Make it Start with a Door Change Dishwashing machine Repair
You would not even know your dishwashing machine had one up until it isn't working. These little switches are tucked inside the control panel of your dishwashing machine and most times are a part of the door latch. The door latch pulls the door securely to the primary body of your dishwashing machine and avoids water from leaking throughout a cycle. If your dishwashing machine does not start, it could be due to a malfunctioning door switch.
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 lock the door. The prong will depress the door switch totally and the circuit will close enabling the dishwashing machine to begin. Inspect the prong to ensure it's not loose or bent and it's correctly activating the door switch.
It is essential to disconnect the dishwasher from its source of power before trying any repair. You can unplug the dishwasher from the outlet, get rid of the fuse from your fuse box, or flick the breaker switch on your circuit panel. This will avoid 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 common terminal (COM), normally closed terminal (NC) or an usually open terminal (NO). Changes with only 2 terminals will either have a COM and a NO, or a COM and an NC. Door changes with three terminals have COM, NC, and a NO.
Your dishwashing machine's door switch will be behind the control board on the front of the unit. It may be necessary to get rid of the inner panel of the door initially. 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 get rid of the whole door for this repair.
Once the inner panel is removed you may discover another smaller sized panel covering the back of the control board kept in place with screws or clips. By removing this panel you will access to the latch assembly housing the door switch.
How to eliminate the switch
Carefully use needle nose pliers to pull the wires leading from the harness off the terminals. For door switches that have a locking clip, depress the lever as you carefully pull the harness away from the terminal.
Take your time while removing switches that belong of the latch assembly or that have a bracket. If you rush and break the switch's housing you will end up needing to change more parts.
How to test your door switch
Use an ohmmeter to evaluate the switch for connection. 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 pointers of the test leads together and zero your ohmmeter by adjusting the thumbwheel in the front of the meter until the needles checks out "0" on the scale.
3. Touch one meter result in the COM terminal and the other cause the NO terminal. Do not push in on the actuator.
4. Your meter needs to offer 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 until you hear a 'click'.
6. With the 'click' of the actuator, the meter ought to 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 location, however 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 reading of absolutely no ohms.
9. Now set your ohmmeter to its greatest resistance scale and touch one meter result in the NO terminal and the other meter result in the NC terminal.
10. The resistance reading between these two leads ought to be infinite.
11. Finally take a resistance reading from both the NC terminal and the NO terminal to any metal installing hardware that belongs of the switch assembly. You must receive a regular reading of infinity.
Any readings that vary from the tests above are indications of a malfunctioning door switch that will need to be replaced.
Replace the old switch https://moodle.nccommunitycolleges.edu/tag/index.php?tc=1&tag=napping%20%3A-%29 with a new one, using the exact same procedure as described above. Reassemble the inner door panel and reconnect your dishwasher to its power supply. Do not forget to change your fuse or turn the breaker switch back on. Run your dishwashing machine through a cycle to ensure it's working appropriately.
