TOTO HH20091 is a genuine TOTO electronic spare part known as the DC Controller of Bowl (Bowl Controller PCB). It is used in certain TOTO smart toilets, particularly the CS900/CS901 series.
Part Details
- Part Number: HH20091
- Description: DC Controller of Bowl / Bowl Controller Board
- Type: Electronic control circuit board (PCB)
- Used In: TOTO CS900 and CS901 smart toilet systems.
What Does HH20091 Do?
This controller board manages bowl-related functions, such as:
- Coordinating bowl flushing operations.
- Controlling communication with bowl sensors and actuators.
- Managing pump and water-control components associated with the bowl.
- Monitoring operating signals and safety functions within the toilet system.
When Is It Needed?
Replacement may be required if you experience:
- Flush functions not operating correctly.
- Bowl-related error codes.
- Pump or valve components not responding despite being functional.
- Intermittent operation of automatic toilet features.

Important Notes
- HH20091 is an electronic PCB, not a mechanical spare.
- It is model-specific and generally intended for CS900/CS901 toilets.
- Before replacing the board, technicians usually check the power supply, sensors, wiring harnesses, pump unit, and other related components because similar symptoms can be caused by those parts as well.
If you share your TOTO toilet model number and the fault/error you're seeing, I can help determine whether HH20091 is likely the failed component or if another spare part should be checked first.
