    Promax FSB HE - central heating not working but hot water still fine.

    If I turn on the hot water, the boiler starts up first time and works fine, but it is completely unresponsive to me turning on the central heating. It doesn't make any sounds, no flashing lights (just power on, and flame off like it's still on standby). Is there anything obvious I should...

    Plastic gas pipe to boiler!

    Not technically a disaster, but felt this was the most appropriate section of the forum. Just a story from a now retired plumber in my family. A long time ago, a plumber in my extended family (now retired) got a call from someone saying they could smell gas in their home. When he got there, he...

    Vaillant Ecotec 937 plus - Flu fan constantly on, LCD dead, No heating or hot water - Common fault or not?

    Had a short power cut earlier and when the power came back on, it looks like my Vaillant Ecotec 937 plus boiler died. My educated guess is either when the power went out or when the power came back on, the PCB on my boiler died, as now it is completely unresponsive (LCD dead, no heating or hot...

    Hot and cold bath tap

    our boiler pressure is dropping to 0 even after having the blender valve replaced, paid £80. Maybe 2weeks ago. This was when our pressure was at 0 and only cold water was coming out. Now my water is going hot and cold every 15/20 seconds from the bath tap. Any ideas only moved in a month ago

    Hello everyone. I've recently moved into a flat and it has a vokera boiler. We've noticed the smell of gas whenever we switch on water, and I've noticed it from another flat as well.

    Boiler power switch melted again

    This is the second time this has happened in 10 years, I believe caused by me using the immersion heater today. Can you identify the switch for me so I can buy a new one. My best guess is a 45w cooker switch: https://www.toolstation.com/axiom-45a-dp-cooker-switch/p81324

    C1 Fan Error on Worcester Bosch 28 HE Boiler

    The C1 code is showing (error with fan) after I first first hear brief whirring-ticking, like the fan motor is trying to get going, so possibly more likely the motor as the display is normal until I attempt to run the boiler? I realise this is possibly down to a faulty PCB, which could have...
