GHL Maxi doser 2.2 stalling - unusable

Hello all

After the issue to connect to the WiFi, once done I connected all my tube and went for the calibration. This is when I experienced the repeating stalling of the pump, either the first or second one at any speed.

I thought it would be due to the pump being new and not totally primed. I ran it a few time and still happening with the horrible sound it make.

I took some videos of the issues

The doser is useless like this and it already have the last firmware, what should I do?

Hello,

I'm sorry you are having this issue with your new Doser.

What is the firmware version of the Doser?
The firmware must be 1.44

I got version 1.43, going to upgrade and try again with the 1.44

Where can I find th3 firmware 1.44?
I don’t have a PC, so need by the web

you can find it in the installation path of the GHL ControlCenter like
C:\Program Files (x86)\GHLControlCenter_V1140\Firmware\PAB-Devices
regards Pit

Hello,

Unfortunately, at the moment internal and PAB firmwares update can only be done with the GHL Control Center software on Windows.
Try to borrow a laptop from someone to do this update, otherwise please open a support ticket and ask GHL to perform this update but this will require the doser to be returned to GHL.

I have exactly the same issue on firmware 1.44
If operating manually too it sticks but when you release the button the pump then spins free.

I opened a ticket on 6th Dec but not had a reply from support yet.

Hello Patrick,

This is not normal, I'll take care of escalating your ticket.
Unfortunately this one seems to have been forgotten.
Our apologies.
