Thank you for your question. The valve cartridge assembly in the valve body maybe the issue. Turn your water off at the shut off valve. Remove your handle and unscrew your bonnet nut. Pull the cartridge straight out. When the cartridge is out of the valve body, turn the cartridge around 180 degrees. Reinstall the valve cartridge and reinstall all parts. This will now allow cold water to be on first, and then hot water.
