2) Cold water supply, hard dried soil problem

D. Poor drying
check
Bad performance in plastic cups
- Recommend the customer choose “Sanitary option

- In plastic cup , it’s very difficult for drying because
of the characteristic in plastic.
Plastic is some oily , so the function of rinse aid
( reduce water surface tension ) can not effect
on plastic. ( water can not be spread ).
- Plastic is high resistance of heat capacity
( This is the reason why we use the handle of the
fan and pot as plastic ), after cycle dishes are
very hot but plastic cups are warm.
so this characteristic can make very difficult
for good drying result

5.How to adjust leg
Installation improvement
NOTE ;
When you adjust the rear legs, use care to turn the adjusters in the proper direction.
These adjusters may be damaged by being driven in reverse at the upper stops.
Turning the adjusters the wrong way when the leg is fully retracted will produce a loud snapping sound
to alert you that it has reached the upper limit.
If you use an electric screwdriver, keep the torque setting as low as possible to reduce the possibility of
damage to the adjusting mechanism.
In the event that a rear adjuster is damaged, you can adjust the leg manually as before by removing the
broken adjusters.

Applicable Serial No. :Refer to the below
SUBJECT : PCB replacement SVC to correct ‘HE’
error code
Background
1) During the production date specified below, programming errors have been identified
that cause the units to display an ‘HE’ error code. New boards have been developed to
correct this problem.
Resolution:
On the affected models, within the specified serial range, replace the main PCB board.
This will resolve the issue.
Note: As this is a programming error we advise to replace the board on these units even if
the initial call is not due to an ‘HE’ error, this will prevent the issue from occurring in the
future.

SUBJECT : Improvement of installation (Worm Gear Strip)
Symptom Details
○ Issue:
-Rear leg worm gears stop working after multiple adjustments.
○ Reason:
- The strength of the gear is too weak for lifting the product multiple times (Mold: Nylon POM)
Improvement:
- .Changed gear material from Nylon POM to Zinc Alloy (Improved Strength)
-. Changed the shape of the parts (Improved Strength)
Additional Modification to base on all models needed from 810KWxx~ 102KWxx:
-. To use new parts on the old base some modification to the base is needed (see
page 3 - Apppendix.2)

To use the new worm gear parts on the old base you will need to modify old base to
allow for clearance.
Before:
Remove rib
After:
Rib removed
• Put gloves on to prevent injury
• Using a utility knife, remove the rib located on the back side of the rear foot hole
(as illustrated above).
• Note: If replacing both rear feet worm gears the rib will need to be removed from
both sides.

Guide rib
Improvement:
-Only if there is no guide rib in the filter assembly,
Change to a filter assy (good part) with a
guide rib.
You don’t need to change filter assembly,
if there is a guide rib in the filter.
-When you do SVC , you must adjust twisted
check valve with your finger to correct it in
sump assembly. If not, poor washing will
continue.
