My washer dryer works perfectly on washing cycles however when I try to use the dryer it will either start to heat up and then trip the RCD in the fuse box after a few minutes or it carries out the whole cycle but the clothes come out stone cold and wet.
Is this likely to be a faulty drying element or could it just be the connection to the element? Is the element easy to locate and replace?
elements normally work or they dont from what you say it does sound more like a bad connection the makes sometimes. if this bad connection sparks then it can blow an rcd
element is in a box at the top of the machine. check all the thermostats on this box for signs of loose connections or burning
