On just this small point of your post, this is probably a red herring.
There are several types of RCD - these are the most common you see in domestic, with AC being the most common until recently:

Some modern washing machines using inverter drives etc, can cause the AC type to not trip as quickly as they they should, because of the DC on the circuit. However, this is the opposite of what you are experiencing. Type A are generally recommended now because they can cope with this.
I'm not aware of washing machines being more likely to trip AC RCDs, though others more knowledgeable may know otherwise.

A picture of the board would really help. But does the washing machine not turn off when things 'trip'? If it does, then it must be covered by the RCD.
An RCD can cover several 'breakers' and circuits though.
If the washing machine stays on when the RCD/circuit breaker trips, then there is definitely something wrong with the house wiring (or vibration of a nearby cable by the washing machine, so indirect cause as has been mentioned)
Hi, apologies for the delayed reply.
I was advised by Bosch's technical department to have an RCD with the symbol under the A in your picture. My RCD doesn't have this symbol. I will attempt to get a picture of it.
I can confirm that the washing machine turns off when it trips. What I discovered yesterday was that the washing machine, microwave, kettle, fridge are all on one circuit. But the circuit breaker for this circuit isn't the one that is tripping. My board isn't labelled with "kitchen", "bathroom", "living room", etc. so I had to manually work out what was on each circuit (I didn't do this in all the years I lived here).
What I found was that the circuit breaker that trips when machine is in operation is not the circuit breaker that covers the circuit that the machine is on.
Those electrical devices I listed in my previous post are on the circuit with the breaker that trips. So that's why I am confused because up until yesterday, I thought the breaker that trips is the one responsible for protecting the circuit that the machine is on, but that isn't the case.
Yesterday afternoon, Apart from my TV, wireless router, and speakers, I unplugged all the devices on the circuit with the breaker that trips and ran the machine on a full load two hour 60C wash cycle, followed by an 800rpm spin. It completed both programs without tripping.
What I am confused about is that I only get trips when the machine is in operation. When the machine is not in use everything is fine - no nuisance trips, nothing. Logically when the machine trips the circuit breaker responsible for the circuit that the machine is on should also trip and cut the power. But the circuit breaker that trips and cuts the power is the one responsible for the circuit for those devices I listed in my previous post.
What I wanted to know is can the machine cause the circuit breaker on another circuit to trip? If there is a fault with the machine itself or the circuit that the machine is on, then surely the breaker for machine's circuit should trip. Instead the breaker with all those lower power devices I listed trips and cuts the power.
There is an important contradiction in your info that makes it impossible to advise further without clarification.
In post #1 you said:
Indicating that the RCD that trips feeds the circuit that the machine is on.
In post #24 you said:
Either the cycle was interrupted by the breaker tripping or it wasn't. The diagnoses are completely different.
It is possible for an appliance to trip an RCD that does not feed it. The implications are:
1. The likely cause is a neutral-earth fault on a circuit protected by the RCD that trips. It could be in the wiring or an appliance plugged in, which need not be switched on.
2. There is no indication of a problem with the appliance that triggers the trip event, nor the circuit that it is plugged into. It is simply the peak load current (not earth leakage) of the appliance causing the remote, faulty circuit to leak to earth.
3. An electrical test of the affected circuits will almost certainly locate it at once.
I know what my next move would be...
Hi, sorry for the delayed reply.
Up until yesterday I presumed that the circuit breaker that was tripping every time was responsible for the circuit that the washing machine is on. The breakers aren't labelled and in all the years I've lived here I never bothered to work out which breaker is responsible for which set of sockets and lights, etc. in my home.
I decided to do this yesterday morning and I discovered that the microwave, washing machine, kettle and fridge all sit on one circuit, but the actual breaker that trips when the machine is in operation isn't the one responsible for the circuit that the machine is on.
Instead the breaker that actually trips and cuts the power is the one responsible for the circuit that all those devices I listed in my previous post are on.
I only have this intermittent tripping problem whenever the machine is in operation and when it is in the last 30 minutes of the two hour wash cycle. It can't just be a coincidence that I only get a trip when the machine is in use.
From what I've worked out yesterday, I found that the breaker that trips definitely isn't the one responsible for covering the machine.
The machine still loses power and goes off, but the breaker that actually trips covers a different circuit (the one with all those low power devices I listed).
Logically shouldn't the breaker for the machine's circuit trip if there is an issue with the washing machine?
I don't what to make of it. Could it be that there is a lot earth leakage from one or more of those low power devices and the machine's "natural leakage" causes the breaker on the other circuit to trip?
I didn't think this was possible, but from reading your post it sounds like it is possible for the machine to trip the breaker on another circuit.
I guess the next step isn't going back to Bosch, but calling electrician to find out what's going on.
Many thanks
