No. Water can be expected in the reservoir according to the model's filling instructions. Its presence should not be confused with an unexplained puddle elsewhere in the machine.
Understanding this situation
Check the exact procedure before refilling and distinguish the salt compartment from detergent or rinse aid. Do not try to drain it simply because you expected an empty container.
A useful next step
Add only the specified product and amount as instructed, then secure the cap correctly. Follow the manufacturer's advice for any spillage. If the cap or reservoir is damaged, seek assessment rather than relying on repeated refills to compensate.
