We have a Hotpoint WDPG 9640 Aquarius+ washing machine, purchased in early 2015. Just recently the delay timer has stopped working, but not always. If we set the delay start for 12 or 11 hours – it sits and the clock will not count down. If we set 10 hours it works ok. Any advice would be appreciated regarding whether it’s a fixable/expensive problem or time to get a new one. Thanks, Kev.
