You wouldn't even know your dishwasher had one up until it isn't working. These little switches are tucked inside the control panel of your dishwasher and most times are a part of the door latch. The door latch pulls the door securely to the main 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 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 latch the door. The prong will depress the door switch completely and the circuit will close permitting the dishwashing machine to begin. Check the prong to make certain it's not loose or bent and it's effectively activating the Preparing Pipes for Winter door switch.
It is very important to detach the dishwasher from its source of power before attempting any repair. You can disconnect the dishwashing machine from the outlet, eliminate the fuse from your fuse box, or flick the breaker turn on your circuit panel. This will prevent you from getting an electrical shock.
What a door switch appears 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), usually closed terminal (NC) or a typically open terminal (NO). Switches with only 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 be behind the control panel on the front of the unit. It might be needed to eliminate the inner panel of the door initially. You can do this by eliminating a few screws. The screws at the bottom of the door are for the hinges. You do not need to remove the whole door for this repair.
Once the inner panel is eliminated you might discover another smaller sized panel covering the back of the control board held in location with screws or clips. By removing this panel you will gain access to the lock assembly housing essential plumbing improvements 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 are a part of the latch assembly or that have a bracket. If you rush and break the switch's real estate you will wind up needing to change more parts.
How to evaluate your door switch
Use an ohmmeter to test 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 suggestions of the test leads together and zero your ohmmeter by changing the thumbwheel in the front of the meter till the needles reads "0" on the scale.
3. Touch one meter cause the COM terminal and the other cause the NO terminal. Do not press in on the actuator.
4. Your meter ought to offer 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 zero ohms. This means the circuit is closed and continuity 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 zero ohms.
10. The resistance reading in between these 2 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 is a part of the switch assembly. You ought to receive a typical reading of infinity.
Any readings that differ from the tests above are signs of a malfunctioning door switch that will need to be replaced.
Replace the old switch with a brand-new one, using the very same process as described above. Reassemble the inner door panel and reconnect your dishwashing machine 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 make certain it's working properly.
