Siemens WK14D41GB/07 Error 1

Hi all,

I hope everyone is doing well. Was wondering if one of you can point me in the direction of the fault likely to be on this one as I need to try and go armed with parts if possible. Its coming up with error 1 at the first 2 mins of the cycle starting. Not sure if the fault codes for this model are the same as the other siemens integrated washer dryers as I cant see these listed.

Any help greatly received.

Thanks in advance
Mark
