What Com Error
actually means.
The control you touch and the relay board that switches heat, water and fans talk over a cable. When that conversation drops for 3 seconds, the control shows Com Error. Blodgett's sheet asks for both connections and the cable to be checked for continuity.

What to do when Com Error shows on the commercial applianceKind of codeControls and power
The controller itself is reporting trouble, or the supply behind it is: a display with dead segments, a keypad that stopped responding after steam or degreaser got behind it, relays that stick, stored recipes or cycles that vanished overnight, a blown control fuse, or one leg of a three-phase feed missing so half the heat or the pump is gone. A full power cycle at the breaker, done as the manual describes, clears a passing glitch; a code that returns, a scorched smell or any sign of moisture behind the panel means the breaker stays off, and that is a visit.
