MAINTENANCE
Maintenance and regular care is important to maintain optimal results with your Hobart warewasher.
DELIMING
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.
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. All LXe models are
equipped with an automatic delime cycle reminder. It is recommended that deliming be done when
DELIME RECOMMENDED is lit. LXePR and LXeR models are equipped with an internal delime pump
which will automatically pump the required amount of deliming agent into the unit.
If deliming is necessary, a deliming agent (such as Lime-A-Way
®
or LSR
®
) should be used for best results.
After the preprogrammed number of cycles has expired, the control will indicate the delime request
by displaying DELIME RECOMMENDED and will prompt ‘Would you like to delime now?’. You must
enter ‘Yes’ or ‘No’ to proceed with a delime cycle or to continue with normal machine operation. If ‘No’
is selected, the machine will continue to notify the operator at each start-up and power down until the
delime cycle is completed. To delime the unit:
1. Press the MENU/DOWN Arrow key until the ‘>’ symbol is shown to the left of ‘Yes’ and press the
ENT key.
2. Remove dish rack from machine.
3. Remove strainers from machine and clean. Replace strainers and close door.
4. On LXePR and LXeR models, ensure delimer chemical container is not empty. Be sure to push
the delivery tube standpipe completely to the bottom of the container. Check to make sure there
are no obstructions or kinks in the delivery tube.
5. Press ENT key to enter the delime mode. The machine will drain and rell with fresh water.
6. On LXeC and LXeH models, the display will prompt ‘ADD DELIME AGENT’ once the ll cycle
has completed. Open the door and add deliming agent. (Carefully follow supplier’s instructions.)
The sump holds approximately 3 gallons of water. On LXePR and LXeR models, the unit will
automatically pump in the required amount of deliming agent during the ll cycle.
7. On LXeC and LXeH models, after the deliming agent has been added, close the door. Press the
ENT key to continue the cycle. The machine will enter the wash mode for 10 minutes, then will
begin two rinse and drain operations. On LXePR and LXeR models, the unit will automatically
enter the wash mode for 10 minutes, then will begin two rinse and drain operations after the ll
cycle is complete.
8. After the deliming operation is completed, power to the control will be turned off.
9. Inspect the interior of the machine for lime deposits. If necessary, another delime cycle can be
initiated by entering the Manager Programming Mode.
LUBRICATION
The pump motor has permanently sealed bearings and requires no lubrication.
