Frigidaire Dishwasher Blinking Lights: Causes and Solutions
When your Frigidaire dishwasher starts blinking lights, it’s usually trying to communicate a problem. This guide will walk you through common causes of blinking lights and practical solutions to help you resolve the issue. Before diving into troubleshooting, let’s understand that not all dishwasher models have the same blinking light patterns. Always refer to your user manual for specific blinking codes if available.
Common Causes of Blinking Lights in Frigidaire Dishwashers
1. Door Strike Issues
If the dishwasher door isn’t properly sealed, it may trigger a blinking light as a safety feature to prevent water leakage during operation.
2. Clogged or Faulty Float Switch
The float switch monitors the water level inside the dishwasher tub. If clogged or malfunctioning, it can cause a blinking light.
3. Drainage Problems
A blocked drain hose or pump impeller issue can prevent proper draining and result in blinking lights.
4. Faulty Control Board
In rare cases, a malfunctioning control board might cause erratic blinking patterns as it struggles to manage the dishwasher’s functions correctly.
Step-by-Step Troubleshooting Instructions
1. Check Door Latch and Strike
- Inspect: Ensure the dishwasher door closes firmly and latches correctly.
- Test: Open and close the door several times to ensure it locks into place.
- Fix: If the latch seems faulty, adjust or replace it according to your model’s manual.
2. Examine the Float Switch
- Locate: Find the float switch inside the dishwasher tub, usually near the top.
- Clean: Gently remove any debris or food particles obstructing the switch’s movement.
- Test: Run a short cycle to see if the blinking stops; if it persists, proceed to next steps.
3. Inspect Drainage System
- Check Hose: Ensure the drain hose isn’t kinked or clogged; straighten and clean if necessary.
- Examine Pump Filter: Some models allow access to a filter at the bottom front of the dishwasher. Remove and clean it thoroughly.
- Listen for Pump: Run a cycle and listen for the pump engaging; if not, it might need professional attention.
4. Control Board Issues (Advanced)
If you’ve addressed other possible causes without success, a faulty control board could be to blame. In this scenario, calling a certified technician is advisable as it involves internal electrical components.
When to Call a Professional
If the blinking lights persist after trying the above steps or if you are uncomfortable with electrical parts, consult a professional appliance repair technician. They can accurately diagnose and fix complex issues like a malfunctioning control board.
