Overview

The DWM4020GAUTO is a wall-mount cold water electric pressure washer rated 2000 PSI at 4.0 GPM, powered by a 6.0 HP Marathon Electric motor on 230V single-phase power with a direct-drive GP General Pump. The auto start/stop feature shuts the unit off when you release the gun trigger and restarts it when you squeeze — cutting run time, wear, and noise in everyday use. The corrosion-resistant aircraft-grade aluminum frame mounts up off the floor, keeping the machine out of the work area and ready to go. A 12-foot cord comes ready to hardwire, and it ships complete with a 50-foot non-marking quick-connect hose, gun-wand assembly, chemical injector, and nozzle set. Built and assembled in the USA for shops, wash bays, and facilities that clean daily.

Frequently asked questions

Auto start/stop shuts the motor off automatically when you release the gun trigger and restarts it the moment you squeeze again. This cuts idle run time, reduces wear on the pump and motor, and extends the machine's service life compared with a unit that runs continuously between tasks.

It requires 230V single-phase power and comes with a 12-foot cord ready to be hardwired — it does not plug into a standard 120V household outlet. Have a qualified electrician wire it to a properly rated dedicated circuit.

It includes a 50-foot non-marking high-pressure hose with quick connects, a heavy-duty gun-wand assembly with QC couplers, a 10% chemical injector, four color-coded stainless quick-connect spray nozzles, one brass chemical nozzle, and a stainless inlet filter with external bypass.

No — this is a cold water pressure washer; it has no burner or heating coil. At 2000 PSI and 4.0 GPM it handles everyday cold-water cleaning like equipment washdown, wash bays, and flatwork. If you need heat for grease or oil, look at a hot water unit instead.
