Make it Start with a Door Change Dishwasher Repair
You would not even understand your dishwasher had one until it isn't working. These little switches are tucked inside the control board of your dishwashing machine and most times are a part of the door latch. The door lock pulls the door safely to the main body of your dishwasher and prevents water from leaking throughout a cycle. If your dishwashing machine doesn't start, it could be due to a faulty door switch.
How the door switch works
When the dishwashing machine 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 allowing the dishwashing machine to start. Inspect the prong to make sure it's not loose or bent and it's correctly activating the door switch.
It is very important to detach the dishwashing machine from its source of power before attempting any repair. You can unplug 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 electric shock.
What a door switch appears 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 normally open terminal (NO). Changes with only two terminals will either have a COM and a NO, or local best plumbing company a COM and an NC. Door switches with three terminals have COM, NC, and a NO.
Your dishwasher's door switch will be behind the control panel on the front of the system. It might be necessary to eliminate 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 need to eliminate the whole door for this repair.
Once the inner panel is eliminated you may find another smaller sized panel covering the back of the control panel held in location with screws or clips. By eliminating this panel you will gain access to the lock assembly real estate the door switch.
How to remove 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 getting rid of switches that are a part 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 evaluate your door switch
Use an ohmmeter to test the switch for continuity. 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 adjusting the thumbwheel in the front of the meter until the needles reads "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 must give a reading of infinity, indicating 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 should 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 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 launched, you must get a resistance reading of zero ohms.
9. Now set your ohmmeter to its highest resistance scale and touch one meter result in the NO terminal and the other meter result in the NC terminal.
10. The resistance reading between these two leads ought to be infinite.
11. Finally 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 must get a regular 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 new one, using the same procedure as described above. Reassemble the inner door panel and reconnect your dishwashing experienced plumbing company machine to its power supply. Do not forget to replace your fuse or turn the breaker switch back on. Run your dishwasher through a cycle to ensure it's working correctly.
