Dishwasher SmartDispense Detergent and Poor Washability

Mixing an enzyme-based detergent with a chlorine-based detergent causes a gel-like coating on the bulk detergent dispenser tank sensor. This coating prevents the Low Detergent LED light from coming on. You will get poor washability, since there is no visual indication that the detergent tank is empty and that you need to refill the tank.

If you want to switch from an enzyme-based detergent to a chlorine-based detergent (or the other way around), the following routine should be used:

1. Once the Low Detergent LED light comes on, run an additional 3 wash cycles to empty the Smart Dispense detergent tank. The light will come on when there are 3 loads of detergent left. Running these three additional cycles will clear the tank of any remaining detergent.
2. Then, use the manual detergent cup for the next 10 wash cycles to make certain no residue is left in the Smart Dispense detergent tank.
3. After the ten cycles, you can fill the Smart Dispense tank with your new choice of detergent. At this time you can stop the use of the manual cup.

These steps must be taken when you want to switch detergent TYPE (enzyme vs chlorine). You do not need to follow these steps if you are just switching BRAND of detergent.
