Common Bosch Faults We Repair in Port Coquitlam
Bosch reports problems through alphanumeric EA fault codes (EA 224, EA 338…). These are the faults our technicians diagnose most often on Port Coquitlam service calls:
- EAIgnition Lockout (EA Codes)
EA-series codes (EA 224, EA 227, EA 229) all relate to ignition or flame failure — a failed igniter electrode, a blocked or partially closed gas valve, or low inlet gas pressure. In cooler months, thermal expansion of the flue can shift an exhaust connection enough to dilute combustion air and trigger lockout.
- EA 338Safety Chain Open
Triggered when a safety limit — overheat stat, pressure switch, or low-water cutoff — interrupts the control circuit. Proper diagnosis means systematically testing each safety component rather than just replacing the control board.
- Circulation-Pump Failure
Bosch integrates a variable-speed pump in the Greentherm/Greenstar platforms. Impeller seizure — particularly in units off all summer — is a common autumn call. Symptoms: no heat distribution, unusual pump noise at startup, or an immediate low-flow lockout.
- Flow-Sensor Faults
The DHW flow sensor detects hot-water draw. Lime deposits on the sensor paddle (common in Surrey and Langley water zones) reduce sensitivity, causing delayed or no hot water from an otherwise healthy boiler.
- Heat-Exchanger Scaling
Bosch's lightweight aluminium primary heat exchangers are efficient but need periodic descaling in BC's moderately hard water. Untreated scale cuts thermal transfer, raises outlet temperature, and eventually trips high-limit shutdowns.
