You’re ready to unload your Bosch dishwasher but there’s a snag—the display isn’t working when the door is closed. This can be both confusing and frustrating.
In this article, you’ll find straightforward explanations and practical solutions to get your dishwasher back in tip-top shape.
Common Causes of a Non-Functional Display in Bosch Dishwashers
The Bosch dishwasher display may not work when the door is closed for several reasons.
Electrical Issues
Electrical issues are the most common cause of a non-functional display in Bosch dishwashers. These include:
Circuit Breaker Problems:
If the circuit breaker that supplies power to your dishwasher is tripped or faulty, it may prevent the display from working properly.
This can happen due to power surges, overloading, or wiring faults.
Wiring Issues:
The internal wiring of your dishwasher may be loose, damaged, or corroded, causing a poor connection between the display panel and the main control board.
This can happen due to wear and tear, moisture, or rodents.
Software Problems:
The software that controls your dishwasher may have glitches or errors that affect the display functionality.
This can happen due to firmware updates, power interruptions, or incompatible settings.
Display Panel Failures
Display panel failures are another possible cause of a non-functional display in Bosch dishwashers. These include:
Screen Malfunctions:
It may be difficult to read or touch the display panel if the screen is cracked, scratched, or faded.
This can happen due to physical damage, exposure to heat or sunlight, or aging.
Button Failures:
You may not be able to select or change settings due to broken, stuck, or worn out buttons. This can happen due to frequent use, spills, or dirt.
Mechanical Issues
Mechanical issues are the least common cause of a non-functional display in Bosch dishwashers. These include:
Door Latch:
Dishwasher door latches may be loose, broken, or misaligned, preventing the door from closing properly.
This can happen due to improper installation, slamming, or warping.
Hinges:
Several factors can cause the dishwasher door hinges to sag, rust, or break, interfering with the display.
This can happen due to excessive weight, corrosion, or wear and tear.
How to Troubleshoot Your Bosch Dishwasher Display?
Trying these simple steps can help you troubleshoot your Bosch dishwasher display when it’s closed. Here are some tips on how to diagnose and fix the problem yourself.
Resetting the Dishwasher
Reset your dishwasher by unplugging it for one minute from the power source. Then plug it back in and see if the display works normally.
This may clear any software glitches or errors that are causing the display issue.
Checking the Circuit Breaker
The next thing you should do is check the circuit breaker that supplies power to your dishwasher. Make sure it is not tripped or blown and that it is delivering enough voltage to your appliance.
You can use a multimeter to test the voltage at the outlet where your dishwasher is plugged in. It should be between 110 and 120 volts AC.
If the voltage is too low or too high, you may need to contact an electrician to fix the problem.
Inspecting Internal Wiring
Check the internal wiring of your dishwasher for any loose, damaged, or corroded connections. Remove the lower toe kick panel on your dishwasher to access the main control board.
The ribbon cable from the main control board to the display panel will also need to be accessed. You will need a screwdriver and a pair of needle-nose pliers for this task.
Make sure you disconnect the power before opening any panels and don’t touch any live wires. Look for frayed wires, loose terminals, and green corrosion once you’ve accessed the wiring.
Replace any faulty wires or connections with new ones of the same type and gauge. You can use wire nuts or crimp connectors to join wires together securely.
Testing the Display Panel
The fourth thing you should do is test the display panel for any screen or button malfunctions. To do this, you will need to remove the outer door panel and access the display panel.
You will need a screwdriver and a multimeter for this task. Be careful not to damage the ribbon cable that connects the display panel to the main control board.
You should check the display panel for cracks, scratches, or fading on the screen or buttons. Display panels will need to be replaced if you find any.
You can order a replacement display panel from Bosch or an authorized dealer. Touch the probes of your multimeter to the ribbon cable terminals to test the screen and buttons.
When you press a button or touch the screen, your multimeter should beep. A broken circuit will not beep or display a reading. You will need to replace it.
Software Reset
The fifth thing you should do is perform a software reset on your dishwasher. This may resolve any system glitches or errors that are affecting the display functionality.
Press and hold the Start button for 3 seconds until you hear a beep or see a light flash. Press and hold the On/Off button for 3 seconds until you hear another beep or see another light flash.
Wait for 10 seconds and then turn on your dishwasher again. Check if the display works normally.
Factors to Consider Before Seeking Professional Help
You should consider some factors before calling a technician for a Bosch dishwasher display issue. These include:
Warranty Status:
You may be eligible for free or discounted dishwasher repairs from Bosch. Some repairs may not be covered by your warranty or may void it.
Check your warranty carefully. Contact Bosch or schedule a service visit with your proof of purchase and warranty information.
Cost of Repair vs. Replacement:
There is a range of $150 to $4001 in repair costs, depending on the severity of the display issue.
Compare this cost with the cost of a new dishwasher, which may range from $500 to $20002. Buying a new dishwasher is more economical than fixing the old one.
Availability of Parts:
You may have difficulty finding Bosch dishwasher display parts, especially if your model is older. This may delay your repair process or increase your repair cost.
Before booking a service visit, check if Bosch or an authorized dealer has the parts you need.
Time Required for Repair:
It depends on the availability of parts, the complexity of the issue, and the technician’s schedule. It may take anywhere from a few days to a few weeks for your dishwasher display to be fixed.
Before booking a service visit, consider how long you can live without your dishwasher.
