your rcd is tripping because you have an earth fault on your washing machine i suggest you buy a new machine

The RCD tripping when using your washing machine could indicate that the electrical insulation/motor or other electrical component is breaking down causing the trip. It could be considered an early indication that your washing machine is failing. It could also mean your washing machine could be leaking and water tracking is causing enough earth leakage to trip the RCD. You could have your washing machine PAT tested to rule out a faultly washing machine.

As Adam suggests is the socket that the washing machine successfully works on also protected by the RCD. If the RCD is tripping then its not a load issue. If its the fuse or mcb then it is a load issue.

Is the other socket you tried (which the washing machine didn't trip on) on the same circuit? What else is on the same circuit?
Try unplugging everything else on the same circuit and just running the washing machine where it was.

Washing machines take a greater current than a dishwasher. As you do not know the difference between the current draw of a dishwasher compared to a washing machine, a DIY solution would be potentially dangerous. Therefore, I suggest that you get a qualified electrician to look at the affected wiring. RCDs are there to protect life!
