Is that the RCD and it's just that the test button is on each individual MCB?
In case it's relevant, the current issue they're having is that the dishwasher keeps tripping plus one of the sockets in their utility area isn't working (double socket but only one side not working). The the side that's not working now cannot be switched off as the switch is stuck solidly in the on position (assume it has short-circuited but no idea why). I have explained to my parents that it's possible there is an issue within their dishwasher plus a faulty face plate on their socket and that it has nothing to do with the wiring and the two are not related.
Also worth noting that I will, of course,100% not be attempting any work on the consumer unit myself and will leave that to the professionals.
