Why Are Your Frigidaire Dishwasher Lights Flashing
Various issues can trigger flashing lights on your Frigidaire dishwasher. Here are some of the most common culprits:
- Door Latch Issues: A common reason for flashing lights, especially the “Start/Resume” light, is an improperly closed door or a faulty door latch mechanism. The dishwasher needs to detect that the door is securely shut before it can begin or continue a cycle.
- Water Supply Problems: If the dishwasher isn’t getting enough water, or if the water inlet valve is malfunctioning, lights might start flashing. This can prevent the wash cycle from starting or completing.
- Drainage Issues: A clogged or restricted drain line, or a faulty drain pump, can also cause flashing lights. The dishwasher won’t proceed with a cycle if it can’t properly drain water.
- Temperature Problems: The “Clean” light flashing often points to issues with water temperature. If the water isn’t heating to the required temperature for the selected cycle (especially high-temperature or sanitize cycles), the dishwasher will indicate a problem. Similarly, a flashing “Sanitize” light means the sanitization temperature was not met.
- Control Board or Keypad Malfunctions: Sometimes, the issue lies within the dishwasher’s internal electronics. A shorted keypad, a stuck button, or a malfunctioning main control board can cause erratic light behavior and prevent the dishwasher from operating.
- Power Failures or Surges: A brief power outage or a power surge can sometimes cause the control panel to display error codes or flash lights. This can often be resolved with a simple reset.
- Heating Element Failure: If the heating element responsible for warming the water is faulty, the dishwasher may struggle to reach the proper temperature, leading to flashing lights.

Frigidaire Dishwasher Flashing Lights: Step by Step Fixing Guide
Before calling for service, try these common troubleshooting steps to resolve flashing lights on your Frigidaire dishwasher.
1. The Essential Power Reset
Many electronic glitches can be cleared with a simple power reset. This is often the first step to take for any appliance issue.
- How to do it: Unplug your dishwasher from the power outlet. If it’s hardwired, go to your home’s electrical panel and flip the circuit breaker for the dishwasher to the “OFF” position. Wait for at least one minute. Then, restore power by plugging it back in or flipping the breaker back “ON.”
- What it does: This process drains any residual electrical charge and allows the control board to reset itself, often clearing temporary errors.
2. Check the Door Latch
A common reason for flashing lights, especially the “Start/Resume” button, is an open or improperly latched door.
- How to do it: Open the dishwasher door fully, then close it firmly, ensuring you hear a click as it latches. Inspect the latch assembly for any obstructions, food debris, or visible damage.
- What it does: The dishwasher’s safety mechanism prevents operation if the door isn’t completely closed, and a faulty latch won’t signal “closed” to the control board.
3. Inspect Water Supply and Drainage
Issues with water flow can trigger various error codes and flashing lights.
- Water Inlet:
- Ensure the water supply valve to the dishwasher is fully open.
- Check for any kinks or obstructions in the water inlet hose.
- Test the water temperature from your kitchen sink; if it’s too cold (below $120^\circ$F or $49^\circ$C), increase your water heater setting.
- Drainage:
- Locate and clean your dishwasher’s filter. Food debris and grease can easily clog it, preventing proper drainage.
- Check the drain hose for kinks or blockages. Ensure it’s properly connected to your sink’s drain or garbage disposal. If connected to a disposal, ensure the knockout plug was removed during installation.
4. Check the Control Panel and Keypad
Sometimes, a stuck button or a faulty keypad can cause erratic flashing.
- How to do it: Gently press each button on the control panel to ensure none are stuck in an “on” position. If any buttons feel stiff or unresponsive, this could be the source of the problem.
- What it does: A continuously pressed or shorted button can confuse the dishwasher’s control system, leading to flashing lights and non-responsiveness.
5. Specific Light Patterns and Error Codes
As mentioned in the table above, different light patterns can signify distinct issues. If your dishwasher has a digital display, note down any alphanumeric codes. Refer to your Frigidaire owner’s manual or the table provided for specific meanings and troubleshooting steps.
6. Consider Professional Help
If you’ve tried all the above troubleshooting steps and the Frigidaire dishwasher flashing lights persist, it’s likely a more complex internal component failure. This could include:
- Faulty Door Latch Assembly: If the latch itself is broken, not just obstructed.
- Defective Water Inlet Valve: If it’s not allowing sufficient water flow.
- Burned Out Heating Element: This requires testing with a multimeter.
- Malfunctioning Drain Pump: If the motor has failed.
- Damaged Main Control Board or User Interface Control: These are the “brains” of your dishwasher, and their failure can cause widespread issues.
- Wiring Issues: Loose or corroded wiring can interrupt signals.
Attempting to replace these components yourself without proper knowledge can be dangerous and may void your warranty. It’s best to contact a qualified appliance repair technician.
Cost of Repair: What to Expect
The cost to fix flashing lights on a Frigidaire dishwasher varies greatly depending on the cause and whether you perform the repair yourself or hire a professional.
Component to Replace | Estimated Part Cost (USD) | Estimated Professional Repair Cost (Parts + Labor, USD) |
|---|---|---|
Door Latch | $20 – $70 | $100 – $200 |
Water Inlet Valve | $30 – $80 | $120 – $250 |
Drain Pump | $40 – $100 | $150 – $300 |
Heating Element | $50 – $150 | $180 – $350 |
User Interface/Keypad | $60 – $150 | $150 – $350 |
Main Control Board | $100 – $300 | $200 – $500+ |
Note: These are estimates and can vary based on your specific Frigidaire model, geographical location, and the service provider.
For minor issues like a clogged filter or a simple power reset, the cost is effectively zero. However, for internal component failures, the cost of parts plus labor can add up. Sometimes, especially for older dishwashers, the repair cost might approach or exceed the cost of a new, entry-level appliance, making replacement a more sensible option.
How to Keep Your Frigidaire Dishwasher Healthy
Regular maintenance can significantly reduce the chances of your Frigidaire dishwasher developing flashing light issues and extend its lifespan.
- Clean the Filter Regularly: Most Frigidaire dishwashers have a removable filter at the bottom. Clean it weekly or bi-weekly to prevent food debris buildup, which is a major cause of drainage problems.
- Scrape Dishes: While dishwashers are efficient, scraping off large food particles before loading helps prevent clogs in the drain line and filter.
- Use Rinse Aid: Rinse aid not only helps with drying but also prevents water spots and can improve overall wash performance, potentially preventing temperature-related issues.
- Run Hot Water Before Starting: Before running a cycle, especially a high-temperature one, run the hot water at your kitchen sink for a minute or two. This ensures hot water is readily available, helping the dishwasher reach target temperatures faster.
- Avoid Overloading: Overloading can obstruct spray arms and lead to improper washing and draining, potentially causing issues.
- Periodically Clean with Dishwasher Cleaner: Use a specialized dishwasher cleaner (like a descaler) every few months to remove mineral buildup and detergent residue.
