I have several Washworld machines and when the presoak is applied to the car some of them foam nicely while some just do an OK job. All have the same soap the same size injector .083 dual injector for Hi PH and .086 single injector for low PH. They have the same color tips and the soap tritrates out to the very close to the same. After consulting with Washworld I replaced the Nylon foaming material in the manifolds in the machines that were not foaming as well but this did not help. The pump pressure and air pressure are all set to factory recommendations. I would appreciate any ideas.
