I don't remember all the lights mine was doing, it was about a year and a half ago. I read somewhere to clean the filter. I think it's underneath, but I wouldn't swear to it. I don't even remember if we found one. BUT mine started working perfect after I removed the entire soap dispenser and cleaned it thoroughly. No problems at all since then. The dispenser is hard to get out. It feels like it will break if you put pressure on it. Maybe I was being too cautious.
I don't know if it makes a difference but I have never used any detergent other than Splendid.
