You leading plumbing company wouldn't even know 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 lock. The door lock pulls the door securely to the primary body of your dishwasher and prevents water from leaking during a cycle. If your dishwashing machine doesn't start, it top plumbing contractors 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 dishwashing machine tub will be a metal or plastic prong. Close and latch the door. The prong will depress the door switch totally and the circuit will close allowing the dishwashing machine to start. Check the prong to make sure it's not loose or bent and it's effectively triggering the door switch.
It is essential to disconnect the dishwashing machine from its power source before trying any repair. You can unplug the dishwasher from the outlet, get rid of the fuse from your fuse box, or quality best plumbing company 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 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 common terminal (COM), normally closed terminal (NC) or an usually open terminal (NO). Switches with only 2 terminals will either have a COM and a NO, or a COM and an NC. Door switches with 3 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 may be essential to get rid of the inner panel of the door initially. You can do this by eliminating a couple of screws. The screws at the bottom of the door are for the hinges. You do not need to eliminate the entire door for this repair.
Once the inner panel is removed you may discover another smaller panel covering the back of the control panel held in location with screws or clips. By removing this panel you will gain access to the latch assembly real estate the door switch.
How to get rid of the switch
Carefully usage 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 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 hurry and break the switch's real estate you will end up needing to change more parts.
How to evaluate your door switch
Use an ohmmeter to check the switch for continuity. This test is for door switches with 3 terminals.
1. Set your ohmmeter to measure resistance at a scale of Rx1.
2. Touch the metal ideas of the test recommended best plumbing company leads together and zero your ohmmeter by changing the thumbwheel experienced plumber near me in the front of the meter until the needles checks out "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 needs to provide 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 until you hear a 'click'.
6. With the 'click' of the actuator, the meter needs to produce a resistance reading of absolutely no ohms. This indicates the circuit is closed and continuity exists. (You will only hear this click with a door switch with three terminals.)
7. Keep the meter lead that is touching the COM terminal in place, but move the other meter lead from the NO terminal to the NC terminal.
8. When the actuator is launched, you need to receive a resistance reading of no 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 2 leads should 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 should get a regular reading of infinity.
Any readings that differ from the tests above are indications of a faulty door switch that will need to be replaced.
Replace the old switch with a brand-new one, using the same procedure as described 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 dishwashing machine through a cycle to ensure it's working correctly.
