Make it Start with a Door Switch Dishwashing machine Repair

You would not even know your dishwasher had one till it isn't working. These little switches are tucked inside the control panel of your dishwashing machine and most times belong of the door lock. The door latch pulls the door safely to the main body of your dishwasher and prevents water from leaking 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 dishwashing machine 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 enabling the dishwasher to start. Check the prong to make sure it's not loose or bent and it's effectively activating the door switch.

It is essential to disconnect the dishwashing machine from its source of power before trying any repair. You can unplug the dishwasher from the outlet, eliminate the fuse from your fuse box, or flick the breaker switch on your circuit panel. This will avoid you from getting an electrical 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 2 terminals and some have three.

The terminals can be a typical terminal (COM), normally closed terminal (NC) or an usually 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 may be necessary to remove the inner panel of the door first. You can do this by removing a couple of screws. The screws at the bottom of the door are for the hinges. You do not require to remove the whole door for this repair.

Once the inner panel is eliminated you may find another smaller panel covering the back of Somerville plumbing company the control panel held in place with screws or clips. By eliminating this panel you will gain access to the lock assembly real estate the door switch.

How to get rid of the switch

Carefully use 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 removing switches that are a part of the latch assembly or that have a bracket. If you rush and break the switch's housing you will end up needing to replace more parts.

How to test your door switch

Use an ohmmeter to evaluate the switch for continuity. This test is for door changes with three 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 changing the thumbwheel in the front of the meter till the needles checks out "0" on the scale.

3. Touch one meter result in the COM terminal and the other lead to the NO terminal. Do not press in on the actuator.

4. Your meter ought to provide 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 till you hear a 'click'.

6. With the 'click' of the actuator, the meter must produce a resistance reading of absolutely no ohms. This implies 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 place, however move the other meter lead from the NO terminal to the NC terminal.

8. When the actuator is launched, you must receive a resistance reading of zero ohms.

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

10. The resistance reading in between these 2 leads ought to be infinite.

11. Lastly take a resistance reading from both the NC terminal and the NO terminal to any metal installing hardware that belongs of the switch assembly. You should receive a regular 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 brand-new one, utilizing the same process as described above. Reassemble the inner door panel and reconnect your dishwashing machine 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 ensure it's working properly.
