I have washing machines Hotpoint Ariston AQ9F 491 X – purchased in France about 6 years ago. Has been working very well but recently the programme timer is not operating correctly. It works fine until the last 16 minutes after which it does not move forward at all and just continues to fill, spin and drain. To stop I have to switch off, wait 10 minutes and then start again from spin only to the end. Can I replace the circuit board of whatever is necessary ??
