Perform a cold restart
Sometimes a “cold restart” clears the fault. When a cold restart is recommended in one of the Solutions below, do the
following:
1. Power OFF the machine.
2. Wait 30 seconds or until the red LED near the top of the DSP board blinks once.
3. Power ON the machine.

Each table below describes a fault category and suggests solutions for each fault code. Several of the fault solutions

If a fault occurs while using a generator, turning the power switch quickly to OFF and then
to ON again (sometimes called a “quick reset”) may not clear the fault. Instead, see
Perform a cold restart on page 131.
