Action
•
Check that all drain filters are correctly installed and that the drain handles
are in the DRAIN CLOSED position.
•
Check that the water supply is turned on.
•
Check the dirt trap(s) in the water inlet(s) and clean them if necessary.
•
Check the float switches in the tank(s). If the switch(es) are dirty or coated
with chemicals or lime deposits, they may not function correctly. If they are
dirty, clean or delime the interior.
•
Check that the water supply is turned on.
•
Check the line strainer in the cold (rinse) water inlet and clean it if necessary.
•
Check for lime scale deposits on the final rinse arms. These deposits can
clog the final rinse nozzles. Delime if necessary.
•
Check that the curtains are correctly installed.
•
Check that the tank float switch assemblies are clean.
•
Check the steam supply (if so equipped). The machine is set up to operate
correctly with the steam volume and pressure that are present during
installation. Low pressure and/or volume may affect performance.
All rack conveyor dishwashers release some steam at the ends of the machine.
However, if steam is excessive, check the following:
•
Check that the curtains are correctly installed.
•
Check the final rinse temperature on the digital display (FR) to ensure that
it is operating at the correct temperature.
•
Check that the end caps are correctly installed at the end of all prewash
and wash arms.
•
Check that all auxiliary rinse and final rinse arms are correctly installed.
•
Check that the curtains are installed properly.
•
Check that the ware is correctly loaded. Refer to the Operation section of
this Manual.
•
Check for correct detergent and rinse aid concentration.
•
Check for excessive mineral content in the water supply. Meiko recommends
a hardness of 4 grains per U.S. gallon.
•
Check that commercial (not domestic) detergents and rinse aids are being
used.
•
Check for correct detergent and rinse aid concentration.
•
Check that heavily soiled ware is being correctly pre-scrapped. Excessive
amounts of grease or soiling in the wash tank can cause foaming.
•
Check that the tank temperatures shown on the digital display are correct.
