i have an old hotpoint aquarius dishwasher and i have bought a drying aid which says put in rinse aid box but i dont know where it is located please could you tell me
Many old dishwashers don't have a drying aid dispenser. If you have one, your will find some sort of cap to remove in the door, near where you place the detergent powder.
If you don't have one, you can buy an alternate vesion fo drying air, which is this little "basket" that you hang from the top rack. Avaiable in most stores.
