Dish Washer causing RCD tripping

Thank you for the great help you give to others, really something which is highly regarded and commanded by anyone and appreciate your time and effort in all that.
I wonder if you could help me with my problem. We have got this Bosch SGS5022GB/20 dish washer for the last 9 years and were working fine. Suddenly, from yesterday, every time we try to start it cause the main RCP to drop and cut off the sockets power. It doesn’t cause the fuse to trip or anything just the RCP. Do you have any idea why is that and what would be the possible reason?
We found few drops of water underneath the dish washer which suggest some leak from somewhere.
thank you very much in advance

SOURCE: Machine fuses house RCD if a drying cycle is selected

Suggest you turn the power off, remove the top cover, diconnect the live and neutral connections to the dryer element (likely to be two of each flavour of connection if the machine has high and low dry settings). Pop a bit of insulating tape around the wire ends so you don't short anything out. Now try to put the machine through a drying cycle. If it works (albeit cold) without tripping the house power, you need a new dryer element. If the house power still trips, turn the power off again and without reconnecting the element wires, disconnect and tape the live and neutral wires from the blower motor. Again, try to run a drying cycle. If this stops the house power tripping, then it looks like a motor problem (though this would be quite unusual). If the house power still trips, you need to have a careful look at all the wiring between the main timer, the dryer timer, any hi/lo heat switch, the blower motor and the element with its associated thermostats and thermal cutouts (all located near the element on the air duct). Look in particular for chafes where wires go round corners, and where wiring crosses from the case to the suspended machinery in the middle of the machine. Pop any follow-on queries in the comments section of this question - I'll keep half an eye on it. A.

SOURCE: dishwasher trips the house mains

It sounds to me like you have got water in the Main wash pump, you need to turn of at the mains and put a meter across one of the main tags on the pump and the the other on the pump body, if you get a reading on the meter theres your problem. The only othere thing would be the heater which you can test in the same way.

SOURCE: hotpoint dish washer aquarius

I had the same problem with my Hotpoint Aquarius the eco and fast light flashing, it would go through the pre wash cycle and stop.
I cleaned the filters etc; and it still didn’t work.
I turned the machine off and unplugged it at the mains,
I drained all the water, turned the machine on the side and took the bottom off, I removed the drain pump off the bottom (this was held on with a single screw after taking the screw out slightly turn it to one side as its like a bayonet fit on a light bulb also remove the wire connection and a rubber drain pipe)
Once the pump was removed I could clearly see the impellor it was very tight and I couldn’t spin it after a closer examination I could see a foreign object jamming it I removed this with a pair of tweezers, replaced the pump and put it all back together and it now works perfectly.
I hope this can be of some help.
Peter.

SOURCE: hotpoint aquarious wd 440 two years old tripping main board

A faulty heater in both a washing machine and dishwasher will trip swithes because they both cause an earth........the chances are you heater needs replacing......the reason its tripping after a short period is probably beacause the cycle doesnt start heating the water until after approx 15-20 mins depending on the cycle chosen

Bosch diswasher,model Sms68m02AU trips circuit breaker


rcd units trip from the milliamps that are in a short
it trips the rcd to prevent electrocution and acts in nano seconds besides being a circuit breaker for excessive current
the trip can be from moisture allowing a current leakage to ground or some other simple operation
I suggest that you get in a qualified electrician / bosch service technician to find the reason for the problem rcd

Machine displaying general alarm the infuser slide was very tight freed up and reassembled now turning the machine on results in an arc at the motor brushes which blows the RCD breaker.


Hi Chris
Good Job freeing it all up etc. Your 90% there
Can you remove brushes & clean and stretch a millimetre more out of brush leads to stop arcing. Or perhaps the load is to great.
I did notice you said RCD.
RCD's usually only trip when an in-balance occurs between the hot phase wire & neutral wires.
Eg... what goes in via phase wire must come out on neutral wire. Even a small millivolt trickle to ground will trip an RCD. (20-30ma)
The Residual Current Device is for electric shock Safety.
It is not the main fuse or circuit breaker.
RCD's can be a real pain when there is a slight moisture leak.
For Example.
My fridge in my Winnebago would trip the RCD after it hadn't been used for awhile. The insulation around the 10A heating element was damp & tripping the RCD continually.
So how do I bypass the RCD to heat the element up and get rid of moisture. My method was to use a stand alone generator with no RCD to power the RV.
Worked great. Once the element surroundings were dry it ran fine on the home 240vAC.
So... If you really are tripping the RCD then the problem is AC "LEAKING" to Earth. Usually Moisture.....Try a hair dryer
If it is really blowing a Fuse or Circuit Breaker then the problem is too much current being drawn in circuit.
Hope this Helps

Advice on RCD tripping


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

Very often the washer trips the Rcd, but not always. Other appliance work fine on the same socket


If your washer works on a diffferent socket with a high load capacity then the trip happens only because the washer needs more current when it is loaded and so trips. So ignore if the washer works perfectly or else the controller unit / power supply/motor within must be checked.

My washing machine is causing the electricity to short when we put it on. Sometimes it runs for a few minutes and then it happens and sometimes it happens straight away. I did have to have a tube...


Water contamination on the electrical terminals will cause the washer to "Earth Out" and take out the RCD Household safety trip.
See where the contamination is and replace the contaminated items.
Hope that fixes your problem.

My Bosch Classixx 1200 washer causes the household RCD to trip


The first thing I would recommend u do is to remove the motor and check the carbons for wear, Their should be at least 3mm of carbon showing, any less then u shud replace.
The other possibility is a faulty heater element, u cud try it with the element disconnected, if it does not trip then the element is faulty.
Plz rate my solution.
thanks.

Hotpoint WMA 48, tripped house rcd, no lights on and water heating noise.


need to know a little more really but here goes, if you remove the top and the drive belt is still on then it will be as straight forward as the motor brushes at fault they will need replacing as this is a common fault on these machines. hope this helps
