Pressure Washer Won't Start - Battery Dead?

Hey all, got a problem with my cordless pressure washer (Greenworks 2000 PSI). It was working fine last week, but now it won't start. Battery is fully charged, but when I pull the trigger, nothing happens. No sound, no nothing. Any ideas?

Check the simple stuff first. Make sure the safety lock isn't engaged, and the water supply is connected and turned on. Some models have a sensor that prevents starting if there's no water flow. Also, check the trigger switch - might be worn out if you've used it a lot.

Could be a dead battery even if it shows charged. I've had that happen - the charger says full but it's actually a bad cell. Try a different battery if you have one. Also, check the connections for corrosion or loose wires.

If it's under warranty, contact Greenworks. But before that, try resetting it: unplug the battery, wait 30 seconds, then reinsert. Sometimes the electronics glitch. Also, if you've got a multimeter, test the battery voltage to make sure it's holding a charge properly.

Thanks guys. I'll try the water flow thing, and I'll test with another battery. If that doesn't work, I'll check the trigger switch. Appreciate the help!
