Question

What's wrong if the pilot light will light, but when I turn on the heater it goes out?

Community Answer

Most likely it is due to a bad thermocouple, you'll need to replace it. It is a very cheap part to replace.

Question

Can I use paper to start a water heater with an igniter, and bypass using the igniter?

Community Answer

No. The system is designed to not work at all if any component fails a checksum.

Replace it. It's not a serviceable part, and should never be tampered with.

Why does my pilot light go out when I release the button?

Community Answer

Because the button is connected to the light and turns off when you turn it a certain way.

Question

Does the bottom of the water heater need to be dry before I use it again?

Community Answer

Try using a towel to wipe the bottom of the water heater before attempting to start it. You can use a stick to get the towel into hard-to-reach places. The water heater is most likely safe to use as long as the water is not dripping on any components. If you are concerned about safety, consider getting a plumber to do an inspection.
