Closing the door will start the wash cycle. At the end of the cycle, after the cycle
light has switched off, open the door and remove the basket. The cycle light will
come on at that point for a few seconds to reset the timer for the next wash.
- JET-TECH high temperature warewashers do not dump water and fill after every
cycle. The wash water is refreshed during every cycle by the hot
rinse water. Only excess water is expelled from the machine via the overflow
pipe. If the wash water becomes soiled, it is recommended turn off and drain the
dishwasher, clean
all debris from the filters and wash tank and turn on the dishwasher to
fill with fresh water
- Some models are equipped with an automatic drain pump (White button on the
front control panel) that will evacuate excess water. Please see the section
on: DRAIN PUMP OPERATION.
- During the rinse cycle, verify that Rinse Pressure is 30 PSI and that
the Chemical Flow Indicators are moving.
- IMPORTANT: If the dishwasher will not be used for two (2) or more hours, it should
be drained and turned off. The dishwasher should never be left in the “ON” position
