Make it Start with a Door Switch Dishwashing machine Repair
You wouldn't even understand your dishwashing machine had one up until it isn't working. These little switches are tucked inside the control panel of your dishwasher and most times belong of the door lock. The door latch pulls the simple toilet fixes door securely to the primary body of your dishwashing machine and prevents water from dripping during a cycle. If your dishwashing machine doesn't begin, 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 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 permitting the dishwashing machine to begin. Inspect the prong to make certain it's not loose or bent and it's properly activating the door switch.
It is essential to detach the dishwashing machine from its source of power before trying any repair work. You can unplug the dishwashing machine from the outlet, eliminate the fuse from your circuit 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 dishwashing machine 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), generally closed terminal (NC) or a normally 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 3 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 get rid of the inner panel of the door first. You can do this by getting rid of a few screws. The screws at the bottom of the door are for the hinges. You do not need to remove the entire door for this repair.
Once the inner panel is eliminated you may find another smaller sized panel covering the back of the control board kept in place with screws or clips. Preparing Pipes for Winter By eliminating this panel you will gain access to the latch assembly real estate the door switch.
How to remove the switch
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 housing you will end up needing to replace more parts.
How to check your door switch
Use an ohmmeter to evaluate 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 suggestions 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 cause 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, implying 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 must produce a resistance reading of zero 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 location, but move the other meter lead from the NO terminal to the NC terminal.
8. When the actuator is launched, you need to get a resistance reading of no ohms.
9. Now set your ohmmeter to its highest resistance scale and touch one meter cause the NO terminal and the other meter result in the NC terminal.
10. The resistance reading 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 installing hardware that is a part of the switch assembly. You must receive a typical reading of infinity.
Any readings that differ from the tests above are signs of a faulty door switch that will require to be replaced.
Replace the old switch with a new one, using the same process as discussed above. Reassemble the inner door panel and reconnect your dishwasher 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 appropriately.
