Service manual

“Why are black marks showing up on the plates?”
There is nothing in the machine that makes black. Carbon black is the source of black specs and comes
from grill or hood fi lter parts. There are professional services that clean these kinds of parts. They should
never be clean in a dishwasher. Once the carbon black is inside of the machine, it is costly to remove it.
Cleaning hood fi lters or stove parts in a dishmachine is prohibited by FDA Food Code section 6-501.15.
Note: Plates that have lost the porcelain fi nish from stacking abrasion will have a dull white appearance at
the point of contact. This is the base ceramic material and is easily marked, just like chalk. The carbon
black will turn this ceramic grey or black. The answer is the plate should be replaced for sanitary reasons,
and grill components should not be washed in a dishmachine.
“Why are stem-ware glasses breaking in this dishwasher?”
Wine glasses have a weighted base and tip over easily when they are upside down, especially the popular
slim, tall glasses. The washing process requires mechanical action (spraying), temperature, chemicals, and
time. In an automated dishwasher, specifi c racks are made with compartments to hold the glass upright—
they are called glass racks. They are sized for the various styles of stem ware. Glasses should not be
washed using peg racks or fl at racks.
“Why is my machine foaming?”
Low water temperature (below 120°F) will cause the rinse aid chemical to foam. Use the least amount of
rinse agent to obtain sheeting on glassware. Temperatures of 130-140°F are recommended. This will make
your detergent more active and do a better job of cutting grease and food soil. This higher water temperature
will also shorten drying time.
Category 6, TABLES FOR CONVEYORS
“The soil table is too high and we can’t lower it to attach to the machine, racks are pushed in but the machine
won’t start, we can’t raise the machine any higher?”
The table is made to serve the machine process.
Existing tables may not be suited for new equipment and require replacement.
The dish racks must travel smoothly from soil table through the machine and onto the clean table to have a
successful conveyor installation.
ADS Installation Instructions state on the fi rst page that tables must rest on the machine lip and be secured
to the conveyor by bolting in place. This is required for smooth conveyor operations.
“The conveyor machine is installed in a small room, it has a short ‘L’ table on the clean side with a half-round
band for turning the racks, BUT they always stick half way and bunch up, how do I make them go all the way
around like they are suppose to?”
