Common Automatic Mahjong Table Problems and How to Fix Them

Problem 1: Tiles Are Jammed

A tile jam is one of the most common problems you may encounter with an automatic mahjong table. Fortunately, the cause may be relatively simple.

Check for Foreign Objects

When dropping tiles back into the table after a hand, small objects can occasionally fall inside by accident.

For example:

• Scoring sticks
• Coins
• Small game accessories
• Other small objects left near the playing surface

If a foreign object enters the table, it may interfere with the shuffling or tile transport mechanism.

What to Do

1. Stop operating the table.
2. Turn off the main power.
3. Unplug the table if necessary.
4. Check your model's manual before opening or removing the tabletop.
5. If access is permitted, locate and carefully remove the foreign object.
6. Return all covers and components to their correct positions before restarting the table.

Problem 2: Tiles Stop During Shuffling

Sometimes the table may begin shuffling normally and then suddenly stop. You may also notice that one side of the table does not build the tile wall correctly.

Common signs include:

• The shuffling sound suddenly stops.
• Tiles do not rise to the playing surface.
• Only one side fails to build the wall.
• The table makes an unusual sound and stops.
• An error light, warning sound, or error code appears.

What to Do

1. Turn off the main power.
2. Wait until the table has completely stopped.
3. Check for visibly jammed or misaligned tiles.
4. If your model's manual allows access, carefully remove the affected tiles.
5. Reset the tiles according to the instructions for your model and restart the table.

If the same problem happens repeatedly, stop troubleshooting and contact your seller or the manufacturer. Repeated jams may indicate an issue that requires further inspection.

Problem 3: The Table Won't Turn On

You've invited friends over for game night, everyone is ready to play, and then you press the power button—nothing happens.

Before assuming there is a serious electrical problem, start with the simplest checks first.

Check the Main Power Switch

Confirm that the table's main power switch is turned on. It may have been switched off accidentally while cleaning, moving, or storing the table.

Check the Power Cable

Make sure that:

• The power plug is fully inserted into the outlet.
• The cable is securely connected to the table.
• No connection appears loose.

Check the Outlet

Confirm that the electrical outlet itself is working. You can test it with another device that you know is functioning correctly.

If you are using a GFCI outlet, check whether it has tripped and follow the outlet manufacturer's instructions for resetting it.

Inspect the Power Cord

Look for visible damage to the power cord. Make sure it has not been crushed under furniture, sharply bent, cut, or otherwise damaged.

If you notice significant damage to the power cord, stop using the table and contact the seller or manufacturer for guidance.

Problem 4: The Table Works, but the Score Display Doesn't

On some automatic mahjong table models, the scoring display may have its own power supply or power switch.

If the table itself operates normally but the score display remains off, check:

• The main table power
• The score display power, if your model has a separate switch
• Any visible cable connections
• Error lights or indicators

Check the instruction manual for your specific model to confirm whether the scoring display has a separate power switch or additional troubleshooting steps.

Problem 5: An Error Light or Error Code Appears

Many automatic mahjong tables have built-in indicators that can help identify where a problem has occurred.

Depending on the model, this may appear as an error number, a flashing light, a warning sound, or a combination of indicators.

Before turning the table off, make a note of:

• The error code or number
• Which lights are flashing
• Any beeping or warning sound
• Which side of the table stopped working

Taking a photo or short video with your phone can be especially useful when contacting the seller or manufacturer.

Error codes and warning indicators vary by model, so always refer to the instruction manual for your specific table rather than assuming that an error number has the same meaning across different models.

Before You Try Again: Quick Troubleshooting Checklist

Before restarting the table, run through this quick checklist:

• No tiles are visibly jammed.
• No foreign objects are inside the table.
• The power cable is securely connected.
• The power cord is not damaged.
• The main power switch is on.
• Any error code or warning light has been recorded.
• The tabletop and covers are correctly returned to position.

If everything appears normal, restart the table according to the instructions provided for your model.

When Should You Stop Troubleshooting?

Basic troubleshooting can solve many simple problems, but there are situations where you should stop using the table rather than attempting to fix it yourself.

Stop using the table if:

• You notice a burning smell.
• You see smoke.
• The power cord is damaged.
• The motor or internal mechanism makes an unusual or severe noise.
• The same error repeatedly returns after restarting.
• The table still does not operate after removing a visible jam.
• You suspect an electrical or circuit board problem.

Still Not Working? Prepare Before Contacting Support

If the basic troubleshooting steps above do not solve the problem, the next step is to contact your seller or the manufacturer.

Before contacting them, prepare:

• Model name
• Serial number
• Purchase date
• Order number, if available
• Error code or warning indicator
• Photos of the table and problem area
• A short video showing the problem
• A clear description of what happened

Providing this information in your first message can make it much easier for the seller or manufacturer to understand the problem.

Final Thoughts

If your automatic mahjong table suddenly stops working, don't immediately assume that it needs a major repair.

Start with three simple areas:

1. Tiles: Check for jams or foreign objects.
2. Power: Check the switch, cable, and outlet.
3. Error Indicators: Record any error codes, lights, or warning sounds.

If these basic checks do not solve the problem, stop troubleshooting and contact your seller or the manufacturer with the information you have collected.

A few careful checks can often identify a simple problem—and knowing when to stop is just as important as knowing what to check.
