Machine Not Heating / Boiler Stalling
⚠️ THIS PAGE IS A WORK IN PROGRESS
For more guidance on this topic, please email us at support@odysseyespresso.com
The below are possible reasons why your Argos is not heating to desired temperature
We recommend testing the below in the order they are listed to systematically exclude the root cause of your issue
| Scenario | Check | Fix |
| No power output at connected power outlet | Test other outlets | |
| Boiler is overfilled - unable to continue to heat due to false pressure | open the steam valve to purge air out and see if this fixes the issue and allows the boiler the continue heating. If this works, it is likely an overfilled boiler causing false pressure | Do not overfill boiler |
| Low boiler LED is not functioning but boiler water level is low, heating element is turned off for safety | check boiler use LED test app |
Refill boiler replace low boiler LED |
| Machine is reporting low boiler however boiler level is full | Fluid probe issue | How to troubleshoot and repair fluid probe |
| Temperature sensors not reading, heating element turned off for safety | Replace grouphead thermocouple email us at support@odysseyespresso.com |
|
| Unable to heat to Steam Temperature due to faulty temperature knob/potentiometer | use app and see if clicking temp knob changes boiler temp target - if temperature targets don't change, potentiometer is not working | email us at support@odysseyespresso.com for replacement part |
The below troubleshooting steps require removal of the side panels
| Scenario | Check | Fix |
| Incorrect Heating Element installed (eg 240v instead of 120v) | How long does it take for the boiler to reach temperature? Taking longer than expected can indicate that your machine has the wrong heating element installed. Using a multimeter, check the resistance of the heating element.

| Faulty Power Switch | Multimeter to test power switch (link below with photo) switch should have a nice discernible click check for signs of short circuit (blackening at spade connectors) |
replace switch |
| Misc Connection issues within the machine | Check for signs of smoke/blackening/short circuit. Look at the wires coming from the power switch or the outlet, as well as the PCB itself on both sides. | Take some well lit photos for us so we can also have a look |
| Faulty Solid State Relay | https://help.odysseyespresso.com/article/46-replace-the-solid-state-relay | |
| Faulty PressureStat | Multimeter testing | |
| Heating Element Malfunction | Using a multimeter, check the resistance of the heating element.
While the machine is off, remove the boiler cap and take a well lit photo if what the inside of the boiler looks like - send us photos |
send photo to support |
Faulty Solid State Relay
- Run the machine with the back cover off. When the boiler stops heating but is not at desired temp, check to see if the green light on the SSR is still lighting up.
- If the SSR LED is lit, we know it's getting signal to heat but is not heating for some reason (this indicates a possible issue with the heating element)
- If the SSR LED is turned off, it means the element is not being told to heat up
Multimeter testing of SSR and PStat
set multimeter to check for voltage reading (120v AC or 240v)
| Multimeter Black Probe Placement | Multimeter Red Probe Placement | If voltage reading is present: |
| black 90 deg spade connector of the IEC power plug socket in the back cover. | SSR's high voltage inlet | confirms we're getting power from the source and through the PCB) |
| black 90 deg spade connector of the IEC power plug socket in the back cover. | SSR high voltage outlet to pstat | confirms SSR is passing power through itself) |
| black 90 deg spade connector of the IEC power plug socket in the back cover. | PStat outlet to heater | confirms pstat is passing power to heating element) |
We want to see where the power stops showing up to diagnose which part is failing.
