Water Softener (Some Models Only) - Fisher & Paykel DISHDRAWER DD24DI9 User Manual

The salt reservoir must always be filled with granular salt designed for dishwasher water
softening. We do not recommend the use of cooking salt like table salt, rock salt or pellets
as they may contain impurities that will damage the water softener. Do not add detergent
or rinse aid to the salt reservoir. This will cause damage.
