To Next PageTo Next PageWhat causes the 'Wrong gas type' error in my Bosch Water Heater, and how do I fix it?
If an output higher than expected is obtained, it indicates the wrong gas type is being used. The error is resolved by performing a manual reset.
Why does my Bosch WTD 15-4 AME 23 show an error related to the temperature limiter or thermal fuse?
If the temperature limiter detects a temperature over 85ºC, it causes the temperature limiter or thermal fuse to open the circuit. This error is resolved by manually resetting the system after the temperature limiter cools down and the contact closes again.
What does it mean when my Bosch WTD 15-4 AME 23 displays MCU RAM DC (micro controller) internal error?
Check if the voltage is too low (less than 70V AC). This error is resolved by a manual reset. If the voltage is okay and the error persists, replace the control unit.
What to do if my Bosch WTD 15-4 AME 23 displays MCU registration DC (micro controller) error?
This error is resolved by a manual reset. If the error persists, replace control unit.
What to do if my Bosch WTD 15-4 AME 23 displays MCU ROM (micro controller) error?
This error is resolved by a manual reset. If the error persists, replace control unit.
Why does my Bosch WTD 15-4 AME 23 Water Heater show over-temperature detected?
The control unit might be detecting an outlet water temperature exceeding 85ºC. This error is resolved by a manual reset.
What to do if my Bosch WTD 15-4 AME 23 Water Heater displays an MCU PC (micro controller) instruction error?
This error can be resolved by a manual reset. If the error continues, consider replacing the control unit.
What to do if my Bosch Water Heater displays a solenoid valve drive circuit error?
This error is resolved by a manual reset. If the error persists, replace the control unit.
What to do if my Bosch Water Heater displays an internal checking failure?
This error is resolved by a manual reset. If the error persists, replace the control unit.
What does it mean when my Bosch Water Heater displays a box temperature protection error?
This error indicates that the temperature inside the appliance box is over 70ºC. A manual reset is required to resolve the error.
