This is what my coffee bed looks like after brewing.  The pick is not the best but it shows a large center hole with the the coffee pushed up the sides.  I am using a Baratza Virtuoso on setting 24 but I have tried some other settings as well.  Does this  seem normal?  I saw some pics on line of the grounds bed and they seem pretty much flat after brewing.  Any ideas?  The filters are white Melitta.

Thanks,
Matt

Never used the Bonavita, but a convex bed is typical of any pouring style that focuses on the center of a cone. Give it a stir once all the water has been deposited and that should give you a flat bed.

I would *guess* it's a grind issue.  Do a little more experimenting.

I have tried different grinds without a lot of luck.  I do have some new filters coming  today to try (Filtropa's).  If I pull the carafe right after the water stops flowing from the spray head it alomost looks level but what actually is happening is that their is a lot of water in the center that has not drained out yet.  As that water slowly drains it leaves the middle like it looks in the pic sometimes worse.  The strange thing is every once in awhile it will be a more flat bed.  I usually try to use a setting between 22 to 24 on my grinder but I have gone coarser with the same result.  I am not sure what setting other typically use.  Thanks for all the help.

I am guessing this is a bloom issue.  One clue is the "foam" on top of the grounds in your picture, that doesn't usually happen with older coffee.  Very fresh beans (within 4 days or so of roasting, less so after that, although it depends on the bean and roast levels) will foam up the moment hot water hits them.  This causes them to float.  You can get underextraction this way if you don't stir the grounds up and break up the foam.  This could also explain why sometimes it looks better than others: the older beans foam up less.

Try this: after some water has filled the basket, stop the brew and stir the basket grounds to break up the foam.  You might have to do this more than once.  Once the foam has dissipated, let the brew continue normally.  Unfortunately, not all brewers make this "stop and stir" process convenient, and I am unfamiliar with the Bonavita to have a feel for how convenient this is for you.

This may also be partly caused by the drip pattern in the brewer, as others have said.  Stirring part way will help this as well.

Well I have tried some different things.  
Tried different filters - no difference
Tried the room temp pre infusion - no difference
The machine does not lend itself to turning on and off to try pre infusion.
Calibrated the grinder coarser and tried a setting of 28.  At the end of the water delivery the brew basket was 3/4 full of water and it took over 1 minute to drain fully.
Tried a setting of 20.  Basket almost completly full of water and took well over a minute to drain including what seemed like almost stalling at one point.

If I let it drain without me interfering such as swirling the brew basket I get that big v shape.  The really long drain down times are concerning as well.  I am wondering if I am geting a lot of fines.  I also noticed this same slow drain when I used my Tiamo dripper (Kalita clone).  This slow drain has gotten worse lately.

OK I tried it on setting 35 on my Virtuoso and still the same thing.  3/4 of the way full of water and taking well over a minute to drain.  Any ideas.  The coffee is obviously pretty coarse at this point.
