KARCHER SC3 STEAM CLEANER REPAIR

An old friend brought in a KARCHER SC3 steam cleaner which had never been used, and he complained that it was it was unable to produces any steam. When I first plugged the unit in I could feel that the heater unit was warming up, but still no steam. It turned out the solenoid operated valve was not allowing water to flow from the water tank to the heater element due to a bad connector on the circuit board. One of my viewers mentioned that the solenoid device I mentioned is actually a solenoid pump, and I think he&probably right since I heard it something making fast clicking noises when I powered it up.
