Bosch Dishwasher: indicator light not functioning
What is this symptom?
If your Bosch dishwasher's indicator light isn't functioning, it means you're not seeing any visual cues during wash cycles. This could be due to a failed InfoLight LED, a control panel issue, or a blown thermal fuse. Addressing these issues can restore visibility and ensure your dishwasher operates smoothly.
Important Tips for Bosch Models
- Bosch dishwashers use an InfoLight (projected floor light) as an indicator; this is separate from control panel lights and may fail independently.
Possible Causes
Failed InfoLight LED or lamp assembly
How to Identify: Dishwasher runs normally (motor, water flow, cycles complete but no projected red light or indicator LED is visible.
Part: InfoLight LED module / projector
Control panel or main control board fault
How to Identify: No control panel lights or indicator lights on the front; dishwasher may not respond to inputs or show signs of power.
Part: Control panel electronics / main board
Thermal fuse blown
How to Identify: Dishwasher stops mid-cycle or shows no power to lights but may have previously overheated.
Part: Thermal fuse (behind control panel)
DIY Solutions
Check and Replace InfoLight LED Module
- Ensure dishwasher is off and unplugged from power.
- Locate the InfoLight LED projector (floor light) typically mounted at the bottom corner of the dishwasher.
- Inspect the LED assembly for damage or loose wiring.
- If accessible, remove and replace the LED with a compatible replacement unit.
