Hello Doreen, my name is George.. This is normal, as the dishwasher only uses the Salt and Rinse Aid relative to the settings you have on the appliance... Do not worry about this unless you are starting to have problems with the finished wash.Kindly be patient whilst awaiting any responses from me as I'm not constantly available.
Do you require any further assistance Doreen? If so, feel free to ask... If not, can I ask you to rate the assistance in responding to your problem..
