Alternator valve has jammed – replacement circulation motor will be the only solution. I would suggest that that is not a cost effective repair on this appliance.
I’ll break it to you gently – it’s a Chinese Haier machine, with a badge stuck on it. Use the Search facility, put ‘Haier AND dishwasher’ in for this forum only and see what you’re up against.
There are so many better machines available. Now is the time to stop spending on this one……..
