If your Lochinvar boiler is showing error codes, or blinking lights, then you probably need to take your unit to a plumber for service. There are several possible causes of this problem, and some are simple enough to solve yourself. Here are some of the most common causes and how to troubleshoot them.

A loose jumper or a device wired across a gas pressure switch terminal may cause the problem. A blocked drain switch is another common cause of this error, which indicates excessive condensate build-up.
