I have the above washing m/c which is stopping half way through each wash cycle then starting again about 20 mins later on its own but then will not spin at all, i take it from reading the forum its the brushes that need changing again but i only had them changed about 6 months ago and the 6 months before that too. The prewash cycle also does not work at all. Machine is approx 6 years old. Any comments would be appreciated
