Zannusi FJS1225 Burning smell

Re: Zannusi FJS1225 Burning smell

Surely there are two issues here. Sorry Three…

1. When fault finding, there is obviously a need to test individual components because of double pole switching etc.

2. The Reason that this issue was raised in this thread was to establish whether sensitive electronics can tolerate 500v dc test voltages and I would say that they can.

3. We have a duty to meggar test any machine when the repair is complete and that should be done when the machine is back in its place under the worktop. (This obviously can not be done in all cases as the plug is often hidden.)

Does anyone have the relevant regs to hand to see what the correct answer is here? Does this come up in the PAT testing regulations?

I went on a course to bolton one time to be shown about the hoover backdragon version machines ( or whatever they were called) and the procedure I was shown was earth continuity then live earth and then nautral earth repair appliance select test programme and whilst water was still in the machine and switch on repeat said insulation test.O ye test motor and dryer part, as seperate so they certainly didn’t have a problem with megging electronic machines.My PAT tester on the other hand does short out the live nautral and tests it that way but I get more fails this way due to the capacitors discharging to earth so which is the safest way or best way ❓

If a garage does the MOT on your car and next day the brakes fail I don’t think they are responsible in law unless it can be proved beyond reasonable doubt that the fault was present at the time of the test.
Now I think the law relies on the test of reasonableness a lot. If the house you’re working in has modern circuit protection devices installed (RCD) then this, IMO, far out-performs the one off test you are doing with your megger as it’s there working away effectively constantly checking the appliance all the time it’s switched on. (With the important proviso that you’ve checked earth continuity as without that being intact a dangerous voltage could occur at the cabinet surface without causing the rcd to trip).(And even if a person then touched the cabinet wet through from the shower and in bare feet the rcd should save them).
The danger arises in houses with only an old style fusebox.
I agree with what Kevin(?) says about built-in appliances and indeed all wired in cookers.
If the plug is behind the appliance and inaccessible it would be wise to advise the customer to get a switch fitted above the worktop. Sometimes you just know you’re wasting your time though.

Perhaps this could be moved to its own thread ? very interesting topic ❗

http://www.pat-testing.info/index.htm

I have always used a Seaward PAT tester for checking an appliance for safety and for checking individual components for low insulation when reqiured. Always a great believer that an appliance should be checked for electrical safety when it has been completley assembled so no chance of catching live wires between metal chassis etc. ( talking from experiance), As kheath suggests though, this is a bit controdictive when testing a built in double oven for safety as you would need to pull it out to disconnect /isolate it to carry out a Pat test.

When we have machines repaired in the shop by the manufacturer that are under warranty, have not once seen an engineer carry out a PAT tester, and thats after a tub change 🙄

How many of you go to this trouble when you can change the fan oven element from the front I wonder ❓

Thought I’d let you know that after another two visits finally cured this one.. Transfered the drain hose to a sink outlet!… 😕

There was a leak on the oulet pipe where it went through the wall (been bashed by the garage door some 6mths before so customer thought irrelivent) and was leaking back into the house slightly, down the wall and under the floorboards into a elecrical junction box where it was tracking accross. All this happening behind the kitchen cupboard and inaccesible as usual as fitted by kitching fitter!. All just coincidental as it took till the fab cond rinse for the discharging water to build up and the junction box to start tracking. ❗

Changed oulet hose so it emptied into sink waste so no leak from pipe now no smell from washing machine/connector box… advised her to get electrician to sort out junction box and make safe and plumber to fix waste pipe (all will involve ripping out kitchen units… so finally a happy customer re. washing machine, not so happy re kitchen units… 🙄

Interesting points of view in the discusions about mega testing btw.. 🙂
