If you're living somewhere with hard water you're probably already used to the kind of issues you'll have, mineral deposits will build up over time and make it less efficient so you'll need to clean it regularly. I can't imagine vinegar would cause any damage but you should probably check the manual first, there could be maintenance instructions in there.

    Vinegar is supposedly relatively aggressive and can harm seals. Citric acid is better.
