I have that same machine and love it. The light on the on switch burnt out, but there is no need for me to replace.
I use 40 grams of coffee for 20 ounces of water (around what other's have said). Most people think this is too strong. If you cut it down to 35 grams, it it still is good.
I let the the filter res. fill about half way, stir the grinds/water, then insert the pot, allowing more brew time.
