AEG oko-lavamat 6955 sensorlogic, code F9
I own an AEG 6955 sensorlogic washing machine. This morming I did my laundry, but an error occured at the end of the program: F9. My laundry was ready, there was no water left in the machine (or under it..) and it was as dry as always (I had heard the machine rotate). My manual only mentions F1 and F2 in case of problems. I tried to reset, but that didn't work. I took the power of, checked watersupply and filter, but that didn't word either. I bought this machine in '97, and it worked perfect until now. Is it worth reparing, and what could be the problem?
