This error is resolved by a manual reset.
Why does my Bosch Water Heater use the wrong gas type?
If the appliance obtains an output higher than expected, it indicates the wrong gas type is being used. A manual reset should resolve this error.
What does it mean when my Bosch WTD 15-4 AME 23 displays an ionization error?
If ionization is detected without heat demand, it results in an error. Perform a manual reset to resolve it.
What to do if my Bosch WTD 15-4 AME 23 Water Heater shows leakage on gas valve?
If ionization is present for more than 4 seconds, it indicates a leakage on the gas valve. Resetting the system manually should resolve this issue.
Why does my Bosch WTD 15-4 AME 23 Water Heater have ionization loss?
This issue occurs when the ionization signal is lost 3 consecutive times. A manual reset should resolve the error.
What to do if my Bosch WTD 15-4 AME 23 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.
Why does my Bosch WTD 15-4 AME 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 Water Heater 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.
What to do if my Bosch WTD 15-4 AME 23 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.
