We have a 4 yo Bosch Ecologixx 7 tumble dryer this isn't drying well at the moment. After completing basic checks I have noticed the fan on the front bottom right hand corner of the machine is not operating. I have checked to make sure volts are getting to it and they are not. I traced the wires back to the main controller board directly. Whilst there is 230v across 2 of the 3 pins of the plug it's not the two that drive the fan. Conclusion is that the controller board is faulty, before I spend £ 285, does anyone have a better idea?
