One way to tell that your dishwasher is on is by checking the lights on the display or buttons. Without these lights, the appliance will appear dead, even when on. The bad news is that if your dishwasher control panel isn’t lighting up, you can leave it on for long hours. This will, in turn, consume a lot of electricity.
In most cases, Bosch dishwasher no lights on control panel means there’s an issue with the power supply. Control panel problems can also cause this issue to arise. It is worth noting that checking lights on the control panel is not the best way to tell if your Bosch dishwasher is on or off. Stay tuned to understand why a Bosch dishwasher may not display lights on the control panel.
Why Is My Bosch Dishwasher Display Not Working?
A dishwasher control panel has light-emitting diodes underneath. The sole function of these diodes is to light up the digital display and the buttons of the dishwasher. By lighting up, the diodes state that the appliance is on and displays the active functions. So, if your Bosch dishwasher display is not working, one of the following could be the issue: –
1. Power supply issues
The light-emitting diodes beneath the control panel need electricity to light up. If there is a power supply problem, such as no electricity reaching the diodes, the display will not work.
2. Faulty control panel
The absence of light on the display may make the Bosch dishwasher completely dead, or so you may think. Even so, it could be an issue with the control panel. For instance, if the light-emitting diodes on the control panel blow out, the display will not light up regardless of the presence of power. Other control panel components may also be faulty, causing the whole display not to light up.
3. Faulty control board
The main circuit board powers the dishwasher’s functions, including the control panel’s lighting. If it has a problem, you may notice that the dishwasher won’t turn on the lights.
4. Control Panel child lock is on
The Bosch dishwasher has a child lock safety feature. This feature prevents unsupervised children from turning on the appliance and running dishwasher cycles. Activating this feature cuts off the power supply to the appliance. This means that whenever the child lock feature is active, there will be no light on the control panel.
5. Blown fuse
The thermal fuse blows up whenever the dishwasher’s internal temperature exceeds the higher limit to cut off the power supply. In such a case, the control panel display will also not light up due to lack of power.
6. Door not closed
The Bosch dishwasher has one great safety feature that ensures that the appliance only turns on when the door is closed properly. Thus, no control panel lights could indicate that you haven’t latched the door well.
Bosch Dishwasher No Lights on Control Panel: Troubleshooting Tips
As discussed above, various issues can cause the Bosch dishwasher’s no lights on the control panel problem. It’s up to you to troubleshoot the dishwasher and devise a perfect solution for it. Check out some awesome troubleshooting tips for a Bosch dishwasher with no lights on the control panel.
Fix the power supply
If power is not reaching the dishwasher, you should consider resetting the circuit breaker in your consumer unit. To achieve this, turn off the circuit breaker switch, wait for about a minute, and turn it back on.
Or, you can remove the fuse and put it back in place after a few seconds. If these actions don’t solve the problem, check for connection issues. Such include loose power cables, disconnections, and low power supply.
Fix faults in the main control board
Check out for any faults in the main dishwasher control board and fix them. These could be anything from loose connections to burnt components such as resistors. Take note that the problem could sometimes be too big to fix; in such a case, replacing the whole control board would be ideal.
Reset the control panel
Digital devices need resetting once in a while to ensure proper functioning. Remember, you can always reset the control panel to see if the lights come back on.
If resetting doesn’t solve the problem, it shows that there is a bigger issue. In such a case, check for loose or cut connections between the control panel and the main dishwasher control board. Fix any loose connections and test if the panel lights up. If the problem persists, consider replacing the whole control panel.
