Hello and Help please!! I have been trying to get my ATL-2300 to work properly since recently installing it. A recurring fault is that the chemicals are not being pumped into the drum. The machine gives a beeping noise and error message that Chemicals have not been successfully pumped. By pressing the 'Start' button it then seems to reactivate the pump and the chemicals are successfully transferred into the drum. I have renewed the red o-ring seals, tested using water in the bottles with no film in the drum with no problems. However as soon as I use E6 (3 bath) chemistry and place film in the drum the fault recurs. I have also removed the cover and inspected the hose-line which all seem properly secured and no damage which might cause a leak. Clearly something is not right and I cannot face hanging around to perform the button pressing at every stage - it rather defeats the object of having an Automatic processor! Originally I thought I had a rogue lid (all had worked fine in my ATL-1000), despite it visually looking like my other ones. I performed successful runs with other lids with water, but this cannot be the case since the problem has just returned using a different lid. Any ideas on things I can check? The manual doesn't give any indication as to where the problem might lie. Neither could I find anything on Jobo-USA website.
