Make this test and fix it. Merry Christmas. 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 the 120 volts in p. 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 power comes into the main power box and usually runs to the door switch next before entering the main control module. Replace the door switch if is faulty, use the Multimeter
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 main control modul l/timer 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 the motor is having power 120v
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.
