Geez. This is not the way to clean these. Cleaning is not taking it partially apart and wiping it with a rag. All parts should be removed and soaked in water with a mild soap solution. Then carefully dried. You can remove the chrome square from the base and flush it with hot water. You will NEVER get all the bits of the previous solution out of the machine by doing what is shown here. My model even came with small cleaner brushes to get into the holes. Depending on what will be dispensed, do a final flush with water, alcohol, or water followed by a disposable amount of what you will be dispensing.
After using for last 5 days, now suddenly it is showing problem. There is leakage from the nozzle. As I fill the hopper with liquid, It starts draining out through the nozzle. Please help.
