My gas pressure washer is overheating when I run it for 5 minutes. I believe the thermal release valve isn’t working. Anyone know why? Thanks

Can you explain more,
Is the engine overheating or is the pressure pump blowing off. What makes you say the thermal relief valve is not working?
If working with the wand does it still over heat or is it when you just leave the gun closed?

Sounds like the recirculating valve is stuck closed.
