It sounds to me that either your PSU can't supply the heater current, or there is a bad connection between the PSU and the Duet. It's also possible but less likely that there is a bad joint on the Duet, either between the VIN terminal block and the PCB, or between the 7.5A fuse holder (assuming it is a Duet 2) and the PCB.

@Veti They are buttons that give a 3.3V current when pressed, 0V when not pressed.

@aidar Ah yeah both fuses are blown. I'll try later with new ones
