Thank you for contacting Biobidet Support.
I am sorry to hear your BB600 has cold water only.
Thank you for providing the troubleshooting steps you have already taken.
Make sure the bidet is not on Economy mode or the water temp is in the "off" setting.
If these things have been checked, please contact us for service repairs at email@example.com
