I had the same problem. Occurred in my second-year use. Seat heater stopped working, all else worked fine.
Talked to the Uspa support, they sent me a new seat for replacement.
I did not receive any instructions in the package nor there is any posted on the web.
Uspa support team informed me over the phone that replacement of seat is simple, I disagree. I am comfortable with tools, and engineer by profession, it took me 1-hour to replace the seat. This is all plastic housing and you are opening it for the first time without any instructions, you do not want to break any snap connections.
Anyway, here are my step by step guide:
Disconnect power, disconnect water line from seat connection point. Drain water from the seat by opening the drain valve located in the bottom of the seat rear housing (note that the drain valve on-off is a quarter turn only (use flat-head xxxx driver (-)), after quarter turn you may have to wiggle the drain-valve and carefully pull down the plastic xxxx -valve to drain water, after long use valve most likely is stuck to its seat, do not try to completely remove the valve).
Now you should remove the motor assembly from the rear seat housing.
Turn the seat upside down and look closely for the two screwdriver symbols, (use flathead screwdriver (-)) to pry open the plastic snap lock where pointed. Now carefully pull apart the two other snap locks on the oppose side and wiggle to slide the motor assembly out (this will take some time-don't use force).
Remove the three circuits wires connected to the seat by releasing snap connections, this is simple, just press the connector release and pull out the male connector from its female housing.
To replace the seat you have to unscrew soft-close housing assembly located on the left side of the seat (inside motor housing box). These are two small (phillips-head (+)) screws. Remove the screws and slide the assembly to the left to release the seat.
Now to install your new seat, pass the wires from the right-side hole and slide seat in its place. Insert the soft close assembly piece in the seat on the left side of the frame, this will take some time, do not force as everything you are dealing with is plastic parts. Tighten the two screws in place.
Close the motor housing, make sure while closing that you are not pinching any air release hose or wires.
Slide the new seat back on the toilet housing, reconnect water line, plug in the electric power and you should be good to go.
I just replaced this seat (Jan 2018) and hope that the new seat will last longer and does not have the same problem.
Suggestion for Uspa:
In my opinion, I think this is a manufacturing fault in Uspa-6800. Uspa should prepare a picture-guide for seat replacement and mail that along with the new seat. I also think that a better solution is to replace the whole seat assembly with seat and motor. This is an expensive $500 bidet, and Uspa should offer parts and labor coverage for the duration of its 3year warranty. I have three different bidets in my house, I love Uspa-it is my favorite and performs better than others, however, I will only buy another if a better replacement warranty is offered.
