Our platinum fountain pump finally failed after 10+ years of good service.. Over the years it became necessary to fiddle with the pump to get it to start but it would then run until the next cleaning. This time it would not start so I went online to look to buy a new one and ran into the information that the pump face is removable. When removed, the impeller was totally contaminated. I used a soft tooth brush to clean it and the guide cover and reassembled it. It now runs like new. Rather than complaining, people should clean the pump at least annually. This has been a really good product and is highly recommended.
