Washing machine extended running time

[SK_13]

We have a Samsung qdrive ecobubble 9kg washing machine bought a few years ago that's really extending running time.

We normally run medium size loads for 53 min cotton cycles. This was approximately being completed in about that time, but as of recent it's running for over 3hrs on that same cycle!!!

We're not adding any heavier weighted loads, just the normal. Our water supply's the same and we're using regular laundry soap.

The clothes come out washed (not shredded or anything). What could be the problem? Electronics?

Has anyone else had a similar issue and how did they get it resolved?

Any help/advise would be appreciated.

Thanks

I was going to say has the water pressure changed but you checked that. Is the washing machine going into spin OK or is it having trouble and deliberating and keeps trying to balance the load? 
Has the water level in the drum changed? - have you seen through the glass door that the water is higher than it used to be when new (if so could need a new water level pressure switch) - Have you pulled out the drain pump filter and see if its nice and clean? - is the machine draining nice and fast as it used to? - could the drain pipe at the back of the machine be pinched?
