Make it Start with a Door Switch Dishwasher Repair
You wouldn't 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 latch pulls the door safely to the primary body of your dishwashing machine and avoids water from dripping throughout a cycle. If your dishwashing machine doesn't start, it could be due to a malfunctioning door switch.
How the door switch Mount Martha plumbing services 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 permitting the dishwashing machine to start. Check the prong to ensure it's not loose or bent and it's correctly activating the door switch.
It is important to disconnect the dishwasher from its source of power before trying any repair work. You can unplug the dishwashing machine from the outlet, eliminate the fuse from your fuse box, or flick the breaker switch on your circuit panel. This will prevent 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 extending from the body. Some door switches have two terminals and some have three.
The terminals can be a common terminal (COM), typically closed terminal (NC) or a typically open terminal (NO). Changes with just 2 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 dishwasher's door switch will lag the control board on the front of the unit. It might be required to get rid of the inner panel of the door first. 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 get rid of the whole door for this repair.
Once the inner panel is eliminated you might discover another smaller panel covering the back of the control board kept in location with screws or clips. By eliminating this panel you will access to the latch assembly real estate the door switch.
How to remove 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 getting rid of switches that belong of the lock assembly or that have a bracket. If you hurry and break the switch's housing you will wind up needing to change more parts.
How to check your door switch
Use an ohmmeter to test the switch for connection. This test is for door switches 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 changing the thumbwheel in the front of the meter until the needles reads "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 needs to produce a resistance reading of zero ohms. This implies the circuit is closed and connection 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, but move the other meter lead from the NO terminal to the NC terminal.
8. When the actuator is released, you need to receive a resistance reading of absolutely 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 ought to be infinite.
11. Finally take licensed plumber in Baxter 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 qualified plumber near you from the tests above are signs of a defective door switch that will require to be replaced.
Replace the old switch with a new one, using the exact same process as discussed 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 sure it's working effectively.
