A few drops that build up after a wash cycle aren't an absolute emergency, but they're not something to ignore either. Whether it's "serious" or "can wait" depends on where the water's coming from. If it's leaking from the drain hose (the one that goes into the drain pipe), it might just be worn sealing or glue coming unstuck - in that case keep an eye on it and call a technician within the week. But if the water's coming from the inlet hoses (the ones going in, closest to the wall) or from around the front seal, that's where real problems start and you should act sooner.
At 6 years old your Candy isn't ancient yet, but it's starting to show signs of wear. Seals degrade, hoses get stiff - all normal stuff. In the meantime, try to figure out where it's leaking from: run a short cycle, stand there and watch, and see if the drops are coming from underneath (drain), from behind (inlet) or from the sides (seals). One thing to check: make sure it's not just condensation from the drain hose that isn't draining properly - that happens all the time and it's not a structural problem with the machine.
If it really is a small crack in the drain hose or a seal coming loose, you can handle it over the weekend. But if you notice the water's coming faster or if the amounts increase over the next few cycles, don't delay. And anyway, when you call, the technician will probably suggest replacing the inlet hoses (they're cheap) as preventive maintenance given how old the washer is - think about whether it makes sense to do it all at once.
