1. If the motor runs but soap is not dispensing, first check the soap reservoir to make sure the unit is full of liquid soap.
2. If the reservoir does have soap and is freshly filled, note that it may take up to five activations before the pump brings the soap to the nozzle and dispenses soap. Place your hand repeatedly under the nozzle to see if soap dispenses after the fifth activation.
3. If the reservoir does contain soap but no soap dispenses after repeated activations, then hardened soap particles may be clogging the dispensing tube. Pour the remaining soap out of the unit. Fill the reservoir with very warm (but not boiling hot) water. Gently swirl the unit for a minute or two then pour out the warm water. Repeat this as necessary until water is not soapy when poured out. Fill the reservoir again with warm water, and then activate it by placing your hand under the dispenser (be careful that the water is not too hot). Activate repeatedly to get the warm water pumped up the tube to break the clog.
4. Soaps with fragrance particles or exfoliating scrubs are not recommended as the particles can clog the dispensing tube. Thick gel-type soaps are also not recommended.
