Common Causes of Haier Washing Machine Display Issues:
Nowadays all Haier washing machines come with a digital display that should be working to operate the machine. You need to inspect some parts of your device to address the root cause of the Blank display.
Here are some causes that could be the reason behind the non-working display on your Haier Washer:
Power Supply Issue:
You probably know that electronic devices like washing machines require electric power to get started. In case the wall outlet is not supplying power to your unit, its display can’t work. Try to inspect the outlet, and power cord to verify if the power supply issue is there or not. Moreover, the display of your Haier washer is connected to the printed circuit board through wiring. In case any wire is broken or has a loose connection, it will fail to supply the power and output to the screen and cause a blank display issue.
Fault in Printed Control Board:
There is a printed control board located inside the Haier washing machine which is responsible for operating every output component on the device including the display. Sometimes short circuits or heating damage MOSFETs and capacitors like tiny parts on the printed control board which makes it faulty. This type of issue leads the washer not to turn on or display issues. Unfortunately, it requires professional repair by a qualified technician to fix the PCB-related issues. Most of the time this part requires replacement.
Damage Display:
Liquid Crystal Display) panels used in washing machines are made using a complex process involving several layers of materials and precise technology, such as Substrate Preparation, Alignment Layer, Cell Spacers, Liquid Crystal Material, Color Filters, Thin Film Transistors (TFTs), Polarizing Layers, Sealing, Backlighting and Driver ICs. If any part gets damaged, this will make the display faulty and unresponsive. In such a case, the owner needs to replace the display after testing it.

Step 2: Check the Printed Control Board
- Unplug the washing machine again for safety.
- Locate the printed control board inside your Haier washing machine. It’s typically found behind the control panel.
- Inspect the printed control board for any visible signs of damage, such as burnt components or charred areas. If you notice any damage, the control board may need replacement. This typically requires professional repair by a qualified technician.
- Check for loose connections or disconnected wires on the printed control board. Reconnect any loose wires.
- Plug the washing machine back in and turn it on to see if the display now works. If the issue persists, move on to the next step.
Step 3: Inspect the Display
- Ensure the washing machine is still unplugged.
- Carefully remove the display panel or access cover to access the display.
- Examine the Liquid Crystal Display (LCD) panel for any physical damage, such as cracks, scratches, or visible defects.
- If you find any damage to the display, it will likely need replacement. Contact Haier customer support or a qualified technician to order and install a new display.
- If the display appears undamaged, reassemble the washing machine and plug it back in.
- Turn on the washing machine to check if the display is now functioning correctly. If the issue persists, consider seeking professional assistance.
NOTE: If you are not confident in your abilities, it’s best to contact a qualified technician or Haier customer support for further assistance. Additionally, always ensure the washing machine is unplugged before attempting any repairs.
Preventative Maintenance Tips for Your Haier Washing Machine Display:
One important thing to do is to clean the screen regularly. You can use a soft cloth to gently wipe the screen and the area around it. This will help keep it looking nice and working well.
It’s also important not to use strong or harsh cleaning products. These can be too rough and might end up damaging the screen. So, stick to milder and gentler cleaners when you need to clean it.
If you want extra protection for the screen, you can think about getting a screen protector. It’s like a thin sheet that goes on top of the screen to prevent scratches and spills from causing damage.
You should always avoid spilling liquids on or near the display. If you spill something on it, it can cause problems and might even stop it from working.
