Caleb M Philadelphia , PA November 14, 2014 Appliance: Model VIKING VCSF036DSS Faulty water inlet valve causing water flow to chatter then stop Whirlpool part #670056154 is IDENTICAL to Viking part #PS40027. Viking wants $277 for a $60 whirlpool part, it is the same part. Switched easily, works flawlessly. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
