I just got a new suds saver hose so I hooked it up and bad news. Even with the switch set for "save suds" it drains out of the main hose which is suppose to be in the stand pipe. When I set it to "return suds" the machine sucks through the stand pipe hose again and not the suds return hose. Any tips or things I should be looking at to fix this problem? Any help would be wonderful!
