TIMERS
All KDC, KDI, KDP
&
KDS dishwashers have
the timers located behind the control panel (3 ,
Fig. II).
Timers are sometimes needlessly replaced, when
another component is at fault, due to incorrect
diagnosis. Thoroughly check timer before making
replacement. If, after making a timer replacement
the problem was not corrected, remove this
replacement and reuse the original timer.
If a timer operated component is inoperative, first
check to make sure voltage is reaching component.
For this check use a test lamp across component
contacts at the time it should be energized.
If voftage is reaching the inoperative component at
the correct time, the component should then be
checked mechanically and electrically. If voltage is
not reaching the component, the continuity
between this component and the timer must be
checked. If continuity exists, the timer should
then be checked and replaced, as necessary .
TIMER (KDS-18, "SUPERBA") (Fig. 14)
KDS-18 timers operate on a unique principle:
although each interval is of 90-second duration,
the angular movement of each interval will vary in
a predetermined pattern. In addition, they utilize
multiple connector plugs to connect the dish-
washer electrical harness with the timer.
