The disclosure reveals a system for detecting moisture or water in a particular location. The system may incorporate a moisture detector having a control module connected to an appliance, a moisture detection circuit connected to the control module, and a voltage source connected to the moisture detection circuit and to the control module. The voltage source and the moisture detection circuit may provide voltage levels to the control module when the moisture detection circuit detects dry or wet conditions, or conditions between those conditions. A voltage level to the control module may indicate whether the appliance, such as a water heater, a washing machine, or a dish washer, has a leak. If the leak is deemed by a voltage level from the circuit to be worthy of concern, then a display, an alarm, message, or other notice mechanism may indicate an issue or what action needs to be taken.
