LEDs Not Working

LED Troubleshooting Steps

Checking LED Functionality

Your Argos LEDs should all flash in the following situations:

When you power on the machine
When you run the Argos LED Test via the app:
1. Open the Odyssey Espresso App
2. Go to Settings → Manage Argos → Test LEDs ON

If all LEDs flash as expected, then any unusual LED behavior is likely caused by a software fault or by other hardware components. Refer to this table for details on what specific LED patterns may indicate.

Heat Soak Failure

If any of LEDs do not flash during the above situations then its likely they failed. Unfortunately this is a known issue where the brew temp and steam LEDs fail due to heat soak from the top late and it affects a not insignificant number of machines.

Free Repair Parts (LED Light Tubes)

We're shipping a solution right now that uses light tubes to relocate the LEDs further away from the boiler so that they do not fail. We expect this to be a long term fix.

Here is a link to complete your repair parts order which also include the pin removal tool. Your parts have been covered under warranty. You can add other parts to your order as well to ship at the same time.

Here is an installation guide on the LED light tubes: https://help.odysseyespresso.com/article/64-led-light-tube-installation.

Other Sources of LED Issues

If you already have LED light tubes installed then you may experience another issue.

⚠️ If one or more LEDs fail to light up during the test above, then remove the back and left side panel (facing the machine) and check the following

🔗 How to Remove Panels on the Argos (Video Guide)

Are the wires kinked?

TRY: Straightening out wires and re-do LED test

Are the LED pins going into the 18 pin-connector snug?

TRY: Re-sit pins in 18-pin connector and re-do LED test

Does gently wiggling the relevant wires make a difference?

TRY: Ensure pins in 18-pin connector are not failing to lock into place

If pins are not locking in - follow this guide on how to adjust pin locking tabs

Are there signs of moisture that might be impacting the circuitry?

TRY: Please add Leak Troubleshooting to your to-do list to ensure moisture does not impact other parts of your machine

Do the LEDs work with the back panel removed?

TRY:

Adjusting the wires coming out of the 18-pin connector to minimise pressure from back panel
Adjusting the back panel, ensuring it is not bent too far inwards and exerting excess pressure on the wires exiting the connector

NOTES:

You only need to remove the left panel (looking from the front of the machine) and the back panel to access the relevant wires. If your steam wand is on the left, note that there may be some residual water in the system upon disassembly.
If your LED only fails at high temperatures (e.g., steam temperatures), first check that the LED wire isn't pinched against the boiler insulation and overheating. Since the PCB mount is flexible, you can gently bend it back to create more space for the wires, preventing them from pressing against the hot boiler insulation.

Using the App

While you wait for your LED replacement, data from the Odyssey Espresso app becomes especially valuable, as it shows when the machine has reached the desired temperature.
