Hi there AskoMiele. I,m sorry to say, that the timer in these old Miele machines cannot be opened. Also the problem you mention here are are quiet known of. I have repaired some Mieles with this problem. The only thing you can do is find a replacment. I dont think it will work with the 5402 timer. But if you find an w 429-433 it might work.
