5 Common ATM Error Codes and How to Fix Them

ATM error codes can help you keep your ATM working properly. No one likes to see an “Out of Order” sign. Customers expect ATMs to be available and functioning when they need cash. And that’s your service—convenient access to their accounts.

So it hurts your business as well when your ATM isn’t functioning. You lose out on transactions, so it’s important to get your machine back up and running as quickly as possible.

It isn’t very common for new ATM machines to malfunction, but anything can happen at any time. So no matter the age of your machine, it’s a good idea to conduct regular servicing and maintenance to keep your machine running for as long as possible with as little downtime as possible.

There are 5 common ATM error codes that you are bound to see throughout the course of your ATM ownership. But they are easy fixes that you can handle yourself. It’s also fairly simple to conduct other troubleshooting if you follow the right steps. Follow this guide as well as the appropriate owner manuals to help.

How to Troubleshoot Your ATM

There are a few simple steps you can take to troubleshoot your ATM if you encounter issues. The first step is to assess the situation. This involves you recognizing that your ATM machine isn’t functioning properly. The first thing you should look for are error codes.

The second step is to identify the problem. You might obviously know what part or function of your ATM machine isn’t working. If not, an error code can help. An error code may or may not identify the problem specifically. If it doesn’t, it should at least guide you in the right direction.

Next, you need to resolve the issue. Consult outside resources such as your ATM manual or an ATM technician to determine the severity of the issue. There are two categories of ATM troubleshooting: first line maintenance (FLM) and second line maintenance (SLM). 

FLM can be performed by the ATM owner or cash loader. Most ATM troubleshooting can be done by the ATM owner by following simple directions associated with the error codes and referencing instructions or using the proper ATM owner manuals. 

Simple issues like paper jams, cash jams, and empty receipt paper you can fix yourself. SLM will need to be performed by a qualified technician. 

Hopefully your problem requires only FLM. Fixing the problem yourself is quicker and cheaper than calling a technician.

But, if the machine needs to be opened up for servicing, you might need SLM. It’s best to call an expert when tools and specialized knowledge are required.

Finally, make sure you document everything. Take note of what went wrong, what action you took, and what the result was. You might need this information later for warranties, equipment audits, or to advise employees when future troubleshooting is necessary.  

5 Common ATM Error Codes and How to Fix Them

The purpose of ATM error codes is to diagnose a problem with your machine. They should guide you to the proper repair strategy. There are dozens of ATM error codes you could come across during your time as an ATM business owner, and they vary by machine.

However, we’ve identified the 5 most common ATM error codes and explained how you can quickly fix them:

1. 40047 – Dispenser Error

This means that there is a cassette misfeed and the dispenser isn’t working properly. To fix the problem, check for bill jam. If no bills are jammed, clean the dispenser sensors. If the problem persists, you may need to exchange the cassette box.

2. 20013 – No Receipt Paper

If you receive this error, one of two things could have happened. One, the receipt paper is empty. Or two, there is a printer jam or some obstruction. If you are still having trouble, try the paper reset switch. The printer may require service if it still isn’t working and your troubleshooting has been unsuccessful.

3. D1500 – Connection Error

This means there’s a modem disconnection or timeout. If the host doesn’t respond in 60 seconds it can result in this error. To fix it, verify the host phone number and modem speed. If they’re consistent, your modem could be defective and you’ll need to contact the telephone company.

There’s also a chance that the modem cannot support the connection or there is excessive line noise (D170x). This happens when the phone line connected to the ATM will not support data-communication. You might be able to fix this with an in-line filter.

Another cause could be excessive EMI transmissions from an outside source such as a neon sign or freezer. Or, it could be a programming issue. Check all programming, especially the Dual Master Key setting and Host Processor Mode.

4. F000F – Incorrect/Empty TID

If the terminal ID (TID) is not set, you will need to do so. This error code is triggered when the TID is not set or is set incorrectly. You can check this in the Host Setup.

5. 20002 – Low Cash or No Cash

You will get this error when the low cash warning sensor on the dispenser is open. If “Low Cash Warning” is enabled in the Transaction Setup menu, this sensor will open when the cassette reaches (+/-) 75 bills. If your machine is typically stocked with a low amount of bills, you might want to disable this function. And of course, to fix this error, feed the ATM!
