Siemens Washing Machine Cycle Stuck On 1 Minute To Go

Hi Team,

Hopefully posted in the right forum and first post for now!

I have a Siemens washing machine WM14S794GB / 08 and it continues to run with 1 minute to go on the display.

I have cleaned all pipes, pump filters, etc and cannot find any blockages.

If I run the machine on a quick 15minute (30 degrees) programme, irrespective of spin speed then the cycle completed without any issues at all.

The problem only occurs if I choose a programme other than the quick 15 minute programme...

I have checked the forum and have read posts on heater elements, pressure switches but cannot understand how these could be faulty if the 15 minute cycle completes?

Not sure if I an applying the right logic to this but would appreciate any support or guidance as machine came out of extended warranty 5 months ago!

Thanks in advance.
