Automatic Mahjong Table Interior

Why Might It Get Stuck?

While a high quality automatic mahjong table is designed to last for a very long time. It is possible for a table to get stuck at some point. The most common issue that we face is if there are obstructions within the machine. In most instances, the issue arises from players accidentally dropping chips into the shuffling cabin, which can cause the machine to become stuck. It’s essential to identify the source of the problem before attempting to troubleshoot it.

Apart from obstruction, power failure or malfunction of individual motors can also occur after heavy wear and tear. In instances of power failure, motors may not be getting the necessary electrical power as a result of a loose wire, or a malfunction power supply. It is often useful to establish the cause of the issue in the course of troubleshooting a stuck machine.

In this guide, we will go through some of the basic steps we will recommend, so you too can perform some basic troubleshooting of your own mahjong table.

Step 1: Check the Power Source

If you’re having trouble with your automatic mahjong table, the first step is to check the power source. Here’s how:

1. Inspect the power cord to ensure it’s securely plugged into the table and the outlet. You will be surprised how often this is the cause of it all.

2. Double-check that the outlet is functional by plugging in another device such as a phone charger.

3. If the outlet is working fine, try using a similar 220v computer power cord to power your mahjong table in place of the original cord. This will help you ascertain if the fault lies with your power cord, or with the machine.

If both the outlet and the power cords are fine, it’s time to move on to the next step.

Step 2: Check for Obstructions

The next element to look thoroughly into is for actual obstructions. In instances where machines are stuck but still remain powered, the most common cause of a jam is due to obstruction. You will now need to look into the shuffling mechanism as well as tiles conveyor belt to determine cause of issue.

But before going further, if you are new to the idea of an automatic mahjong table, we do recommend reading this article that explains how an automatic table works, that will give you some background on what to do going forward.

1. Open the Table Playfield

Start by removing the plastic bezel surrounding the mahjong table. This may require a bit of prying depending on how often you open your playfield. Lift or remove your playfield, then prepare to open the shuffling cabin by raising shuffling control panel. This is typically done with power connected. Afterwhich, proceed to shut off the table and unplug the power wires completely. 

2. Inspect the Shuffling Cabin.

After shutting off and unplugging the table, you should check the shuffling mechanism for any debris or small objects that might be preventing tiles from moving or getting stuck in the slots. If you have dropped in metal bits or coins, these might interfere with the magnets within the machine.

3. Check the Conveyor Belt and Moving Parts:

Next, you should check the conveyor belt and other moving parts for any signs of blockage or interference from debris or foreign objects. If there are, look to dislodge the obstructing substances from the conveyor belt.

4. Check the Interior of the Table:

It is important to check the interior of the table too. Make sure that no debris or foreign objects are lodged between the gears or other components, as they may cause obstruction and blockage. Occasionally, chips can fall into this area and that blocks the motors from functioning properly.

5. Check the Tile Tray (Only for Standard Rollout models)

For models with a standard rollout, a misaligned tile tray can sometimes cause the machine to be stuck. The tile tray is basically responsible for pushing the tiles up to the playfield, and occasionally, a tile tray that is bent, or under lubricated can mean that the process of pushing the tiles up is no longer smooth and aligned. Manually lift the tile tray to feel if there are any obstruction and if this process is smooth.

If you have followed these five steps, you would very likely have found an offending element if obstruction is the cause of your table’s malfunctioning. If this does not work still, there a few more areas to look at.

Step 3: Test Run the Table

At this point, if you have have found an issue in Step 3, then you will want to test run the table to see if it works smoothly.

Start by adding the tiles back to the table, followed by installing the detachable playfield back in place. Then power the mahjong table and let the table shuffle the tiles. By this point, you have done the basic checks and should be able to get the table running again if the problem is caused by some basic obstruction. If the problem however persist, it is best to engage a professional to look at your table.

Step 4: Consult Professional Mahjong Technician

After years of usage, some parts of the table may be malfunctioning due to wear and tear, and a proper troubleshooting process by a professional is essential to clearly pinpoint the fault, so to prevent the same issue from occurring again. Some areas that we as a professional will look at will include the sensors, motors, rotating arms and other physical alignment issues. These are specialised areas that will require parts from the original maker. It is always best to use original parts regardless what your technician might say.
