Why Does My Greenworks GPW2300 Pressure Go Up and Down?
Exact model: Greenworks GPW2300
Safety: Disconnect the relevant power source and isolate moving, hot or pressurized components before service.
A.
Start with the accessible checks
What this suggests: Repeated pressure cycling can come from intermittent inlet supply, trapped air, clogged tip, a leaking high-pressure joint or pressure-control valve failure.
What to do
- With power disconnected and pressure relieved, restore stable water feed and remove air, clean the correct pressure nozzle and inspect hose/O-rings for leakage.
- Replace a torn hose seal or leaking quick connector with a pressure-rated matching component; never patch high-pressure hose with tape.
- Retest at the same nozzle and constant trigger position.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What to do
- If it still cycles with sound supply and no leakage, a service technician should diagnose unloader/pressure-switch internals rather than overtightening an unknown adjustment screw.
Confirm the repair
Pressure remains steady throughout a controlled spray with no leaks or frequent stop/start pulses.
