Check the nozzles to see if they're clogged. Just stick a pin in the opening to clear any cooked fluid. You may need to remove it - most are simple threaded fittings. If that doesn't do it, you'll need to disassemble the machine and open up the heater. Not difficult, just tedious. And avoid using cheap fluids - lots of problems come from bad fog juice.
