Barely any coffee rises to upper chamber after cooking

Probably water level sensor bad or damaged. Possibly connections to it are loose or corroded.

Yes it could very well be the fan. When sitting still the fan in the only thing that can create air movement thru the radiator to cool it.

Try turning down the temperature. Also make sure there is no coffee left around the edge of the joining surface. This worked for me.

Lets do this, remove the bean hopper, and make sure there are no beans in the burr chamber. Then looking down at the collar with the numbers back up screw if there is one on it. Now if memory serves me right clockwise is coarse and counter is fine. Look down in the burr chamber, notice the nut in the middle, turn it with your fingers that will move the bottom burr, if burr turns freely we will move on if not plug in grinder and let it grind out remaining beans. With beans gone unplug grinder, then turn collar towards fine until you cannot go no more, now try turning nut it will be hard if not impossible to move, turn collar towards coarse until you can barely move bottom burr with fingers, you will hear and feel the burrs touching, that will be our bottom setting. Now pick a spot on the grinder you can use the small notch in the middle, count out 16 notches towards coarse and turn collar to that point. Use the notches around the collar not the ones on the top next to the numbers. Your grind should be almost perfect, depending on blend and machine you might have to adjust 1 notch to the left or right after testing.

HI try finding cooks on google and send them the serial number they might exchange it for you

Problem with oven sensor or control board (ERC). Oven sensor at room temperature should have resistance about 1080 Ohms, and it rises with temp rise.

OH GOD... OPLZ SAV HIM

Check the coffee dregs are they wet? Or are they even there?
If there are no dregs then the grinder chamber is clogged and needs to be cleared out, remove the brew unit and you can gain access to the chamber on the left. Clean the chamber.

Easiest way to set the grind on the super jolly is to remove the beans, turn towards fine until you can barely move the middle stem in the grind chamber, then turn towards course about 12-14 notches on the grinding adjuster(not numbers but notches between numbers). If you still cannot get a fine grind and it is not a brand new grinder replace burrs.

Sounds like there maybe something stuck underneath the float, The float is the round coffee cup like thing in the bottom of the dishwasher That happend to me and something was just stuck not letting the float rise. I sure hope this help you out I just seen you thread and thought I would try to help you out Hope it does
