Icemaker fails after filter replace on Whirlpool

2 year old Whirlpool, ice maker had been working fine until we replaced water filter. Front water dispenser working fine but ice maker not filling. We followed the instructions which say to pulse the water repeatedly for several gallons after replacing filter, in order to flush any water bubbles.

Thanks for any advice.

Hi.

You should check if the ice maker water inlet tube is frozen. It is possible that water was dripping for short time and froze in the tube when you replaced the filter.
Here are the breakdown diagrams and parts list for refrigerator
