Is there any way to clean the scale in the water heater nozzle?

I can teach you a way to remove the scale from the shower head. Generally, white vinegar can be used to remove the scale on the shower head. This is also a common material at home. Remove the shower first, then put it in a small basin filled with white vinegar and soak it for about two hours. After soaking, use a toothbrush. Finally, rinse with clean water.
