If your LG dishwasher LED display is partially out, it can be annoying, especially if you rely on those numbers to track cycles. Even though the dishwasher still works perfectly, missing digits or dim sections can ruin the experience - especially if you like everything working exactly right.
The good news is that this issue is usually fixable with a few targeted checks.
Quick Answer
A partial LED display failure in an LG dishwasher is usually caused by a faulty display panel, loose ribbon cable, or control board connection issue.
Fixing or replacing the display board is often the solution.
Step-by-step solution to fix LG dishwasher LED display issue
Step 1: Power reset the dishwasher
Start simple:
- Turn off breaker
- Wait 5–10 minutes
- Restore power
This can reset minor display glitches.
Step 2: Access the control panel
To diagnose properly:
- Turn off power
- Open the door
- Remove screws holding the control panel
This gives access to the display board and connections.
Step 3: Check ribbon cable connections
The display connects via a cable.
Inspect for:
- Loose connection
- Corrosion
- Damage
Reseat the cable firmly. A loose cable can cause partial LED failure.
Step 4: Inspect the display board
Look closely at the board:
- Burn marks
- Cracked solder joints
- Damaged components
If visible damage exists, the board likely needs replacement.
Step 5: Identify the exact model and part
Your model may also be listed as:
- LG LDS5040ST (alternate reference)
The display/control panel board may be:
- Part #EBR73742804
Always confirm the part number printed on your actual board before ordering.
Step 6: Check the LED screen itself
Sometimes the issue is the display module:
- Look for part numbers on the back of the screen
- Search for replacements using those numbers
However, note:
- Individual screens are rarely sold separately
- Full board replacement is usually required
Step 7: Replace the control panel board
If the issue persists:
- Replace the control panel/display board
- Ensure correct model compatibility
This is the most reliable long-term fix.
Step 8: Reassemble and test
After replacement:
- Reconnect all cables
- Close panel
- Power on and test display
You should see all digits working normally.
Extra tips and best practices
- Take photos before disconnecting cables
- Handle boards carefully to avoid static damage
- Keep connectors clean and dry
- Use original LG parts for best compatibility
- Store your service manual for future troubleshooting
Common mistakes to avoid
- Ignoring loose cable connections
- Replacing parts without checking wiring first
- Ordering wrong part number
- Trying to repair the LED screen directly
- Skipping power safety steps
FAQ
Why is my dishwasher display missing numbers?
It’s usually due to a faulty display board or loose connection.
Can I replace just the LED screen?
In most cases, no. You’ll need to replace the entire control panel board.
Is this issue serious?
No. It doesn’t affect performance, only visibility.
Conclusion
If your LG dishwasher LED display is partially not working, the issue is typically electrical rather than mechanical. Start by checking connections, but if the problem persists, replacing the display/control board is the most effective solution.
Even if the dishwasher works fine, fixing the display restores full usability and peace of mind.
