The TOTO HH55004N spare part is a Valve Solenoid Unit (Valve Electromagnetic Unit) used in TOTO automatic sensor urinals, particularly the US800CK / US820 series. Its function is to open and close the water flow electronically when the controller receives a signal from the infrared sensor.
Uses of HH55004N
- Controls flushing water flow in sensor-operated urinals.
- Receives electrical activation from the controller board (such as HH54004S).
- Opens the flush valve during a flush cycle and closes it afterward.
- Helps regulate automatic flushing without manual operation.
Related Parts
- HH54004S – Electronic controller module.
- HH55004N – Solenoid valve unit.
Common Fault Symptoms
If the HH55004N is defective, you may see:
- No flush even when the sensor detects a user.
- Continuous water flow or leaking flush valve.
- Intermittent flushing.
- Clicking sound from the controller but no water discharge.
If you can provide the exact urinal model (for example, US800CK, UFS800CK, or US820), I can help with the wiring diagram, troubleshooting procedure, and compatibility of HH55004N with HH54004S.
