Do you happen to have a meter to test with? Also, is your heater indicator lit up on the topside?
OK, if the heater light is on, with no error codes showing then we should have 240 volts when touching both heater terminals at the same time with meter probes. If we don't have 240 volts there, then you've got a bad circuit board. Are you able to test that at some point?
