DIAGNOSIS Yeah, this one's common. The 'Slow Cook' mode on the Crock-Pot Express runs at a lower wattage than traditional slow cookers. It also uses a different heating pattern that can feel underwhelming, especially if you're not starting with hot liquid.
FIX For best results, use the 'Sauté' function first to bring your liquids and ingredients to a simmer *before* switching to 'Slow Cook'. This gives it a head start. Also, keep the lid on the entire time—lifting it causes significant heat loss.
IF THAT DIDN'T WORK Consider using a pressure cooking program instead for similar 'set-and-forget' meals. The 'Stew' or 'Meat' settings with adjusted times often work better than the dedicated Slow Cook mode for many users.
HEADS UP The 'Slow Cook' mode will not bring a pot of cold ingredients to a boil. It's designed to maintain a simmer, so starting with everything already hot is key for this machine.
