Make it Start with a Door Switch Dishwashing machine Repair
You wouldn't even understand 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 belong of the door latch. The door latch pulls the door safely to the main body of your dishwashing machine and avoids water from leaking throughout a cycle. If your dishwasher does not begin, it could be due to a defective door switch.
How the door switch works
When the dishwasher door is open, the switch is off. Inside your dishwasher 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 start. Check the prong to make sure it's not loose or bent and it's properly triggering the door switch.
It is very important to detach the dishwashing machine from its source of power before trying any repair. You can unplug the dishwashing machine from the outlet, remove 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 looks like and where it's located
Typically a dishwasher door switch is an inch long. It can be black or red and has actually metal prongs called terminals protruding from the body. Some door switches have two terminals and some have three.
The terminals can be a common terminal (COM), usually closed terminal (NC) or a generally open terminal (NO). Changes with just 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 dishwashing machine's door switch will lag the control panel on the front of the system. It may be necessary to remove the inner panel of the door initially. You can do this by getting rid of a couple of 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 eliminated you may discover another smaller panel covering the back of the control panel held in place with screws or clips. By removing this panel you will gain access to the lock 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 gently 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 real estate you will wind up needing to change more parts.
How to test your door switch
Use an ohmmeter to check the switch for connection. This test is for door switches 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 result in the COM terminal and the other cause the NO terminal. Do not press in on the actuator.
4. Your meter should give a reading of infinity, meaning the circuit is open, and there is 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 ought to produce a resistance reading of no ohms. This indicates the circuit is closed and connection exists. (You will only hear this click with a door switch with 3 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 released, you should receive a resistance reading of no 24/7 plumber in Cranbourne 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 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 mounting hardware that belongs of the switch assembly. You need to receive a normal reading of infinity.
Any readings that differ from the tests above are signs of a faulty door switch that will need to be replaced.
Replace the old switch with a brand-new one, utilizing the same process as discussed above. Reassemble the inner door panel and reconnect your dishwasher to its power supply. Don't forget to change your fuse or turn the breaker switch back on. Run your dishwasher through a cycle to make sure it's working appropriately.
