Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

An E25 error is an "outlet water temp rose too quickly" error. This could be cause by air in the boiler loop or a pump that isn't working properly or possibly an issue with the sensor. Unfortunately none of these causes can be resolved by a quick fix or a simple adjustment. You're probably going to need to call a plumber to fix this.
