Gentle fellows, having moved to a new town where water supply is many times more expensive than before, I purchased a Paterson Auto Print Washer, Major model, to save both water and money. I am, however, in doubt that this nice machine is washing the prints as good as running water. The agitation mechanism works, but I found out that it only works when the water flux is very moderate. So moderate that I ask myself if there is an effective change of water inside the tank during the washing time. If the tap is opened up, the agitation mechanism gets stuck and the rattling noise of (I guess) a steel ball can be heard. Is this condition normal, or has my washer a defective agitation unit? Also, the user's directions sheet says nothing about washing times. I suppose the user shall respect the paper's producer directions, which are usually 40 mins to 1 Hr but are however intended for running water. Is 1 Hr actually sufficient with such a limited fresh water intake? Thanks for reading.
