The on/off button on the dishwasher will not function if there is no electricity to it. In addition, check your home's fuse box to ensure that no fuses have blown, which would prohibit the on/off switch from turning on the dishwasher. If your dishwasher consistently blows fuses, you may need to purchase more robust fuses. You can also try using a non-contact voltage detector. This tool will tell you whether there is any voltage being sent to an appliance even if the circuit is not broken.
Here are five reasons why your dishwasher isn't operating properly. 1. Power supply issues: When there is a problem with the power source, the dishwasher may not operate at all. If your dishwasher isn't operating, look for any blown fuses or tripped circuit breakers. Check that the wiring to the house is not damaged and that there are no loose wires anywhere in the area of the dishwasher. If these tests come back good, then call an electrician so he can determine what's wrong with the power supply.
2. Leaking water pump: A leaking water pump will cause your dishwasher to drain itself completely empty every time it runs. This problem can be fixed by replacing the pump, which is a relatively easy repair.
3. Inoperative control board: The control board is the brain of your dishwasher; it determines how it functions and when it needs repairing. Components on this board fail naturally due to age and use, but sometimes it also happens because of malfunctioning of other components. For example, if the motor fails to turn off after washing is complete, it means that the control board is not functioning properly and you should call an electrician to fix it.
4. Open door/open lid sensors: These sensors detect whether the door or lid of the dishwasher is open and stop the machine from running if it is.
If your dishwasher won't start, the door latch or door latch switches may be faulty. If the door cannot be closed correctly to activate the door latch switches, or if the switches are faulty, the dishwasher controls will not get electricity, and the dishwasher will not start. To test the door latch switches, lift up on the handle of the dishwasher and open the door all the way. The door should close by itself when it is latched properly. If it does not, contact a local appliance repair shop for assistance.
Reset the Circuit Breaker on the Dishwasher
If there is no light in the control panel of your dishwasher, the first thing you should do is ensure that the machine is correctly connected to the power source in the wall. If it's correctly plugged in, you should test the outlet by plugging in another device. If it works, then the problem may be with the dishwasher itself. You can call the manufacturer for help.
If the outlet is OK but the dishwasher isn't lighting up, try turning off the gas supply valve at the street meter. This will cut off gas to the house until someone turns it back on. If the dishwasher remains un-lit after doing this, then the problem lies within the kitchen cavity and needs fixing by a professional.
Wait 2 minutes after pressing the "Start/Reset" pad to reset the dishwasher. If the problem persists, reset (reboot) the dishwasher by unplugging it from the home circuit breaker/fuse box for 30 seconds. Restore electricity, and the dishwasher should resume regular operation. It may be necessary to repeat this procedure multiple times before having success.
If the dishwasher isn't turning on, check the internal wiring. Remove the front panel of the dishwasher and unplug it from the power source. Examine the wiring to the timer and door switch, as well as the wiring from the door to the dishwasher's base. Replace any rusted or damaged wires. If those checks reveal no problems, then call a repair person to install a new circuit breaker for the dishwasher. The technician will want to make sure that the line is not too long and may ask you to shorten it so he/she can ensure there are no other obstacles preventing power from reaching the dishwasher.
If your dishwasher still won't turn on, look at the plug. If it's been in another room with hot water used, replace the fuse inside the wall plate. This should fix the problem.
If the dishwasher has an electrical problem but still turns on when you push the start button, open the door and check the program button. It should be in the off position. If not, press the button until it is.
Now try the cycle again. If the problem persists, contact a repair person.
If the dishwasher overheats, the thermal fuse cuts power to it. When the thermal fuse bursts, the dishwasher will not start. To see if the thermal fuse is faulty, use a multimeter to check for continuity. Replace the thermal fuse if it does not have continuity. This repair should be done by a qualified appliance technician.
