What Communication Error
actually means.
The touchscreen TQ3 runs firmware that can be updated from a USB drive. When its control parts lose communication, the screen shows Communication Error. Hatco's first step is to download current software from its website to a USB drive and follow the firmware update procedure in the manual; a new electronic control is the fallback.

What to do when Communication 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.

What not to do
Communication Error is not about heat or the probe; the toaster may heat normally before it stops. It is different from Touch Panel Error, which concerns the screen surface.
