Last time I tried to use the washer I had had to keep the trigger pulled on the gun other wise it would build up to much pressure between the pump and the gun and would stall the motor. Also if it does stall the motor I have to undo the hose from the pump to release the pressure because theres so much at the gun you can't squezze the trigger. is this a gun problem or the pump. the washer is like brand new and has always been stored indoors including in the winter.
