I have an RF56J9040SR that has just presented this problem 1 month after the warranty has expired !
From reading other forums and watching you tube there are literally HUNDREDS of people reporting this as a recurring problem with this feature across multiple Samsung appliances. Apparently it may be caused (or was in my case) by the ice box feature freezing up so there was actually no ice in the box because the delivery is frozen up. The USA info shows a ‘force defrost’ sequence to assist dealing with this however I cannot find any EU equivalent info at all. We have just emptied the fridge, turned off the power and manually defrosted the box ourselves. Would be great if Samsung would provide this information but they seem surprisingly reluctant.
After thorough defrost and using a usb inspection camera and a hairdryer on cool (there was still ice blocking the inside of the delivery channel) ice maker is back to normal.
Can you advise if there is a 'force defrost' function that would make this process significantly easier?
I have had a look into this and it appears that your appliance is frost-free, which means there is no need to manually defrost your appliance, as this will be carried out automatically as stated on the manual, found here.
I can also see that is not recommendable to use any mechanical devices to accelerate this.
And then the moderator got silent on that hard to answer question that thousands of owners experience here in Europe.
By the way, EU consumer law of 2 year is the minimal time span. Depending on the expected life and price of the purchase. See EU consumer rights.
