To Next PageTo Next PageWhat does 'Box temperature protection' mean on my Bosch Water Heater?
If the temperature inside the appliance box exceeds 70ºC, it triggers box temperature protection. The error is resolved by a manual reset.
What to do if my Bosch Water Heater has exhaust blockage?
If the fan speed and/or consumption detect a pressure above normal operating conditions on the exhaust, check configuration parameters like AS (altitude), F9 (flue exhaust code), AP (appliance power), etc.
What to do if my Bosch T5600S 12 D 23 shows temperature limiter or thermal fuse opened circuit?
This error occurs if the temperature limiter detects a temperature over 85ºC, or if the thermal fuse contact opens (192ºC) due to overheating and malfunction of the temperature limiter. The error is resolved by manually resetting the system after the temperature limiter cools down and the contact closes again.
Why does my Bosch T5600S 12 D 23 Water Heater display a water flow signal over specified maximum value?
This error occurs when the water flow exceeds 22 l/min. The error is resolved when the water flow is below this value again.
What to do if my Bosch T5600S 12 D 23 Water Heater shows a gas valve wrong connection?
If a safety solenoid from the gas valve is disconnected, the error can be resolved by a manual reset.
What 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.
What does it mean when my Bosch Water Heater 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.
Why does my Bosch T5600S 12 D 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 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 to do if my Bosch T5600S 12 D 23 remote controller removes the error code 5 times continuously within 15mins?
