And I didnt see and water drainage , plz olz some one help me fix this bar pressure is 1.6 hot water works fine just won't let heating go on ✌💚
I had the F75 error, emptied the water and cleaned this sensor. After the replacement I increased the pressure bht the boiler showed different pressure values, it kept changing until it stabilized and showed a correct pressure. The error code disappeared. The problem is that even after the replacement there is no warm water coming. Do you have an idea what is causing this? Thanks
