Electrical Testing and Fault Finding - Socket NOT Working for a Dishwasher

Marcus and his work experience trainee Eric have been called out to a dishwasher that isn't working. On investigation through both electrical live and dead testing they find out that one of the conductor is broken. This broken conductor is causing the socket outlet for the dishwasher not to work. All the electrical tests are carried out using a Megger MFT tester.

Surely you would check behind socket to rule out loose connection on neutral

[michaelcostello]

Great video on fault finding principles. So easy to forget checking correct voltage and not just check live-earth. Thank you

[Dog-whisperer]

Fantastic. Demonstration of carrying out simple continuity test to find the fault . Also you need to replace the battery in your MFT as low battery power can give misleading test results.
Fantastic video Marcos as always👍👍👍👍❤️

A follow up video on this would be great 👍

[andrewyeo]

Five star service don't know of any other sparks that would do customers washing up. Lots of info to suggest neutral but what about when doing neutral to cpc continuity making sure switch is on at socket in case is a double pole switch not a criticism for great work

[tombickerton]

Great explanation of a step by step break down of fault finding. Learned a few tips on how to best use my megger mft

[ibrahimabdullah]

Loved it 👍👊 Thanks for sharing, more content like this please.

Thank you for focusing in on where probes are connected on the Megger and settings on the and intuitive to experienced testers, not necessarily to learners .Very helpful video.

[teyronjayneevans]

Fantastic, more videos on this topic please 🙏

[neilcowmeadow]

Thanks - logical and sensible faultfinding clip.

Hi, I am a little bit confused at 2:59 you read it as greater than 999 ohms but at the college, i was told it is 99.9 k ohms. Sorry this is not about me catching or something as I am a learner i am trying to understand. Great video on fault finding.

[alanmarriott]

Can I ask if it’s a broken neutral why is there voltage on neutral and also on cpc? Thanks

[lawrencer]

Why didnt you take the socket off the wall to check for loose cable ?
Very strange.
Less talking .
I wouid have checked from fuseboard to double pole switch, then double pole switch to socket..
Maybe get a proper spark to over see you 🤣🤣🤣🤣🤣🙉🙈🙊🥰

[pareshkumartandel]

why don't you use multimeter instead of megger
as its to understand for me
as mostly new people use multimeter

[carlchambers]

Pop the socket off, see the neutral terminals burnt out, replace socket, go home
