DELIMING
WARNING: DELIMING SOLUTION, RINSE AGENTS OR ANY OTHER KIND OF ACID MUST NOT
COME IN CONTACT WITH BLEACH OR RINSE SOLUTION CONTAINING BLEACH USED IN
CHEMICAL-SANITIZING MACHINES. MIXING MAY CAUSE HAZARDOUS GAS TO FORM. THIS
ENTIRE PROCEDURE MUST BE FOLLOWED STEP BY STEP FOR SAFE AND SATISFACTORY
RESULTS.
CAUTION: Do not allow the deliming agent to remain in the machine longer than recommended
by the deliming agent manufacturer.
DELIME THE DISHWASHER ON A REGULAR BASIS AS REQUIRED. The regularity will depend on
mineral content of the supply water. 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 arms. LXi models are
equipped with an automatic delime cycle reminder. It is recommended that deliming be done when
DELIME flashes.
If deliming is necessary, a deliming agent (such as Lime Away or LSR) should be used for best results.
After the preprogrammed number of cycles has expired, which is factory-set for 1500 cycles, the
control will indicate the delime request by displaying DELIME. Machine operation will continue as usual.
To remove the DELIME icon, you must either enter a delime cycle or reprogram the number of cycles
to terminate the DELIME indication. (If the dishwasher needs to be reprogrammed, contact your local
Hobart authorized service office.)
1. Remove rack from machine. Close door.
2. Press OFF to power down the dishwasher.
3. Press and hold WASH (DELIME) while pressing ON. The display will show DELIME during the
fill cycle.
4. After the fill cycle, the control will prompt you to add delimer by flashing ADD and DELIME. Open
the door and add deliming agent. (Carefully follow supplier's instructions.) The sump holds
approximately 3 gallons of water.
5. After delimer has been added, close the door. Press the WASH (DELIME) key again to continue
the cycle. The machine will enter the wash mode for 5 minutes, then will begin two rinse and drain
operations. The DELIME symbol will flash in the display.
NOTE: DO NOT interrupt the cycle. Should the process be interrupted, restart delime procedure from
the beginning.
6. After the deliming operation is completed, power to the control will be turned off.
7. Inspect the interior of the machine for lime deposits. If necessary, repeat steps 3 through 7.
