Make it Start with a Door Change Dishwashing machine Repair
You wouldn't even know your dishwashing machine had one until it isn't working. These little switches are tucked inside the control board of your dishwasher and most times belong of the door latch. The door latch pulls the door firmly to the main body of your dishwashing machine and avoids water from dripping throughout a cycle. If your dishwasher does not start, it might be due to a malfunctioning 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 latch the door. The prong will depress the door switch entirely 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 appropriately triggering the door switch.
It is essential to detach the dishwasher from its source of power before trying any repair work. You can unplug the dishwasher from the outlet, remove the fuse from your circuit box, or flick the breaker switch on your circuit panel. This will avoid cloggeed drain vic 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 actually metal prongs called terminals protruding from the body. Some door switches have 2 terminals and some have three.
The terminals can be a common terminal (COM), usually closed terminal (NC) or a typically 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 three terminals have COM, NC, and a NO.
Your dishwashing machine's door switch will lag the control board on the front of the unit. It might be essential to remove the inner panel of the door first. You can do this by eliminating a couple of screws. The screws at the bottom of the door are for the hinges. signs of a clogged drain You do not need to remove the entire door for this repair.
Once the inner panel is eliminated you may find another smaller panel covering the back of the control panel kept in location with screws or clips. By eliminating this panel you will gain access to the latch assembly housing 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 getting rid of 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 wind up needing to change more parts.
How to check your door switch
Use an ohmmeter to test the switch for continuity. This test is for door changes with 3 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 up 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 needs to give a reading of infinity, suggesting 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 means the circuit is closed and continuity is present. (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 location, 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 absolutely no ohms.
10. The resistance reading in between these 2 leads must be infinite.
11. Lastly take a resistance reading from both the NC terminal and the NO terminal to any metal mounting hardware that belongs of the switch assembly. You ought to receive a regular reading of infinity.
Any readings that vary from the tests above are indications of a faulty door switch that will require to be replaced.
Replace the old switch with a brand-new one, utilizing the 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 dishwasher through a cycle to make sure it's working properly.
