Make it Start with a Door Switch Dishwasher Repair
You would not even understand your dishwashing machine had one till it isn't working. These little switches are tucked inside the control panel of your dishwasher and most times belong of the door lock. The door latch pulls the door safely to the primary body of your dishwashing machine and prevents water from dripping throughout a cycle. If your dishwashing machine does not begin, it might 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 lock the door. The prong will depress the door switch totally and the circuit will close allowing the dishwashing machine to begin. Examine the prong to make sure it's not loose or bent and it's correctly triggering the door switch.
It is essential to disconnect the dishwashing machine from its power source before attempting any repair. You can disconnect the dishwashing machine from the outlet, get rid of the fuse from your circuit box, or flick the breaker switch on your circuit panel. This will prevent you from getting an electric shock.
What a door switch looks like and where it's located
Typically a dishwashing machine 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 typical terminal (COM), generally closed terminal (NC) or a typically 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 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 system. It might be necessary to remove the inner panel of the door first. You can do this by removing a few 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 removed you may find another smaller sized panel covering the back of the control board held in place with screws or clips. By eliminating this panel you will gain 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 changes 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 hurry and break the switch's real estate you will wind up having to change more parts.
How to check your door switch
Use an ohmmeter to test the switch for connection. This test is for door switches with three 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 up until the needles checks out "0" on the scale.
3. Touch one meter lead to the COM terminal and the other cause the NO terminal. Do not press in on the actuator.
4. Your meter ought to provide a reading of infinity, meaning the circuit is open, and there is https://batchgeo.com/map/1034517479935f98b370bfd2757eb140 no continuity.
5. Without moving the meter's leads, press down on the actuator up until you hear a 'click'.
6. With the 'click' of the actuator, the meter needs to produce a resistance reading of zero ohms. This suggests the circuit is closed and continuity exists. (You will just hear this click with a door switch with three terminals.)
7. Keep the meter lead that is touching the COM terminal in place, however move the other meter lead from the NO terminal to the NC terminal.
8. When the actuator is launched, you must get a resistance reading of no ohms.
9. Now set your ohmmeter to its greatest resistance scale and touch one meter cause the NO terminal and the other meter result in the NC terminal.
10. The resistance reading in between these two leads must 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 receive a regular 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, utilizing the same procedure as discussed above. Reassemble the inner door panel and reconnect your dishwashing machine to its power supply. Don't 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.
