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 board of your dishwashing machine and most times belong of the door lock. The door latch pulls the door firmly to the primary body of your dishwasher and prevents water from leaking throughout 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 completely and the circuit will close permitting the dishwashing machine to begin. Inspect the prong to make sure it's not loose or bent and it's correctly activating the door https://myportal.utt.edu.tt/ICS/icsfs/Important-Plumbing-Maintenance-Tips.html?target=91013b8d-b4cf-4ebf-8873-85c67b9eedd1 switch.

It is essential to disconnect the dishwasher from its power source before trying any repair work. You can disconnect the dishwashing machine from the outlet, remove 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 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 common terminal (COM), usually closed terminal (NC) or a generally open terminal (NO). Changes 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 lag the control board on the front of the system. It might be needed to get rid of the inner panel of the door initially. 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 need to get rid of the entire door for this repair.

Once the inner panel is removed you may find another smaller panel covering the back of the control panel held in location with screws or clips. By removing 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 away from the terminal.

Take your time while removing switches that are a part of the latch assembly or that have a bracket. If you hurry and break the switch's housing you will end up having to replace more parts.

How to evaluate your door switch

Use an ohmmeter to test the switch for continuity. 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 ideas of the test leads together and zero your ohmmeter by adjusting the thumbwheel in the front of the meter till the needles reads "0" on the scale.

3. Touch one meter result in the COM terminal and the other result in the NO terminal. Do not press in on the actuator.

4. Your meter needs to provide 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 till you hear a 'click'.

6. With the 'click' of the actuator, the meter ought to produce a resistance reading of no 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 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 greatest resistance scale and touch one meter lead to the NO terminal and the other meter result in the NC terminal.

10. The resistance reading between these 2 leads need to be infinite.

11. Lastly 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 need to get a normal reading of infinity.

Any readings that vary 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 exact same process as described 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 dishwasher through a cycle to ensure it's working appropriately.
