Some of the ground coffee clumps up in the grinding area instead of going into the brew basket. This is a nuisance to clean and it must be clean and dry to make another pot. The grinder is preset to a fairly coarse grind requiring the use of more coffee beans to get the stronger flavour you may want.  Steam from brewing collects in the grinder.  Because of the need to wash and dry thoroughly all the grinder parts, we have resorted to pre grinding our coffee. We place it in the brew basket,  bypassing the grinder. This makes an OK cup of coffee, but defeats the purpose of having a built in grinder.  We do not recommend this particular coffee maker.
