I've just faced today with the issue that the cleaner does move in one direction only. Watched some videos and found that my issue is a unique one. The lever which moves the valve from one direction to another was MISSING inside the gearbox!!!! Unfortunately more than 30 days passed and I was not able to get an exchange from the seller. The quickest way was to order the box from Intex. 11566, Gear Module
Hopefully, my experience will help someone one day.
