frigidaire dishwasher lights blinking | How To Diagnose And Fix
Try these fixes if your Frigidaire dishwasher is having trouble starting or if certain lights keep flashing annoyingly.
Reset the dishwasher
When the dishwasher won’t start and the lights are just blinking, try to reset the dishwasher first. Because resetting it to defaults often does the trick.
So, how do you reset a Frigidaire dishwasher that is flashing light?
You need to power off/unplug for at least 5 minutes and turn it on again.
Now that your dishwasher has been reset to default, you can select a new wash cycle.
If the still lights are blinking, consider the following fix:
Dishwasher Door Is Open
If the door is not closed correctly, the Frigidaire dishwasher may display a flashing or blinking light and not start the wash cycle. A securely closed door ensures that the water or liquid inside the dishwasher won’t leak out and flood your home.
Even though you believe you have closed the dishwasher door, the door switch might not be activated to signal that the door is indeed closed. This can occur if the latch on either side fails to engage. Take a moment to check for any obstruction, debris, or broken parts in the latch that might prevent the door from properly closing.
If everything is in order, use a multimeter to check the electric continuity of the door switch and ensure the circuit is functioning correctly.
Tip: After closing the door, you may hear a clicking sound indicating the latch is engaged.
Heating Element
The heating element is an essential component of the Frigidaire dishwasher, typically located at the bottom beneath the rack.
Its primary function is to heat the water during the washing cycle, as hot water effectively removes stains and food particles from dishware.
While a malfunctioning heating element can make the water lukewarm, the water cannot attain the temperature required for dish cleaning.
If your dishwasher is not heating up properly, the temperature sensor may not be sensing the right temperature. When this happens, the light in the dishwasher will flash or blink. Over time, the heating element can become defective from overheating and burnout.
Therefore, it’s essential to check the condition of the heating element.
You should remove the elements from the dishwasher and visually inspect them for any broken, burnt, or damaged parts. Then, use a multimeter to test whether electricity still flows through the heating element. If there is no continuity on the multimeter, you must replace the heating element.
However, sometimes the heating element may be in good condition. In this case, ensure the device fits nicely into the tub and that the electrical connections are exemplary.
Defective Control Panel and Touchpad
A problem with the control panel may cause the issue. If you feel confident enough to fix your control panel yourself, try the following:
Access the control panel area through the front panel to address the issue. Clean any corrosion off the ribbon cable connectors. Specifically, the cable connected to the touchpad. Additionally, ensure that all connections are tightened, as a loose connection could be the root cause of the problem with the panel.
Sometimes, when the unit is not working, the control panel is broken and needs to be replaced entirely. In some cases, replacing the touchpad and the control panel may also be necessary to solve the issue.
Here’s a quick tip to keep in mind. Remember, both components may require replacement to fix the problem.
Water and a clogged drain System | Frigidaire dishwasher all three lights blinking
Suppose you encounter a situation where all three dishwashers wash, clean, and sanitize lights are flashing or blinking in your Frigidaire dishwasher. In that case, you won’t be able to restart the washing cycle.
This issue is usually caused by water accumulation in the bottom of the drain system, which clogs the drain filter and triggers the appliance to display flashing lights.
The solution is simple. You must clean the drain system and remove any water and debris clogs. Here’s a step-by-step process to follow:
- To access the drain area, start by pulling out the lower rack of your appliance. You should locate a circular drain filter.
- This filter has a small side branch that needs to be pushed down and turned to the side simultaneously to remove it.
- Remove clogs, food particles, and residue buildups from the filter and drain.
- After removing the filter, you should locate the trap. Take out the trap and the circular cover.
- Look for any standing water or debris inside. Clean the trap thoroughly to ensure that there are no clogs.
- Inspect the small holes of the removed parts for any clogs, and clean them if necessary. Sometimes, the lights continue to flash due to clogs in these tiny holes.
- Make sure to put the trap and filter back in their respective places. Ensure that they fit securely and are aligned correctly.
- To lock the filter, push it down and turn it to secure it in place.
- After reassembling everything and cleaning it thoroughly, start a test cycle on your dishwasher to confirm that the problem has been resolved.
Faulty Control Board
If you notice a flashing or blinking light on your Frigidaire dishwasher, a faulty control board may cause the problem. This can lead to better communication between various components and result in further issues.
For instance, a defective PCB, which is the central part of the control board, may cause the dishwasher to have no lights or only flashing lights. Additionally, issues with the PCB could lead to other problems, such as random beeping, the dishwasher going completely dead, or the wash and clean lights not remaining lit at the end of the cycle.
It’s important to note that the control board may also face problems due to short circuits or excessive heat. Replacing this part of the dishwasher can be expensive.
As a more cost-effective solution, you can hire a technician to diagnose and fix the problem.
