yes...check the check valve. A one-way directional valve, this part is also known as a DUMP valve. It opens when too much pressure builds in the hand wand (when not spraying water) in order to protect the pump, by returning the high pressure to its source reservoir. I suspect the DUMP valve is stuck in open condition (or nearly open).
