I fixed a leak in my water maun in the crawl space. After that I let the faucets run for few mins to drain any air out. But since then my washing machine is showing error code nf. I got a washing machine technician who unpluged the water hose and told no water coming. He said it is a plumbing issue. All my faucets are working fine and there is no sign of any water leak anywhere. Can you help?
