The last time I used the pressure washer was running fine. A few minutes later I tried to start it up and could barely turn it over. I removed the recoil and could turn it a little easier backwards. The motor is a Honda GC190 on a karcher pressure washer and has 20 -30 hours of running time. Thanks Clint

Northstar Hot Water Pressure Washer (model #157322) While using the pressure washer the safety relief valve activated venting steam and hot water from it...

This pressure washer is approx 18 months old!
