Hi guys. I wonder if you could give me some advice please. My daughter has just bought a Bosch Condenser dryer Model no WTW863S1GB from John Lewis.Half way through the drying cycle CLn shows on the display. This alternates with the time remaining. She checks the lint filter and water reservoir but they are clear..Is this a fault? It still dries the load and CLn does go off eventually.She wonders if she needs to contact the store to get an engineer out? Thanks in advance.
