Thank you for contacting Biobidet Support!
I am very sorry to hear your USPA 6800 is making a loud noise!
Unfortunatly there is not a whole lot of troubleshooting involved with this problem. You can try one thing for but highly unlikey this will "solve" the problem.
Turn off water to shut off valve.
Drain water tank
Leave overnight if possible
In morning try again
If you are still experiencing this problem after this, please submit your request for repairs at email@example.com
