I think I have an idea what the problem is, but would like another opinion please. The machine starts and fills as normal, but after about 35-40 mins when it gets to the drain part of the cycle it stops, although the machine sounds like it is either filling or draining, but it is doing neither.
I have taken all drainage hoses off and cleaned them and checked for any obstructions and it makes no difference. Also, after about 5 mins of the program getting 'stuck' all of the program display lights start to flash.
Any ideas please?

Thanks Andy, but I have tried that. I have removed both the grey and the black hoses to the pump as well as the electrical connector (yesterday). There is no blockage along either hose. I also stripped the pump into its two piece and removed the impeller. There was some sludge in there so I thoiught a clean out of that would solve the problem, alas no.
On further analysis it seems that due to the machine not draining the old water from the first part of the cycle is causing the machine to completely stop and not continue into the rinse cycle. I think I have resigned myself to the fact it needs a replacement pump, which fortunately I have located for around £40 inc delivery. Unless of course another response solves the issue before I purchase!

blocked pump filter. remove plinth and unscrew filter, remove blockage. assuming the drum has water in it , try dropping the grey drain hose into a bucket and drain down first before opening filter. hope you have lots of towels !
