Troubleshooting an F16 error on a GE dishwasher may seem daunting, but the solution is often simpler than you might think. From checking the water supply to resetting the appliance, this guide will walk you through the step-by-step process to get your dishes sparkling clean once again. With a little patience and the right know-how, you’ll be back to effortless dishwashing in no time.
What Does the F16 Error Mean?
If you’re troubleshooting a GE dishwasher and you see an F16 error code, don’t worry – it’s a fairly common issue with a relatively simple solution. So, what exactly does the F16 error mean?
The F16 error code indicates that your dishwasher’s internal monitoring system has detected an abnormally high water temperature during a wash cycle. This means the water in the tub has gotten too hot, triggering the dishwasher’s safety precautions.
But why would the water get that hot in the first place? The dishwasher’s heating element is responsible for heating the water to the optimal temperature for cleaning your dishes. If there’s an issue with the heating element or the thermistor (the sensor that monitors the water temperature), it can cause the water to get too hot, leading to the F16 error.
Safety Precautions
Before attempting any troubleshooting or repairs on your GE dishwasher, taking the proper safety precautions is crucial. Dealing with electrical and water systems can be dangerous, so let’s go through the steps you should follow to stay safe.
Disconnect the Power
The first and most important step is to disconnect the power to your dishwasher. You can do this by unplugging the appliance from the wall outlet or by turning off the circuit breaker that supplies power to the dishwasher. This will ensure that you don’t accidentally electrocute yourself while working on the machine.
Allow the Dishwasher to Cool Down
If you’ve recently used the dishwasher, it’s important to let it cool down completely before starting any repairs. The interior of the dishwasher can get extremely hot during a wash cycle, and touching hot parts could result in serious burns. Give the appliance plenty of time to cool down before you start working on it.
Turn Off the Water Supply
Before you begin any repairs, you’ll also need to turn off the dishwasher’s water supply. This is typically done by locating the shutoff valve under the sink or behind the dishwasher and turning it to the closed position. This will prevent water from leaking out and causing a mess while you’re working.
Work in a Well-Lit, Uncluttered Area
When working on your dishwasher, it’s important to have a clean, well-lit workspace. Make sure the area is free of clutter and obstructions, and keep children and pets away to prevent accidents. Good lighting will help you see what you’re doing and avoid making mistakes.
Use the Right Tools and Protective Gear
When working on your dishwasher, it’s a good idea to use non-conductive tools and wear insulated work gloves. This will protect you from electric shocks and other injuries. Avoid touching any exposed wires or terminals, and be gentle when handling or removing parts.
Consult the User Manual
Finally, be sure to refer to your dishwasher’s user manual for any specific installation or safety instructions. The manufacturer may have provided important information that could help you safely complete the repair.
Remember, safety should always be your top priority when working on any electrical or mechanical appliance. By following these simple precautions, you can ensure that your dishwasher repair is done safely and effectively.
Clearing the F16 Error Code
Now that we’ve covered the safety precautions and inspected the thermistor and heater assembly, let’s move on to clearing the F16 error code on your GE dishwasher.
Step 1: Inspect the Thermistor
The first thing you’ll want to check is the thermistor, which is the component responsible for monitoring the water temperature inside the dishwasher.
- Unplug the dishwasher from the power source.
- Remove the lower access panel to gain access to the main control board.
- Locate pins 8 and 7 on connector J711 on the control board.
- Set your multimeter to resistance mode (Ω).
- Check the resistance between pins 8 and 7 using the multimeter probes.
- At room temperature, the resistance should be around 10K-11K ohms.
- If the resistance reading is way off or shows an “open” circuit, it’s time to replace the thermistor.
- If the thermistor tests are good, move on to the next step.
Step 2: Check the Heater Assembly
The next component to inspect is the heater assembly, responsible for heating the water during the wash cycle.
- Visually inspect all the wiring to the heating element, making sure the connections are secure, and there’s no damage.
- With the dishwasher unplugged, set your multimeter to continuity mode.
- Test the heating element wires and terminals for continuity to the metal frame, and replace the element if there’s continuity (indicating a short).
- Check the resistance of the heating element itself, which should be 10 to 15 ohms.
- If everything else passes testing and inspection, the main control board may need to be replaced as a last resort.
By following these steps, you should be able to identify and resolve the issue causing the F16 error code on your GE dishwasher. Remember to work safely, take your time, and refer to your user manual if you have any questions or concerns.

Conclusion
You’ve made it through the step-by-step process of troubleshooting and resolving the F16 error code on your GE dishwasher. Let’s quickly recap what we’ve covered:
- The F16 error code indicates an abnormally high water temperature has been detected during a wash cycle, triggering the dishwasher’s internal safety system.
- It’s crucial to follow proper safety precautions, such as disconnecting power, allowing the appliance to cool down, and working in a clean, well-lit area.
- The first step is to inspect the thermistor, which monitors the water temperature, and check for any issues with the resistance or continuity.
- Next, you’ll want to examine the heater assembly, ensuring the wiring is secure and the heating element is functioning correctly.
- If the thermistor and heater assembly check out, the main control board may need to be replaced as a last resort.
When to Seek Professional Help
While these troubleshooting steps can be a great starting point, it’s important to recognize when a problem may be beyond your DIY capabilities. If you’ve tried all the steps and the F16 error persists, or if you’re uncomfortable working with electrical components, it’s best to consult a qualified appliance repair technician.
They have the specialized knowledge and tools to diagnose and fix more complex issues, and they can ensure the repairs are done safely and correctly. Trying to tackle a problem that’s outside your skill level could potentially lead to further damage or even personal injury.
Remember, the most important thing is your safety. Don’t hesitate to reach out for professional assistance if you’re ever unsure or uncomfortable with a repair. With the right help, you can get your GE dishwasher back up and running in no time!
