I agree, a bit of water is normal when you first start steaming, also the heater coming on is to keep the steam going. Both things are normal. Check the Boiler water lever probe as suggested to see how clean your boiler is. And go to the link given as it is very good and has videos. You might want to start using softened water, at least to cut down your tap water hardness.
Make sure you are not over filling the tank and getting drips that way. Check the water spots by drying the machine and then putting dark paper under it and checking for where the drips come from.
Buying advice: GRINDER GRINDER GRINDER. Don't cheap out on the grinder.
