William Lindley for Model Number MAV7551 I have only cold water - no hot. On warm setting no water at all flows. I switched the inlet lines - on cold water setting hot water flows. On hot water setting and warm, no water flows.
Answer Hi William, most likely you need a new water valve but you're going to need to check your serial number so you know which one to order. There were two different valves used on your model due to a change by the manufacturer. If your serial number starts "10" through "18", order part# W10821146. If your serial number starts with "19" or higher, order part# WP22004333. If you're unsure please call us and someone will be glad to help you figure it out. Thanks! Read More...
