Make it Start with a Door Switch Dishwashing machine Repair

How the door switch works
When the dishwashing machine door is open, the switch is off. Inside your dishwashing machine tub will be a metal or plastic prong. Close and latch the door. The prong will depress the door switch completely and the circuit will close permitting the dishwasher to begin. Inspect the prong to make certain it's not loose or bent and it's appropriately triggering the door switch.
It is necessary to detach the dishwashing machine from its source of power before attempting any repair work. You can disconnect the dishwashing machine from the outlet, eliminate the fuse from your circuit box, or flick the breaker switch on your circuit panel. This will prevent you from getting an electrical shock.
What a door switch looks like and where it's located
Typically a dishwasher door switch is an inch long. It can be black or red and has metal prongs called terminals extending from the body. Some door switches have 2 terminals and some have three.
The terminals can be a typical terminal (COM), typically closed terminal (NC) or a generally open terminal (NO). Changes with only 2 terminals will either have a COM and a NO, or a COM and an NC. Door switches with three terminals have COM, NC, and a NO.
Your dishwasher's door switch will be behind the control board on the front of the unit. It may be needed to get rid of the inner panel of the door first. You can do this by eliminating a few screws. The screws at the bottom of the door are for the hinges. You do not require to eliminate the whole door for this repair.
Once the inner panel is removed you may find another smaller sized panel covering the back of the control board held in location with screws or clips. By eliminating this panel you will access to the latch assembly real estate the door switch.
How to fixitrightplumbing.com get rid of the switch
Carefully usage needle nose pliers to pull the wires leading from the harness off the terminals. For door changes that have a locking clip, depress the lever as you carefully pull the harness far from the terminal.
Take your time while eliminating switches that belong of the latch assembly or that have a bracket. If you hurry and break the switch's housing you will end up needing to change more parts.

Use an ohmmeter to test the switch for continuity. This test is for door changes with 3 terminals.
1. Set your ohmmeter to measure resistance at a scale of Rx1.
2. Touch the metal tips of the test leads together and zero your ohmmeter by changing the thumbwheel in the front of the meter until the needles checks out "0" on the scale.

4. Your meter needs to give a reading of infinity, indicating the circuit is open, and there is no continuity.
5. Without moving the meter's leads, press down on the actuator till you hear a 'click'.
6. With the 'click' of the actuator, the meter should produce a resistance reading of no ohms. This indicates the circuit is closed and connection is present. (You will only hear this click with a door switch with three terminals.)
7. Keep the meter lead that is touching the COM terminal in place, but move the other meter lead from the NO terminal to the NC terminal.
8. When the actuator is launched, you ought to receive a resistance www.fixitrightplumbing.com reading of absolutely no ohms.
9. Now set your ohmmeter to its highest resistance scale and touch one meter lead to the NO terminal and the other meter result in the NC terminal.
10. The resistance reading in between these two leads should be infinite.
11. Finally take a resistance reading from both the NC terminal and the NO terminal to any metal mounting hardware that belongs of the switch assembly. You must receive a typical reading of infinity.
Any readings that vary from the tests above are signs of a malfunctioning door switch that will need to be replaced.
Replace the old switch with a new one, utilizing the same process as explained above. Reassemble the inner door panel and reconnect your dishwashing machine to its power supply. Don't forget to replace your fuse or turn the breaker switch back on. Run your dishwashing machine through a cycle to make sure it's working effectively.
