Why do people come on here and expect others to do all the thinking for them.? Only you can decide the answer to your question of replacing or repairing a 2 year old appliance based on the following:
1. How well you have looked after it and what condition it is in.
2. What it will cost to repair. Pick up a phone, call the service company and ask for a quote.
3. Cost of repair versus cost of buying a new appliance.
4. How much money you have to spare.

Depends on when it trips, not many parts, most likely is heater element, do a search for it, easy to get, next would be motors, more expensive, but depends whether better to get a new one, DIY, and save a lot on labour charges, so repair. Depends on engineer charges to fix, you would have to decide, Not difficult to change either part, start by disconnecting the heater element, if does not trip, them that faulty, replace
