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 plumber Canberra control board of your dishwashing machine and most times are a part of the door latch. The door latch pulls the door safely to the primary body of your dishwasher and prevents water from leaking during a cycle. If your dishwashing machine does not begin, it might be due to a defective 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 lock the door. The prong will depress the door switch totally and the circuit will close allowing the dishwasher to start. Inspect the prong to make certain it's not loose or bent and it's effectively activating the door switch.
It is important to disconnect the dishwashing machine from its source of power before trying any repair. You can unplug the dishwasher from the outlet, eliminate the fuse from your fuse box, or flick the breaker turn on your circuit panel. This will avoid you from getting an electric 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 protruding from the body. Some door switches have two terminals and some have three.
The terminals can be a typical terminal (COM), normally closed terminal (NC) or an usually open terminal (NO). Switches with just two terminals will either have a COM and a NO, or a COM and an NC. Door changes with 3 terminals have COM, NC, and a NO.
Your dishwasher's door switch will lag the control board Learn more on the front of the system. It may be essential to eliminate the inner panel of the door first. You can do this by removing a couple of screws. The screws at the bottom of the door are for the hinges. You do not require to remove the whole door for this repair.
Once the inner panel is eliminated you may discover another smaller panel covering the back of the control panel kept in place with screws or clips. By eliminating this panel you will access to the lock assembly real estate the door switch.
How to eliminate the switch
Carefully usage 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 eliminating switches that belong of the lock assembly or that have a bracket. If you rush and break the switch's housing you will end up having to change more parts.
How to test your door switch
Use an ohmmeter to evaluate the switch for continuity. This test is for door changes with 3 terminals.
1. Set your ohmmeter to determine resistance at a scale of Rx1.
2. Touch the metal tips 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 lead to the COM terminal and the other lead to the NO terminal. Do not push in on the actuator.
4. Your meter needs to give a reading of infinity, implying 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 needs to produce a resistance reading of no ohms. This means the circuit is closed and continuity is present. (You will just hear this click with a door switch with 3 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 released, you should get a resistance reading of no ohms.
9. Now set your ohmmeter to its highest resistance scale and touch one meter cause the NO terminal and the other meter lead to the NC terminal.
10. The resistance reading in between these two leads need to be infinite.
11. Finally take a resistance reading from both the NC terminal and the NO terminal to any metal installing hardware that is a part of the switch assembly. You must get a regular reading of infinity.
Replace the old switch with a brand-new one, using the same process as explained above. Reassemble the inner door panel and reconnect your dishwasher 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 ensure it's working correctly.
