I find that it's never really worth doing call outs for things like dishwashers because most of the time these days it's just gonna be cheaper to replace it from the start. 2 call outs from 2 different people will probably cost the same as a cheap new dishwasher, and the engineer coming out will probably just say it needs replacing. I'd just tell em get on Currys, buy a new one and fit it themselves and save their money. If it's something like an oven do a quick DIY resistance test on the elements using any meter and if those are fine then don't bother investigating more, new oven it is. Ovens are like £200 for a decent one now, no point in gambling calling someone out and if they do find an issue then they need to order a part and then come back, and 2 visits plus cost of parts will be more than £200. How many times have you been to a job where somethings tripping specifically when something like an oven or washing machine is being used and it actually turned out to be the wiring to the appliance?
An insulation resistance test from the cabling supplying the dishwasher at the spur may reveal a high resistance short. Also offer to remove the fuse and let them see if it still trips.
Why don't customers empty the cupboards where they know the electrician will need access? Maybe the professionals who watch this channel could make a mental note - mention it when booking the job. My gas engineer mentioned that (for the annual service to comply with the warranty) he would need to get at the water filter on the heating circuit; "it will be just under the boiler" he said. It took me an hour to remove the shelf and contents that had been built in units underneath the boiler and I found the filter behind. He said that this happens a lot and, as he charges for the time it would take to dismantle everything, it can add quite a chunk to the bill on top of the servicing fee.
I feel for the electricians and plumbers who have to come in at a later date to do repairs on refitted kitchens, really I do, but even I as a lowly domestic cleaner have as many frustrations in my job, because in SOME (and I must emphasis not ALL) situations the only requirement seems to be that as long as the kitchen stays standing long enough for the fitters to leave, the job is a good 'un. It never looks good when lights fall down, shelves collapse, cabinet doors drop, or plinths pop off, and all because someone had the job of wiping it all over as part of a normal, regular, cleaning routine. One bathroom I used to clean had been fitted the the fewest amount of screws as possible, with each and ever wall mounted accessory being held in place at its lowest point with a blob of clear silicon. It didn't take long for all that to be swinging all over the place as soon as it was touched.
Those mains tails look like they are entering the C/U in separate entry holes ? Surely in a metal C/U that can create arcing and should be entering together via a proper grommet ?
Alright delroy, I've had it before, the screws at front bottom do the feet normally at back and front , so you can pull out dishwasher, also on same job the socket right behind dishers, the plastic moulded plug had melted as but up against back of dishwasher .
What I would of done is put a plug top on the load cable from the spur and stuck that in the pat tester. Atleast it might of gave you a bit more information.
