6000 & 7000 Series DISHWASHERS
4.10.10.2 Suspend Mode
Models 6600,6605 and 7000 have no suspend mode
indication
The suspend mode is intended to prevent water being
pushed under the door, due to rapid expansion of the ambient
temperature air inside a recently closed dishwasher cabinet,
when hot water is initially recirculated (sprayed) throughout
the cabinet. This is achieved by providing a delay, from when
the dishwasher door is closed until the recirculation (Wash)
pump is started, so that the air inside the cabinet can be
heated slowly by natural convection.
necessary when the water is significantly hotter than the
ambient air.
If the door switch contacts open after a program has been
started, while the water temperature as sensed by the door
thermistor is greater than 113ºF, then the Suspend Timer
shall be started once the dishwasher door is closed again.
The Suspend Timer shall not be affected by the dishwasher
being in a paused state. Suspend mode can not be overrid-
den in any way.
While the Suspend Timer is active, any output step combina-
tion that involves the Recirculation (Wash) pump shall be
suspended, until the Suspend Timer period expires. (This
includes test modes). For example: Fill & Wash, Wash, Wash
& Heat, Wash & Heat & Dispense, etc. steps will be sus-
pended. However: Fill, Heat-Dry, Drain, Fan, etc. steps will
not be suspended.
The Suspend Timer period shall be 90 seconds and shall only
count down when the door is closed, regardless of whether
the program is paused or not. The suspend time shall be
reset to 90 seconds if the door is opened again during
suspend mode.
Once the Suspend Timer has expired, (counted down from 90
seconds to zero), the program shall automatically continue,
unless in the paused mode, in which case it shall remain
paused until the program button or start button is pressed
again.
LED operation during Suspend
While in suspend mode with the door closed and the machine
paused, the SENSING LED shall be on and the selected
program LED is to flash at a rate of, 1 second on, 1 second
off.
While in suspend mode with the door closed and the program
not paused, the SENSING LED and the selected program
LED shall be on.
4.10.10.3 Buzzer silencing
This feature is not available on Rotary models 6600 and
6605.
The buzzer can be silenced by pressing START/CANCEL
and NORMAL WASH, (or POTS NORMAL on 6905), buttons
together. Subsequent pressing of both buttons together will
enable/silence the buzzer. When silencing the buzzer is not
to sound.
When enabling the buzzer a 0.5-second beep should be
heard.
This delay is only
The buzzer silencing feature will only affect normal customer
operation. It will not affect any of the test modes, or Special
functions.
4.10.10.4 Toggle Light Mode (7000 series only).
This feature is only available on 7000 series models.
The Toggle Light mode allows the Program and Option LEDs
to be observed while the door is closed, during normal
customer operation. This mode does not affect test modes,
as test modes do not turn off the LEDs when the door is
closed.
This feature is enabled by holding down the SMART DRY and
START/CANCEL buttons for 3 seconds or longer. After 3
seconds the buzzer will sound for 0.5 seconds to indicate that
the mode has been enabled.
This feature is disabled by holding down the SMART DRY
and START/CANCEL buttons for 3 seconds or longer. After 3
seconds the buzzer will sound for 0.5 seconds to indicate that
the mode has been disabled, (no LEDs will flash). Alterna-
tively this mode will be disabled when power is removed.
Note: Buzzer silencing mode has no effect when enabling
and disabling this mode
