Every homeowner relies on their dishwasher to keep their dishes sparkling clean and sanitized. However, a blinking red light on your Bosch dishwasher can be a frustrating and puzzling sight. Understanding the meaning behind this flashing signal is crucial for troubleshooting and resolving the underlying issue.
Common Causes of Blinking Red Light
1. Water Supply Issues:
- Blocked or kinked inlet hose: Ensure the hose connecting the dishwasher to the water supply is clear of any obstructions.
- Low water pressure: Check if the water pressure in your home is sufficient. A pressure of at least 20 psi is recommended.
- Faulty water inlet valve: The valve may be malfunctioning, preventing water from entering the dishwasher.
2. Drain Issues:
- Clogged drain hose: Inspect the hose for any blockages or kinks.
- Faulty drain pump: The pump may be unable to drain water from the dishwasher effectively.
- Blocked drain filter: Check and clean the drain filter to remove any food debris or other obstructions.
3. Electrical Faults:
- Power supply problems: Ensure the dishwasher is properly plugged into a working outlet.
- Faulty electrical components: A malfunctioning circuit board or other electrical components can cause the red light to blink.
- Overheating: If the dishwasher overheats, it may automatically shut off and display the red light.
4. Sensor Issues:
- Faulty temperature sensor: The sensor may be malfunctioning, preventing the dishwasher from heating the water properly.
- Leaking door seal: A damaged door seal can allow water to leak out, triggering the red light.
- Turbidity sensor failure: This sensor detects the clarity of the wash water. If it fails, the dishwasher may stop operating and display the red light.
