TMC Dosing Pump not pumping

[sam00skelo]

Hi folks,

I've just been given a second hand TMC Easi Dose. I've been trying to set it up but 2/3 of the pumps don't work. I've pulled it apart and changed doser heads and found that the issue seems to be with the motor driveshafts not catching onto the dosing wheels? Anyone got any ideas on how to get them working?
Thanks,
Sam

May have to replace head (Amazon or eBay). You can try changing tube or blowing through it to assure it’s not clogged and verify the motor is working
