After six years of service, our Franke Little Butler hot water dispenser started to leak–from the bottom of the heating tank itself. I should have placed the rimmed baking sheet under the hot water tank a lot earlier.
When the hot water dispenser worked, it was convenient. But, I guess this is no different from a regular hot water heater. It has a set life span and when it fails, it leaks. Except the water heater leaks on the concrete floor of the garage and the hot water tank of the dispenser leaks on the kitchen cabinet. Big difference!
If you look at the reviews on Amazon, many people got less than six years of use from their Franke Little Butler hot water dispenser.
I am not sure if I will replace the Franke Little Butler hot water tank with another one. However, looking around at customer reviews of other brands, I see a lot of similar complaints. When searching for a new hot water dispenser, the keyword is “leak,” as in “[brand x] hot water dispenser leak.” Google that! Nothing stands out at this point.
