Make it Start with a Door Switch Dishwashing machine Repair

You wouldn't even understand your dishwasher had one till it isn't working. These little switches are tucked inside the control board of your dishwasher and most times belong of experienced Mornington plumber the door latch. The door lock pulls the door securely to the main body of your dishwasher and avoids water from dripping during a cycle. If your dishwashing machine does not begin, it might be due to a malfunctioning door switch.

How the door switch 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 begin. Examine the prong to ensure it's not loose or bent and it's correctly activating the door switch.

It is very important to disconnect the dishwasher from its power source before attempting any repair. You can disconnect the dishwasher from the outlet, remove 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 looks like and where it's located

Typically a dishwashing machine 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 two terminals and some have three.

The terminals can be a typical terminal (COM), generally closed terminal (NC) or a generally open terminal (NO). Switches with only two 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 dishwasher's door switch will lag the control panel on the front of the system. It may be necessary to eliminate the inner panel of the door initially. You can do this by removing 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 might discover another smaller sized panel covering the back of the control board held in place with screws or clips. By eliminating this panel you will get to the lock assembly real estate the door switch.

How to get emergency plumber Langwarrin rid of the switch

Carefully usage needle nose pliers to pull the wires leading from the harness off the terminals. For door changes that have a locking clip, depress the lever as you gently pull the harness away from the terminal.

Take your time while getting rid of switches best plumber Langwarrin that belong of the lock assembly or that have a bracket. If you hurry and break the switch's housing you will end up needing to change more parts.

How to test your door switch

Use an ohmmeter to check the switch for continuity. 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 tips 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 result in the NO terminal. Do not push in on the actuator.

4. Your meter must 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 until you hear a 'click'.

6. With the 'click' of the actuator, the meter should produce a resistance reading of absolutely no ohms. This suggests the circuit is closed and continuity is present. (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 released, you must receive a resistance reading of zero ohms.

9. Now set your ohmmeter to its highest resistance scale and touch one meter cause the NO terminal and the other meter cause the NC terminal.

10. The resistance reading in between these two leads need to be infinite.

11. Finally take a resistance reading from both the NC terminal and the NO terminal to any metal licensed plumber Dandenong mounting hardware that is a part of the switch assembly. You need to receive a regular reading of infinity.

Any readings that differ from the tests above are signs of a faulty door switch that will need to be replaced.

Replace the old switch with a new one, using the very same process as discussed above. Reassemble the inner door panel and reconnect your dishwasher to its power supply. Do not 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.
