the only error code you see will be the last one so if you see E69 then that is the heating element.put a multimeter across the terminals of the heater and you should get around 29ohms.I suspect you will find it open circuit due to the internal heat fuse blowing possibly due to scale build up on the element.undo the 10mm nut in the centre of the element and carefully prise the element out of the tub.refit new one in reverse
