Hiya,
Is it tripping the RCD in the fuse box or one of the MCB's?
How did you check for an earth fault?
Thanks
Customer: replied 2 years ago.

multi meter by earthing one probe to earth then one on positive no reading then on negative no reading

Expert:  Techdesk replied 2 years ago.
Hiya,
OK, one probe to earth and the other probe the mains cable in?
If you simply try at the mains cable, it's only testing as far as the control board.
You need to test the individual components.
I also asked what was tripping, can you advise?
Thanks
Customer: replied 2 years ago.

the kitchen sockets and to test the individual comp is it just earth off chassis then try + and - on the various components and see if there is any reading on meter ?

???

Expert:  Techdesk replied 2 years ago.
Hiya,
OK, I need to know if it's the RCD or an MCB that's tripping.
Which is it?
Thanks
Customer: replied 2 years ago.

sorry it is the main circuit that supply's all the kitchen sockets I don't know what RCD or MCB are abbreviations are ? sorry

Expert:  Techdesk replied 2 years ago.
Hiya,
Main circuit?
Is it the one with a push button, marked RCD 30ma?
Thanks
Customer: replied 2 years ago.

when you plug in machiene its ok when you push on button on machiene it trips i then unplug the machiene go to fuse box and the one marked rccb 30ma has tripped when you flip that switch the mcb trips you flip that one on and its back to normal

Expert:  Techdesk replied 2 years ago.
Hiya,
OK, RCCB is the RCD.
That means you have an earth fault on the machine.
You can test the components (multi meter is a very basic test though, it really needs something like a megger to check the insulation of the machine).
or, you can disconnect parts to try and narrow the fault down.
Unplug it.
Take the top and side panels off.
Disconnect the heater first, try the machine.
If it trips, reconnect the heater and disconnect the motor.
Does it still trip?
When you have it apart, check for any loose wiring shorting on the cabinet.
Thanks
Customer: replied 2 years ago.

i will try that and get back to you you said a merger what is that

Customer: replied 2 years ago.

where is the heater it looks like a fridge inside

Expert:  Techdesk replied 2 years ago.
Hiya,
Can you check the model number please?
Neither of the 2 you posted is showing up
Thanks
Customer: replied 2 years ago.

dpu 8360w sorry

Expert:  Techdesk replied 2 years ago.
Hiya,
OK, thanks for that.
You have the heat pump dryer.
Disconnect the motor first.
If still tripping, disconnect the compressor (heat pump)
Thanks
Customer: replied 2 years ago.

disconnected motor still tripped replaced motor connector. then removed compressor no trip replaced red and grey wire no trip replaced twin ( red and green plus orange wire) to small round component that connects to the compressor via black wire then trips any help ?

Expert:  Techdesk replied 2 years ago.
Hiya,
Sorry, it's pointing to a faulty compressor.
The component you refer to I think is the starter for the compressor.
You could try obtaining one and fitting it to see if this component is faulty.
If you do and it still trips, it's the compressor.
If it's under 2 years old, I'd check with Beko to see if the machine has a 2 year warranty.
Hope this helps
Thanks
Customer: replied 2 years ago.

i have removed the compressor starter is there any way of testing this component

Expert:  Techdesk replied 2 years ago.
Hiya,
As I said before, you really need a megger to check the component insulation.
If your meter shows a circuit between the component and ground, then it would suggest it's faulty.
However, I've never had this before, it's normally the compressor.
Thanks
Customer: replied 2 years ago.

when i put the multi meter on the black wire of the starter all the conections show a reading is this correct as i dont want to buy starter just to see

Expert:  Techdesk replied 2 years ago.
Hiya,
Is this a test for an earth fault?
If not, then you'll get a reading through the coils.
If it's a test for an earth fault, you shouldn't get a circuit.
Thanks
Customer: replied 2 years ago.

when i remove all wiring excluding earth wire when i put meter on chassis and touch all connectors on comp is gives me a reading is that correct

Expert:  Techdesk replied 2 years ago.
Hiya,
No, you shouldn't have a reading.
It confirms that the item or the compressor (if the item is plugged in) is faulty
Thanks

on removing the earth from compressor all is working why is this and can it be run like this


 

Expert:  Techdesk replied 2 years ago.
Hiya,
Because you've removed the protection, the earth.

No, it's not ok to run it this way.
It has to be earthed so you don't get electric shock from the machine.

Thanks
Customer: replied 2 years ago.

even if it was only the one off the comp will the rest of the earths not earth the machine ? if it is so ill get rid thanks


 

Expert:  Techdesk replied 2 years ago.
Hiya,
By disconnecting the earth, you've removed the protection for the compressor.
The casing of the compressor is now live.

Thanks
Customer: replied 2 years ago.

thank you for your help


 

Expert:  Techdesk replied 2 years ago.
Hiya,
You're welcome.

Good luck with the appliance, or the new one if you decide to replace.

Thanks
