I have a Generac pressure washer, model #01450-0, with a Honda 5hp motor. The motor runs fine, but the pressure hose pulsates as if the pump is intermittently making pressure, and the pressure out of the sprayer is about half of what it should be. A friend suggested replacing the seals in the unloader. I bought an unloader kit, replaced everything and it still runs the same. It will build a small amount of pressure, spray for a few seconds, then the pressure dropps to almost nothing. Any help ap

Dishwasher fills with hot water. Float OK - water feed stops when full. Motor humms but no water spray (in all opperating modes). Cancel selection (with cancel button) and close the door. The water drains then the unit shuts off. Water feed OK. Drain Cycle OK. Looks like spray pump hung but do not know. Cannot find a reset button (as with disposal) or way to free hung pump motor. I did see glass pieces in the drain. Possibly a small piece hanging the motor.

I have a Briggs & Stratton gas power washer. This is the 1st time this year that I have used it. I put in fresh gas, hooked up the water supply. The engine started and then quickly stopped. I had to release the water pressure in the hose before I could pull start the engine. The only way to keep the engine running is to hold down the spray nozzle trigger. Once that is released the pressure in the hose builds up and the engine stops.

Noticed dishes on top shelf not entirely clean. Ran machine empty and opened many times during wash. Noticed that Lower Spray Arm works as expected, but Middle Spray Arm turns only 1/8 or less, then Lower Arm spins again. Schematic with Use and Care manual just says pump motor switches from one to the other in certain cycles, but I don't see this happening. Looked for obstructions to water flow and pressure seems normal. Is control for this function part of the pump, or in the control panel?
