Doser Blinking Yellow

Hello,

After tinkering with my GHL Doser SA and Slave unit this evening, I noticed that the GHL logo is blinking yellow. I realise that it is a 'warning' blink but I cannot seem to trouble shoot the cause of this.

These are the task I performed on it:
Installed Slave unit
Tried to connect to myGHL - no success
Wifi connection error and fix
Connected via USB
Calibrated all 8 pumps
Commenced dosing on pumps 5 to 8

Is there a log or error message display on GHL Control Centre that identifies the problem?
Any suggestion is greatly appreciated. Many thanks.

Cheers
M

Yellow flashing indicates that one or more of your fluid container levels are running low. Check each of your fluid containers in GCC, app, or myGHL and either refill the dosing containers or set a lower minimum threshold for that dosing pump.

Thank you Vinny.
I had a further look at GCC and corrected the refill amount.
Cheers!
