Siemens Washing Machine all the spin lights flashing. Help?

Hi Everyone,
Called out to a Siemens washing machine yesterday, and all the spin lights were flashing. What does this fault mean? The Enr is WM14E162GB/06.

I did the reset procedure and it cleared the fault. I selected a program and when it finished filling i selected the spin program, in which it procedure to drain and spin.
However when the customer later did a wash, the same fault came back.
If anyone has an idea what the problem might be i would greatly appreciate it as Xmas is here and i would to have the customer sorted before the big day.
Thanks

P.s .i checked brushed in the motor and they were ok.
