Hello. Based on the YouTube video I purchased the valve quad water assembly WH13X26637. I successfully removed the old one and installed the new valve. I hooked up the hot water line first, 10 minutes, no leaking, then attached the cold line. After approximately 10 minutes it began to drip. It is not plugged into power. Facing the controls it drips from the far left side. A steady drip, one drop every 3 seconds. I’m stumped. I was sure the new valve would fix the issue. The washer is a GE model GTW680BSJ5WS. Thanks for any help. John

There might have been a small piece of dirt or debris get thru the inlet screen where the hose is attached and get under the seat of the valve. After some time and water flow it might have washed it out. I presume there are screens in the inlet water hose connections. If not there should be. If it comes back again as a problem you might try switching the hose connections for the supply from hot to cold and try that. Did you use new washers in the hose connectors ?

Had a good chat with Wende this morning. Ran a few tests. House main turned off, no leak. Hot water only, no leak. Cold water only, leaks. After speaking with Sally (customer service) I’m being sent another replacement valve. AppliancePartsPro has been very helpful.
