Possible Causes

Control board hardware fault, Corrupted firmware, Severe electrical surge damage, Internal sensor bus failure

Safety: Turn OFF power before opening the unit.

Actions:

Perform a full power reset by turning OFF the breaker for 5–10 minutes, then restoring power.
Inspect the control board for visible damage (burn marks, cracked components). If found, replace the main control board.
Check all sensor and element connections to ensure nothing is shorting or overloading the board.
If E19 returns consistently, the control board has likely failed its internal diagnostics and must be replaced.

Board-level repair is not recommended; use an OEM replacement board.
