Finally found a Moccamaster I could afford on my (currently) cheap beer budget. Missing the brew basket and thermal carafe (everyone implies it's not the greatest anyway), so currently using a #4 Melitta cone with it.

First batch, brewed a blend from a local roaster that tends to roast toward the darker side.  WOW,  I could honestly tell an immediate difference. Where normally I could detect no real character in this coffee other than the roast flavor.  This time many more flavors became detectable.  I found myself taking slurps and being somewhat amazed that this coffee was actually better than I had thought.

But back to what this is actually about.

After brewing a few more batches, I noticed the spray arm (?) was getting a bit filthy from coffee splashing up from the brew basket. Naturally I decided to clean it. Now I'm afraid I may have cleaned it too well, as the previously good spray pattern is now gone.

After cleaning I ended up with http://www.flickr.com/photos/moodybrewscoffee/8707264113/

Anyone else observe this behavior ? Did I inadvertently scrub something away ?

It's now back to normal after a bit of creativity, I'll post how later.

Hello,

I've owned my Technivorm KBTS around 7 years. The brewer did come with the newer spray head and does the same thing as your video. What I do is just run tap water through it and rub the holes with a dish washing brush. Do you use reverse osmosis water in your brewer? I have noticed that it might have something to do with that phenomenon. When I first purchase it, it did bother me so I ordered the older single hole version from Holland. I recently went back to the shower head water tube, and guess what, it does the same thing as it did 7 years ago after about 7 cycles. I just take it off and clean it as I describe. When you clean it, don't use anything abrasive, just and brush tap water and maybe dish-washing detergent.  Good luck!

Odd that your's did it from the start. Mine started only after I used one of those green scrub pads. My "fix" was to simply rub a film of vegetable oil on it, and wipe off the excess. Then a few batches of water ran through, I can't taste anything offhand after doing this.  I also think that simply letting it get dirty again, and only wiping it off with a cloth or paper towel would get it right again.  

Did you perceive any difference in taste when you tried the one-hole spray arm ? It looks like it would just bore a hole through the grounds and create a weak brew.

I even pull both plastic end piece off and scrub the inside of the tube with a bottle brush.  And yes, the spray is different right after cleaning but normalizes as I use it.

I have the version with the manual drip switch on the side of the basket.  I start with it closed and after a bit of water has built up in the basket I stir with a bamboo chopstick before opening it up.  After doing that the grounds are completely saturated and I don't worry too much about the drip pattern of the arm....

Hi,

When using the single hole heat/water pipe I really didn't notice any appreciable difference 7 years ago! I do usually tap down the sides of the coffee in the filter holder after about 1 cup has dispersed over the grounds. I never have used any abrasive material to clean the water pipe, just some Dawn and soft brush!
