RCD trips after different period of time

yes
an accredited electrician can test the circuits for insulation failure , vermin shorting across active / neutral/ earth points and the rcd itself
it is not a diy job

you cannot
The RCD unit works on an imbalance between active , neutral and the ground wire
the problem can be as simple as a moist connection, insect across terminals , wet dust , grease
the test is done by an accredited electrician using a correct meter to check insulation, wiring installation , elements and controls
you have done your best , now it is time to get it done safely

check the 13a fuse in the plug if you have a heater fault it may well have taken the fuse out as well as the rdc the machine will also need checking to resolve the issue rcd's are very sensitive with most having a trip current of only 30Ma although the heater is first thing to check

The clue will be when the rcd trips out. If everything is switched off on the cooker with the exception of the clock when you power it up and then it trips out, it could be in the wiring to the oven from the control switch and or the wiring in the oven. The only way you are going to find this is to take the oven out of the housing and test the wiring, isolating components until you find the problem.

this could be the hater or the motor but sometimes just chafed wireing
Common faults -
1 The heating elements can fail (meaning open circuit)
2 There are cut-outs (T.O.C's) that might need resetting
3 The thermostats (stats) can trip out or burn out (meaning open circuit)
4 Modern tumble dryers also have sensors and pcb's (Printed circuit boards) these have programs that can fail and circuitry although most should produce an error code showing you were the fault is.
5 Faulty connections and burned wires may also be the fault.

Hiya drodger, i had the same problem with my hotpoint dryer, (same company) if this is a condenser dryer make sure the drawer is collecting the water there is a small hole at the bottom of the drawer if you have a straw poke it in and clean it out, also at the back of the dryer there is a clear plastic pipe and a black one take them both off and clean them, your problem is exactly the same as mine so you will probably have to buy a new heating element (they are a lot cheaper from ebay) they are so easy to fit just 2 clips (i did it and im not dead yet!) hopefully you will then find the dryer will work perfectly, word of advice though clean the collecting drawer out at least once a month.
Hope this helps

Hi.
Try it with the heater disconnected, you will find it at the rear of the m/c at the bottom left behind a removable panel.
You may have to remove the top cover and the right hand side panel looking at the m/c from the front. Try it again.
I fit does not trip. then your heater is faulty.
If it still trips then you are probably going to have to call en engineer

it may not be the freezer. ground fault recept. are known to go bad pretty regular. upplug freezer and see if it still trips. It doesn't take much to trip one, so look for something simple

the fan element would have blown. it is not uncommon for an element to trip an rcd when it blows. you are on the right track, if you replace the element all your problems should go away

If the main oven is electric, disconnect the heater element and try, if no trip operqates. then replace element.
