Hi y truesteam unit turned om two leds asking to be cleaned . I followed the instructions and cleaned it but when I reasssenbled it I could not turn off the reset light , even after pushing the reset button. So it sits with the reset button led light up , and pluging unpluging it does not seem to help , it just starts the cleaning request process again ? What am I doing wrong if the reset led button does not turn off after pressing the reset button ? Do I have to press it longer? thanks

About three decades ago my parents installed a ducted AutoFlow Humidifier, model 200P. Normally, an appliance that's thirty years old would not be fixable. Not so with the model 200P! An unlimited supply of cheap aftermarket parts is available for this humidifier. Repairing this type of humidifier is incredibly simple. You've got a plastic drum that is turned by a small motor. An evaporator belt is wrapped around the drum. Finally, a simple float valve keeps a tray filled with water. When the drum rotates the belt is kept wet. That's it! The only thing you must not forget to do is frequent cleaning. Every two-to-four weeks is an absolute must, otherwise all sorts of crud will buildup on the belt and in the tray. Here comes the problem. The float valve normally lasts for several years. They have an adjustable arm, combined with a slot in the box which allows you to control how much water will flow into the tray. About two winters ago I purchased a couple of new float valves for my parents. For reasons I cannot explain, they work fine for a few weeks and then you start to notice water dripping from the overflow tube in the tray. Adjusting the valve becomes a hopeless task. No matter how much you fiddle with the darn thing, nothing seems to work. Because they are cheap, I've installed four float valve in the last two years. The design of these float valves is very simple. Almost too simple, but they worked fine for 28 years! If you have allergies and are living in a house with forced hot air you very much need a working humidifier. I know there are other types of ducted humidifiers. Several years ago, I removed the chrome plated box from the duct, cleaned off a little rust and sprayed it with some Rustoleum. It looks new, and the box is solidly screwed and caulked against a large hole in the duct. Except for continuously replacing the float valves, I don't know what else to do. I have a decent shop, so if someone has a suggestion about how I could modify one of these valves to make it more reliable, that would be a real blessing for my parents. If not, maybe there is a better quality float valve that would fit this model humidifier. Any suggestions would be greatly appreciated!
