ok - I don't have that model but sympathise - are you using dried milk powder in your recipes ?- lots of manuals recommend this and it gives a horrible crust - I would also take the loaf straight out of the machine and put onto a rack until it cools - will look out the 2 recipes I use and will post them later.
if your wtill within warenty then the panasonic is fab!!
with the one you've got, is there a possibility that your yeast is old? as this can turn out crumpet-esqe bread? somethings have to stay the same e.g.flour yeast water but things like sugar you can cut down...have a fiddle with it...used to have a morphy richards 1 but cant for the life of me remember anything about its name i just know it took alot of fiddling to get it right!
ooh really good strong bread flour is really good to-remember that was a must to!!
