Make it Start with a Door Switch Dishwasher Repair

You would not even know your dishwasher had one up 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 lock pulls the door firmly to the main body of your dishwashing machine and avoids water from dripping during a cycle. If your dishwashing machine does not start, it might be due to a defective door switch.

How the door switch works

When the dishwasher door is open, the switch is off. Inside your dishwashing machine tub will be a metal or plastic prong. Close and lock the door. The prong will depress the door switch completely and the circuit will close allowing the dishwashing machine to begin. Inspect the prong to ensure it's not loose or bent and it's effectively triggering the door switch.

It is important to disconnect the dishwasher from its source of power before attempting any repair work. You can unplug the dishwasher 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 extending from the body. Some door switches have two terminals and some have three.

The terminals can be a typical terminal (COM), usually closed terminal (NC) or a normally open terminal (NO). Changes with only two 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 Mount Martha plumbing company NO.

Your dishwasher's door switch will be behind the control panel on the front of the system. It may be necessary to eliminate the inner panel of the door first. You can do this by getting rid of a couple of 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 removed you might discover another smaller panel covering the back of the control board kept in place with screws or clips. By removing this panel you will get 24/7 emergency plumber to the lock 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 away 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 wind up needing to replace more parts.

How to check your door switch

Use an ohmmeter to test the switch for connection. This test is for door switches with 3 terminals.

1. Set your ohmmeter to determine 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 up until the needles checks out "0" on the scale.

3. Touch one meter cause the COM terminal and the other result in the NO terminal. Do not push in on the actuator.

4. Your meter should give a reading of infinity, Baxter local plumbing 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 ought to produce a resistance reading of zero ohms. This implies the circuit is closed and connection 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 need to get a resistance reading of no ohms.

9. Now set your ohmmeter to its highest resistance scale and touch one meter lead to the NO terminal and the other meter top rated plumber Mornington result in the NC terminal.

10. The resistance reading between these 2 leads must be infinite.

11. Finally 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 get a typical reading of infinity.

Any readings that differ 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 same process as explained above. Reassemble the inner door panel and reconnect your dishwasher to its power supply. Do not forget to change your fuse or turn the breaker switch back on. Run your dishwasher through a cycle to make sure it's working properly.
