Don't know about the Candy but most fridges have a V shaped channel on the back wall that funnels the condensation out,they usually have a little plunger that you agitate to drain any water,food waste out the back.If it gets blocked the water can't drain,if the plunger don't work gently poke ti with a straw until it is clear.
