SOURCE: How do you clean the unloader valve on a power washer pump?
The unloader valve usually is replaced. I dont know if you can get o-rings for it. But if you want to take it apart, there will be a crown or cap style nut just below the spring. Unscrew it completely and you will be able to remove the spool. There is just a series of o-rings on it.

Hello,
unfortunately these little units have this problem commonly, 9 times out of 10 it will be the plastic head or the plastic valve block on the unit will be cracked and leaking slightly... it builds up pressure then leaks out and tries to build up the pressure again and this just reoccurs over and over...
you can get this repaired but is normally about half the cost of a new unit, if the pressure is still okay i would probably recommend just keep using it until it proper dies...
If you do get this fixed, we have studied into this and believe the main cause of heads cracking is warm water say if your inlet hose is in the sun for a period of time this can cause the water to become quite hot or if the unit sits and water trapped inside the head assy freezes can also cause this.
Hope this helps
Kind Regards
Brad
