Make it Start with a Door Switch Dishwashing machine Repair
You wouldn't even understand your dishwasher had one till 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 lock pulls the door firmly to the main body of your dishwasher and prevents water from leaking during a cycle. If your dishwashing machine does not begin, it could be due to a faulty door switch.
How the door switch works
When the dishwasher 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 enabling the dishwashing machine to start. Check the prong to make certain it's not loose or bent and it's appropriately activating the door switch.
It is essential to detach the dishwashing machine from its power source before attempting any repair work. You can disconnect the dishwasher from the outlet, get rid of the fuse from your fuse box, or flick the breaker turn on your circuit panel. This will avoid you from getting an electrical shock.
What a door switch appears 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 two terminals and some have three.
The terminals can be a common terminal (COM), typically closed terminal (NC) or a typically open terminal (NO). Switches 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 might be necessary to remove 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 need to get rid of the whole door for this repair.
Once the inner panel is removed you may discover another smaller panel covering the back of the control board kept in location with screws or clips. By eliminating this panel you will get to the latch assembly real estate the door switch.
How to get rid of 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 far from the terminal.
Take your time while getting rid of switches that belong of the lock assembly or that have a bracket. If you rush and break the switch's real estate you will wind up having to change more parts.
How to evaluate your door switch
Use an ohmmeter to test the switch for connection. This test is for door changes with three 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 changing the thumbwheel in the front of the meter till the needles checks out "0" on learn about this https://canvas.curtin.edu.au/eportfolios/998/home/recognizing-the-signs-of-a-plumbing-problem the scale.
3. Touch one meter cause the COM terminal and the other result in the NO terminal. Do not push in on the actuator.
4. Your meter needs to provide a reading of infinity, implying the circuit is open, and there is no continuity.
5. Without moving the meter's leads, read this http://edition.cnn.com/search/?text=read this press down on the actuator till you hear a 'click'.
6. With the 'click' of the actuator, the meter ought to produce a resistance reading of zero 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 need to get a resistance reading of zero ohms.
9. Now set your ohmmeter to its highest resistance scale and touch one meter lead to the NO terminal and the other meter cause the NC terminal.
10. The resistance reading between these 2 leads must be infinite.
11. Finally take a resistance reading from both the NC terminal and the NO terminal to any metal mounting hardware that is a part of the switch assembly. You must get a typical reading of infinity.
Any readings that vary from the tests above are signs of a faulty door switch that will require to be replaced.
Replace the old switch with a new one, using the exact same process as described 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 dishwasher through a cycle to make sure it's working correctly.
