MAINTENANCE
DELIMING
WARNING: DELIMING SOLUTION MUST NOT COME IN CONTACT WITH BLEACH OR RINSE SOLUTION CONTAINING BLEACH USED IN THIS MACHINE. MIXING MAY CAUSE HAZARDOUS GAS TO FORM. THIS ENTIRE PROCEDURE MUST BE FOLLOWED
The dishwasher should be delimed when needed. Frequency of deliming will depend on the mineral content of the water supply. In areas where the water supply contains high concentrations of water solids, frequent deliming will be necessary. Deliming should be done when you can see clear signs of lime deposits (a white chalky substance) on the inside walls and on the wash/rinse arms. Inspect the machine interior for lime deposits. If deliming is necessary, obtain a supply of deliming agent (such as Lime Away or LSR) and follow the instructions on the package and the procedure below:
1.Make sure the machine is at the end of a cycle. Deliming is only possible after the completion of a normal cycle.
2.Remove the standpipe assemblies from the sanitizer, rinse aid, and detergent containers and place them as close to the floor as possible. Place a catch pan under them.
3.Press and hold the sanitizer priming switch until the sanitizer line is completely cleared. Repeat this step for the detergent and rinse aid lines.
4.Run the machine through two complete cycles, leaving the sanitizer, detergent, and rinse aid standpipes OUT of their respective containers.
5.Remove the dish rack from the machine.
6.Be sure machine has water in sump.
7.Turn the POWER switch Off.
8.Turn the DELIME/NORMAL switch (at the rear of the control box, Fig. 21) to Delime. None of the other machine functions will operate in the delime mode.
9.Open doors, add deliming agent to the water in the dishwasher, carefully following supplier's instructions. The sump holds from 1.7 to 2.3 gallons of water.
10.Close the doors. Turn the POWER switch On. The machine will run continuously until the DELIME/NORMAL switch is returned to Normal.

11.After the dishwasher has run for the recommended length of time, turn the DELIME/NORMAL switch back to Normal. The machine will complete its cycle in 90 seconds. CAUTION: Do not allow deliming agent to remain in the machine longer than recommended by the deliming agent manufacturer.
12.Inspect interior of machine for lime deposits. Repeat Steps 6 through 11 if necessary.
