What Is A Vaillant Boiler F75 Error Code?
Vaillant is a brand with a range of tank-less combi boilers, many (but not all) are called Ecotec Plus or Ecotec Pro with a model number at the end. Just like a computer failing to come on, your boiler has internal components that can fail – the F75 fault code refers to an error in the mechanics of the boiler that has caused it to go into a safety shutdown state.
So, what is this error all about? It happens when the timer activates the system or you press the button to switch it on but nothing happens. There are several reasons for this. It might be that the low water pressure switch is faulty, or it might just be that the pump didn’t kick in or do its job correctly. Regardless, if you are experiencing this error, the worst thing that you can do is to fix the problem yourself – you would likely be breaking the law if you tried (unless you’re qualified to do so). What’s more, the error is highlighting a problem with the boiler that needs attention – it would be foolish to try to override any boiler safety mechanism. There’s a reason why we have heating engineers – they are experts at identifying problems in your boiler and fixing them.
