I have a Bosch tumble dryer (14 years old – WTE84102GB/03 ) that started clicking (sounds like relays) after about one minute of use and sometime would start stumbling and then continue on. This became more frequent and one day lights started flashing and it would stop and refuse to start. I got a doner board off ebay and switched across the 4 relays from the doner board thinking they may be the cause but the flashing lights remain. They are the (1st from top) Drying , (2nd from top) Iron Dry and the Anti-crease lights. They flash with a beeping sound and after a while the beeping ends but the flashing remains. This is some type of error code which I can not fathom. It can’t be a clogged condenser as it has its own light (FILTER) that comes on when it needs cleaning. What could be the problem? Does the machine need a reset? It has been off power for 2 weeks and when powered on these flashing lights came on almost immediately. Previously the machine would at least run for a minute before the mood went south.
