I was washing every Sunday but my hair has always been really greasy and I used to have to wash it every day so I washed it again yesterday and now intend to keep doing it every Sunday and Wednesday. I'm using Dreads UK shampoo at the moment. As soon as it runs out I'm gonna switch to something else but just can't bring myself to throw away a nearly full bottle. As for the water it is really hard in my area.
Im actually washing at a somewhat similar rate, I recommend getting a shampoo from Dreadlockshampoo.com because (although im not familiar with that particular company) alot of shampoos that claim they are for dreads and low/no residue actually have many conditioning agents in them that prevent the dreading process, but as for that gunk in your hair (seeing as that you havn't used wax) its possible that its a buildup of the shampoo you're currently using because another downside to A LOT of shampoos that claim to be for dreadlocks and low/no residue don't wash out completely when using hard water. The shampoos I reccomended on that website have a beer base and are made from distilled water and other natural ingredients that allow it to work in all water types, it really really really is amazing stuff and it smells fantastic too. Its also all natural, not animal tested, no palm oils, etc. The bars on there are for more mature dreads I hear, but alot of their liquid shampoos smell like somthing straight out of a holistic or hippie shop its really great stuff and will help your hair lock in no time. Also, the water in my area is incredibly hard as well and I was having a very similar problem as you where my hair just did not want to lock, despite using a dreadlock shampoo and as soon as I switched to those shampoos I saw the difference after one wash, because what I thought was my hair dreading was really just the product building up which further prevents dreading
