H1How to Troubleshoot a GE Dishwasher That Won’t StartH1
Is your GE dishwasher refusing to start? A non-starting dishwasher can disrupt your kitchen routine and leave you with a pile of dirty dishes. Before calling a repair technician, there are several troubleshooting steps you can take to diagnose and potentially fix the problem yourself. This comprehensive guide will walk you through common reasons why your GE dishwasher won’t start, providing detailed instructions and solutions to get it back up and running. Remember to always disconnect the power supply before attempting any repairs.
H2Safety First: Disconnect the PowerH2
Before you begin any troubleshooting, your safety is paramount. Always disconnect the power to your dishwasher to prevent electric shock. Here’s how:
* **Locate the Breaker:** Find the circuit breaker in your electrical panel that controls the dishwasher. It’s usually labeled “Dishwasher” or “Kitchen Appliances.” If you’re unsure, you can test breakers by switching them off one by one until the dishwasher’s control panel lights go off.
* **Turn Off the Breaker:** Flip the breaker switch to the “Off” position.
* **Confirm Power is Off:** Double-check that the dishwasher’s control panel is completely dark and unresponsive. You can also try briefly pressing the start button to confirm there is no power.
Alternatively, if the dishwasher is plugged into an outlet under the sink, you can unplug it directly. However, using the breaker is the preferred and safest method.
H2Common Reasons Why Your GE Dishwasher Won’t StartH2
Several factors can prevent your GE dishwasher from starting. Here’s a breakdown of the most common culprits:
* **Power Issues:** The dishwasher isn’t receiving power.
* **Door Latch Problems:** The door isn’t properly latched, preventing the start cycle.
* **Control Lock is Activated:** The control lock feature is engaged, disabling the buttons.
* **Faulty Start/Cancel Button:** The start or cancel button is malfunctioning.
* **Thermal Fuse Blown:** The thermal fuse has blown due to overheating.
* **Motor Issues:** The motor is failing or has seized.
* **Control Board Problems:** The electronic control board is malfunctioning.
* **Float Switch Issues:** The float switch is stuck in the “up” position.
* **Timer Malfunction:** The timer is malfunctioning.
H2Troubleshooting Steps: A Detailed GuideH2
Follow these steps in order, systematically checking each potential cause:
H31. Verify Power SupplyH3
* **Check the Breaker:** Go back to your electrical panel and ensure the dishwasher’s breaker is still in the “On” position. Sometimes breakers can trip partially, so flip it fully to the “Off” position and then back to the “On” position.
* **Test the Outlet (If Applicable):** If the dishwasher is plugged into an outlet, use a multimeter or outlet tester to verify that the outlet is providing the correct voltage (usually 120V in North America). If the outlet is dead, check the circuit breaker again. You may also need to test other outlets on the same circuit to see if they’re working.
* **Inspect the Power Cord:** Check the dishwasher’s power cord for any signs of damage, such as cuts, fraying, or exposed wires. If you find any damage, the power cord needs to be replaced by a qualified electrician.
H32. Check the Door Latch and SwitchH3
The dishwasher won’t start if it doesn’t detect that the door is properly closed. The door latch mechanism engages a safety switch that signals to the control board that it’s safe to start the cycle.
* **Visually Inspect the Latch:** Examine the door latch for any visible damage, such as cracks, broken pieces, or misalignment. Make sure the latch is moving freely and engaging with the door frame properly.
* **Test the Latch Engagement:** Close the dishwasher door firmly. You should hear a distinct “click” as the latch engages. If the door doesn’t latch securely, try adjusting the latch mechanism or the door strike plate (the part of the door frame the latch catches). Loosen the screws holding the strike plate and move it slightly up or down to improve the alignment.
* **Test the Door Switch (Multimeter Required):** This step requires a multimeter and some electrical knowledge. *If you’re not comfortable working with electricity, it’s best to call a qualified appliance repair technician.*
* Locate the door switch. It’s usually located near the door latch mechanism, inside the dishwasher’s frame.
* Disconnect the wires connected to the door switch (remember their original positions for reassembly).
* Set your multimeter to the continuity setting (usually indicated by a diode symbol or a sound wave symbol).
* Place the multimeter probes on the switch terminals.
* With the door open (switch disengaged), the multimeter should show no continuity (open circuit).
* Manually depress the switch (simulate the door being closed). The multimeter should now show continuity (closed circuit).
* If the switch doesn’t change state when activated, it’s faulty and needs to be replaced.
H33. Disable Control Lock (Child Lock)H3
Many GE dishwashers have a control lock feature to prevent accidental operation, especially by children. If the control lock is engaged, the buttons will be disabled, and the dishwasher won’t start.
* **Locate the Control Lock Button:** The location of the control lock button varies depending on the model. It’s usually labeled with a lock symbol or the words “Control Lock,” “Child Lock,” or similar. Refer to your dishwasher’s user manual for the exact location.
* **Deactivate the Control Lock:** The method for deactivating the control lock also varies. Common methods include:
* Pressing and holding the control lock button for 3-5 seconds.
* Pressing and holding two specific buttons simultaneously (e.g., “Start” and “Heated Dry”) for 3-5 seconds. Again, consult your user manual.
* **Check for Indication:** Some models have an indicator light (often a lock symbol) that illuminates when the control lock is active. Once deactivated, the indicator light should turn off.
* **Test the Buttons:** After deactivating the control lock, try pressing other buttons to see if they respond. If the buttons are now working, the control lock was the issue.
H34. Test the Start/Cancel ButtonH3
A faulty start or cancel button can prevent the dishwasher from starting or responding to commands.
* **Check for Obvious Damage:** Visually inspect the start and cancel buttons for any physical damage, such as cracks, stickiness, or being stuck in a depressed position.
* **Try Pressing the Buttons Firmly:** Sometimes, a button might not be making proper contact. Try pressing the start button firmly and directly in the center. Do the same for the cancel button.
* **Test the Button with a Multimeter (If Possible):** This step is more difficult and may require disassembly of the control panel. *Proceed with caution and only if you’re comfortable with electronics repair.*
* Locate the start and cancel button terminals on the control board. Consult your dishwasher’s service manual or wiring diagram for their exact location.
* Disconnect the power to the dishwasher.
* Disconnect the wires connected to the button terminals (remember their original positions).
* Set your multimeter to the continuity setting.
* Place the multimeter probes on the button terminals.
* With the button not pressed, the multimeter should show no continuity (open circuit).
* Press the button. The multimeter should now show continuity (closed circuit).
* If the button doesn’t change state when pressed, it’s likely faulty and needs to be replaced.
H35. Check the Thermal FuseH3
The thermal fuse is a safety device that protects the dishwasher from overheating. If the dishwasher overheats, the thermal fuse blows, cutting off power to the motor and preventing the dishwasher from starting. A blown thermal fuse is a common cause of a non-starting dishwasher.
* **Locate the Thermal Fuse:** The location of the thermal fuse varies depending on the GE dishwasher model. It’s typically located on or near the motor, behind the lower access panel, or near the control board. Refer to your dishwasher’s service manual or online diagrams for the exact location.
* **Access the Thermal Fuse:** Disconnect the power to the dishwasher before proceeding.
* Remove the lower access panel (usually held in place by screws).
* Locate the thermal fuse. It’s usually a small, white or black, rectangular or cylindrical component with two wires connected to it.
* **Test the Thermal Fuse with a Multimeter:**
* Disconnect the wires connected to the thermal fuse (remember their original positions).
* Set your multimeter to the continuity setting.
* Place the multimeter probes on the fuse terminals.
* A good thermal fuse should show continuity (closed circuit). If the multimeter shows no continuity (open circuit), the thermal fuse is blown and needs to be replaced.
* **Replace the Thermal Fuse:** Purchase a replacement thermal fuse that is specifically designed for your GE dishwasher model. Install the new fuse, connecting the wires to the terminals in the same way as the old fuse. Reassemble the dishwasher.
* **Important:** Before replacing the thermal fuse, try to identify the reason it blew. A common cause is a blocked circulation pump or a malfunctioning heating element. If you don’t address the underlying cause, the new thermal fuse may blow again shortly after being installed.
H36. Inspect the Dishwasher MotorH3
A failing or seized motor can prevent the dishwasher from starting. However, motor problems are less common than other issues like a blown thermal fuse or a faulty door latch.
* **Listen for a Humming Sound:** When you try to start the dishwasher, listen carefully for a humming sound coming from the motor area. A humming sound can indicate that the motor is receiving power but is unable to turn, possibly due to a seized rotor.
* **Check for Obstructions:**
* Disconnect the power to the dishwasher.
* Remove the lower spray arm and the filter assembly to access the sump area.
* Inspect the sump area for any debris or obstructions that may be preventing the motor from turning. Common obstructions include food particles, broken glass, and small utensils.
* Manually try to turn the motor impeller (the part that pumps the water). It should turn freely. If it’s difficult to turn or completely stuck, there’s likely an obstruction or the motor is seized.
* **Test the Motor with a Multimeter (Advanced):** This step requires advanced electrical knowledge and should only be performed by a qualified technician. Testing the motor involves checking the resistance of the motor windings to determine if they are open or shorted.
* **Motor Replacement:** If the motor is seized or electrically faulty, it will need to be replaced. Replacing the motor is a more complex repair that may require specialized tools and knowledge. Consider hiring a qualified appliance repair technician for this task.
H37. Examine the Control BoardH3
The electronic control board is the brain of the dishwasher, controlling all of its functions. A malfunctioning control board can cause a variety of problems, including a non-starting dishwasher. Control board problems are often difficult to diagnose without specialized equipment and knowledge.
* **Visually Inspect the Control Board:**
* Disconnect the power to the dishwasher.
* Locate the control board. It’s usually located behind the control panel or in a separate compartment at the bottom of the dishwasher.
* Carefully remove the control board and inspect it for any signs of damage, such as burned components, swollen capacitors, or broken traces.
* **Check for Loose Connections:** Ensure that all the wires and connectors are securely attached to the control board. Loose connections can cause intermittent problems.
* **Consider Professional Diagnosis:** If you suspect a control board problem, it’s best to consult a qualified appliance repair technician. They have the necessary equipment and expertise to diagnose and repair control board issues. Replacing a control board can be expensive, so it’s important to be sure that it’s the actual cause of the problem before replacing it.
H38. Investigate the Float SwitchH3
The float switch is a safety device that prevents the dishwasher from overfilling. If the water level in the dishwasher gets too high, the float rises and activates the float switch, which shuts off the water inlet valve and prevents the dishwasher from starting. If the float switch is stuck in the “up” position, it can prevent the dishwasher from starting even if the water level is normal.
* **Locate the Float Switch:** The float switch is typically located at the bottom of the dishwasher tub, near the front. It’s usually a small, plastic cylinder or cone that moves up and down.
* **Check for Obstructions:** Inspect the area around the float switch for any debris or obstructions that may be preventing it from moving freely. Remove any obstructions that you find.
* **Manually Test the Float Switch:**
* Disconnect the power to the dishwasher.
* Manually lift the float. It should move up and down smoothly and freely. If it’s stuck or difficult to move, try cleaning it with warm water and a mild detergent.
* Check the switch underneath the float. You may need to remove the lower rack and spray arm assembly to access it.
* Test the switch using a multimeter as described in the door latch section. The switch should be closed when the float is down and open when the float is up.
* **Replace the Float Switch:** If the float switch is damaged or not functioning properly, it will need to be replaced. Purchase a replacement float switch that is specifically designed for your GE dishwasher model.
H39. Timer MalfunctionH3
In older dishwashers, a mechanical timer controls the sequence of the wash cycle. If the timer is malfunctioning, it can prevent the dishwasher from starting or advancing through the cycles. Timers are less common in newer dishwashers, which typically use electronic control boards.
* **Listen for Timer Operation:** When you turn the timer knob to select a wash cycle, listen carefully for a ticking sound. The ticking sound indicates that the timer is running. If you don’t hear a ticking sound, the timer may be faulty.
* **Visually Inspect the Timer:**
* Disconnect the power to the dishwasher.
* Locate the timer. It’s usually located behind the control panel.
* Carefully remove the timer and inspect it for any signs of damage, such as broken gears or burned contacts.
* **Timer Replacement:** If the timer is faulty, it will need to be replaced. Replacing the timer is a more complex repair that may require specialized tools and knowledge. Consider hiring a qualified appliance repair technician for this task.
