Hello ...
I tried to look up your model numbers here (usa)...
with no success... (Kenmore 13742 / 13744 / 13749)
I rarely (ever) suggest owners go direct to Sears...
but this would seem to be.. appropriate...
(I my opinion they are rude & pushy to sell parts
(good news ... here... their guaranteed fit/fix)).
Before doing so...
Check your water, drain & power at the appliance.
With the breaker turned of...
open the appliance cord JUNCTION BOX and assure the
wiring devices (usually "wire nuts") are still tight and secure.
Finding nothing... you are at the UNHAPPY JUNCTURE
where you need to use SEARS PARTS DIRECT...

you'll need to reset the control board. To do this press "high temp wash, heated dry, high temp wash, heated dry, high temp wash, heated dry, high temp wash".
All the lights will turn solid at which point you can press the cancel button to reset the control board.
**NOTE** if you don't have a "heated dry" button on your console, use the "air dry" or "energy saver dry" button instead.
SEE THE Causes and Fix it: God bless you
Power Supply
The main power supply is the first thing to check. Also remove the toe
kick and the cover on the power box and check the connections. Also check for 120 volt at the power box.
Hi - Limit Fuse
This will fail if your dishwasher overheats and occassionally with power
surges. This is easy to check, inexpensive and a quick fix. Just check
the terminals for continuity ( remember always remove one wire) if you
have none replace the hi limit fuse.
Door Switch
This is the second place to look. Again an inexpensive easy fix. The following video will walk you thru checking the door switch. The power comes into the main power box and usually runs to the door switch next before entering the main control module.
Main Control Module / Timer
The main control module or mechanical timer controls all the functions
of the dishwasher. To check this you will need to find the 2 leads that
supply the power to the control. They will be marked on the wiring
diagram. They usually come from the hi - limit fuse or the door switch.
When the door is latched you should have 120 volts entering the main
control. If you do not the problem is not the control. If you do have
power entering the control but none of the functions work properly or it
does not respond at all you will need to replace the control module,
this is easy to replace but not very inexpensive to purchase. Consider
the age and overall condition when purchasing this part.
Motor
The motor may have failed. If the control illuminates on electronic
versions the problem may be the motor. To check the motor refer to the
tech sheet located behind the console cover on most models, this will
sometimes have the ohm reading of the motor. Also check each lead to the
metal housing of the motor to check for shorts in the motor. If you do
not have the ohm reading specicifications, check for continuity if none replace the motor. Make sure the motor is recieving power.
Float Switch
If the float switch has failed or is stuck the dishwasher control may
not respond. The float switch is easy to check and replace. We have video and tutorials that cover several styles.
see the diagram attached:1) test the switch door for defective or open, if there are wrong the relais will not close and NOT start the motor.2) Timer test, 3) c.breaker from you home or blown fuse 4) wires defective loose, burn, or break
