## How to Clean a Water Heater Thermopile
### What is a Thermopile?
A thermopile is a device that converts heat into electricity. It is typically used in water heaters to measure the temperature of the water. The thermopile is made up of a series of thermocouples, which are devices that generate an electrical current when they are heated.
### Why Clean a Thermopile?
Over time, the thermopile can become dirty or corroded, which can affect its accuracy. A dirty or corroded thermopile may not be able to accurately measure the temperature of the water, which can lead to the water heater not working properly.
### How to Clean a Thermopile
Cleaning a thermopile is a relatively simple process. Here are the steps:
1. Turn off the water heater. This is important for safety reasons.
2. Disconnect the power to the water heater. Again, this is for safety reasons.
3. Remove the thermopile. The thermopile is typically located on the side of the water heater. It is held in place by a few screws.
4. Clean the thermopile. The thermopile can be cleaned with a soft brush or a mild detergent. Be careful not to damage the thermocouples.
5. Reinstall the thermopile. Once the thermopile is clean, reinstall it in the water heater.
6. Turn on the power to the water heater.
7. Turn on the water heater.

If you are having trouble cleaning the thermopile, here are a few troubleshooting tips:
Make sure that the power to the water heater is turned off. This is important for safety reasons.
Use a soft brush or a mild detergent to clean the thermopile. Do not use harsh chemicals or abrasive cleaners.
