CHECKING SANITIZER CONCENTRATION

Verify there is sufficient chemical supply in the sanitizer bottle and that the delivery tube standpipe is inserted
completely to the bottom of the chemical container. Place a glass rack, with glasses, in the machine.
Press the WASH key to run a cycle. At the end of the cycle, open the door.
Follow the directions precisely that are on the litmus paper vial and test the water on the surface of the bottom
of the glasses. Concentration should be 50 p.p.m. minimum to 100 p.p.m. maximum.
If reading is incorrect, contact your chemical provider for adjustments.

PRIMING CHEMICAL PUMPS

When a chemical becomes empty, the priming operation starts automatically the next time the machine is
turned on or a wash cycle is started. Note that the initial prime time for all pumps (Detergent, Rinse Agent,
and Sanitizer) is 60 seconds. If the chemical is not sensed within 60 seconds, the add chemical indicator will
flash. After the chemical is sensed, the indicator in the display turns off; and the pump continues to prime for
10 seconds to allow the chemicals to reach the machine. If all chemicals are empty, the sanitizer will prime first
followed by detergent. Only one chemical pump will run at a time.
If chemicals are not sensed after three consecutive priming operations, the add chemical indicator will flash
and priming is cancelled. The next time a wash cycle is started, the add chemical indicator will continue to flash.
Verify that the chemical bottles are not empty and that the delivery tube standpipes are inserted completely
to the bottom of the containers.
The priming operation can be reset by turning the dishwasher off, then back on.
If the chemical bottles are not empty and the delivery tube standpipes are inserted correctly, then the chemical
sensor or pumps may have malfunctioned; contact your local chemical provider.
