GE Dishwasher Heating Element Test: Easy Troubleshooting
A GE dishwasher heating element is crucial for drying dishes effectively. If your dishes are consistently coming out wet, it could indicate a problem with the heating element. Fortunately, a simple test can help you determine if it’s the culprit. This guide will walk you through performing a "ge dishwasher heating element test" with ease.
Understanding the Heating Element’s Role
The heating element in your GE dishwasher performs two primary functions:
- Drying dishes: After the final rinse cycle, the element heats up, evaporating any remaining water and leaving your dishes sparkling clean and dry.
- Sanitizing: In some models, the heating element boosts the water temperature during the wash cycle to sanitize dishes.
Therefore, if you notice that dishes aren’t drying properly or that the "sanitize" cycle seems ineffective, a heating element problem is a likely possibility.
Safety First! Preparing for the Test
Before you begin any electrical testing, it’s paramount to prioritize your safety.
- Disconnect the power: Unplug the dishwasher from the electrical outlet. Do not just turn it off at the control panel. This is the most important step.
- Turn off the breaker: Locate the circuit breaker that controls the dishwasher and switch it to the "OFF" position. This provides an extra layer of protection.
- Gather your tools: You’ll need:
- A multimeter (digital is recommended for ease of reading).
- Screwdrivers (Phillips and flathead, possibly).
- Pliers (needle-nose pliers can be helpful).
- Safety glasses and gloves are always a good idea.
- Access the Heating Element:
- In most GE dishwashers, the heating element is located at the bottom of the dishwasher tub.
- You may need to remove the lower dish rack and possibly a bottom access panel or shield to gain access. Consult your dishwasher’s user manual for specific instructions.
Performing the Continuity Test
The most common and straightforward method to test a GE dishwasher heating element is a continuity test using a multimeter. This test verifies if there’s an unbroken electrical path through the element.
What is Continuity?
Continuity refers to a complete and uninterrupted electrical circuit. If there’s a break or a short, the circuit is not continuous, and the heating element will not function.
Steps for the Continuity Test
- Set the Multimeter: Turn your multimeter on and set it to the "Ohms" (Ω) setting. This setting measures resistance. Look for the symbol that resembles an Omega (Ω). Some multimeters have an audible continuity setting (often indicated by a sound wave symbol or diode symbol). If yours has this, it can be easier to use.
- Locate the Heating Element Terminals: You’ll see two terminals connected to the heating element. These are usually secured with screws or push-on connectors.
- Disconnect the Wires: Carefully disconnect the wires from the heating element terminals. Use pliers if necessary to avoid pulling on the wires themselves.
-
Test for Continuity:
- Touch one multimeter probe to one heating element terminal and the other probe to the other terminal.
-
Observe the multimeter reading:
- Good Element: If the element has continuity, the multimeter will display a reading between 10 and 30 Ohms. If using an audible continuity tester, it will beep. A low but non-zero resistance reading means the element is likely functional.
- Bad Element: If the multimeter displays "OL" (Over Limit), "Infinity" (∞), or a very high resistance reading (hundreds or thousands of Ohms), it indicates a broken circuit and the heating element is faulty and needs to be replaced. If using an audible continuity tester, it will not beep.
- Double-Check: Perform the test a couple of times to ensure your readings are consistent.
Testing for Grounded Element (Short to Ground)
Another potential issue is a "grounded" heating element. This occurs when the heating element’s internal wiring shorts to the metal casing of the dishwasher, creating a dangerous electrical hazard.
Why is a Grounded Element Dangerous?
A grounded element can cause the dishwasher to trip the circuit breaker or even deliver an electric shock if someone touches the dishwasher’s metal parts.
Steps for Testing a Grounded Element
- Keep Multimeter on Ohms Setting: Ensure your multimeter is still set to measure Ohms (resistance).
- Touch One Probe to a Terminal: Touch one multimeter probe to either of the heating element terminals.
- Touch the Other Probe to the Dishwasher’s Metal Frame: Carefully touch the other multimeter probe to a clean, unpainted metal part of the dishwasher’s frame or chassis.
-
Observe the Reading:
- Good Element: The multimeter should display "OL" (Over Limit), "Infinity" (∞), or a very high resistance reading. This indicates no continuity (no electrical connection) between the heating element and the dishwasher’s frame, which is what you want.
- Bad Element (Grounded): If the multimeter displays a reading close to zero (or any low resistance reading) or if it beeps on a continuity setting, it means there is a short circuit between the heating element and the dishwasher’s frame. The heating element is grounded and needs to be replaced immediately.
Interpreting the Results: A Quick Reference Table
| Test Performed | Multimeter Reading | Result | Action |
|---|---|---|---|
| Continuity Test | 10-30 Ohms (or beep on continuity setting) | Good Heating Element | No action needed (element likely functioning correctly) |
| Continuity Test | OL, Infinity (∞), or very high Ohms (no beep) | Bad Heating Element (open circuit) | Replace the heating element |
| Grounded Element Test | OL, Infinity (∞), or very high Ohms (no beep) | Good Heating Element (not grounded) | No action needed (element not causing a ground fault) |
| Grounded Element Test | Reading close to zero (or beep on continuity setting) | Bad Heating Element (shorted to ground) | Replace the heating element immediately and discontinue use of appliance |
After the Test: Reconnecting and Next Steps
Once you’ve completed the "ge dishwasher heating element test" and interpreted the results:
- If the element is good: Reconnect the wires to the heating element terminals securely. Reassemble the dishwasher. Restore power by switching the breaker back on and plugging in the dishwasher. The problem likely lies elsewhere (e.g., thermostat, control board).
- If the element is bad: Order a replacement GE dishwasher heating element that is compatible with your dishwasher model. Replace the faulty element following the manufacturer’s instructions. Restore power and test the dishwasher to ensure it’s functioning correctly. Remember to unplug the dishwasher and turn off the breaker when replacing the heating element.
GE Dishwasher Heating Element Test: FAQs
Here are some common questions about testing your GE dishwasher heating element to help you troubleshoot potential issues.
Why is it important to test my GE dishwasher heating element?
Testing the GE dishwasher heating element is crucial because it’s responsible for heating the water. If it fails, your dishes won’t get properly sanitized or dried, leading to unclean and potentially unsafe results. A simple GE dishwasher heating element test can pinpoint the problem quickly.
What tools do I need to perform a GE dishwasher heating element test?
You’ll primarily need a multimeter. This tool measures resistance (ohms), which is essential for determining if the heating element is functioning correctly. Safety glasses and gloves are also recommended for safety precautions while working with electrical appliances.
What resistance reading should I expect when testing my GE dishwasher heating element?
Typically, a functional GE dishwasher heating element will show a resistance reading between 15 and 30 ohms. A reading of zero or infinite ohms usually indicates a faulty element that needs replacing. Always refer to your dishwasher’s service manual for specific values.
What if the GE dishwasher heating element test shows the element is fine, but my dishes are still not drying?
If the GE dishwasher heating element test passes but your dishes aren’t drying, the issue might lie elsewhere. Check the thermostat, high-limit thermostat, or control board for potential problems. Also, ensure the dishwasher isn’t overloaded and the rinse aid dispenser is full.
Hopefully, you’ve now got a good handle on performing a ge dishwasher heating element test. Give it a shot, and you might just save yourself a service call! Good luck, and happy dishwashing!
