Overview

The DWM4020G is a wall-mount cold water electric pressure washer rated 2000 PSI at 4.0 GPM, driven by a Marathon Electric 6.0 HP motor on 230V single-phase power. A heavy-duty GP General Pump industrial pump runs direct-drive, and the whole unit hangs on a corrosion-resistant aircraft-grade aluminum frame — off the floor, out of the work area, and always plumbed and ready. It ships with a gun-wand assembly, 50-foot high-pressure hose with quick connects, 10% chemical injector, and five color-coded QC nozzles, with a 12-foot power cord ready to hardwire. Built for everyday use in wash bays, shops, and equipment yards; assembled in the USA. An Auto-Start/Stop version (DWM4020G/AUTO) is available.

Frequently asked questions

It includes a heavy-duty gun-wand assembly with quick-connect couplers, a 50-foot non-marking high-pressure hose, a 10% chemical injector, four color-coded stainless QC spray nozzles, one brass QC chemical nozzle, and a stainless inlet filter with external bypass. The 12-foot power cord comes ready to hardwire.

No — it runs on 230V single-phase power at 26 amps and ships with a 12-foot cord ready to hardwire. Plan on a dedicated 230V circuit installed by an electrician rather than a standard 120V wall outlet.

Yes — part number DWM4020G/AUTO adds Auto-Start/Stop, which shuts the unit off when the gun is released and restarts it when you pull the trigger. That saves run time, reduces wear on the pump and motor, and extends service life.

A wall mount keeps the pressure washer off the ground and out of the work area, permanently plumbed and wired in one spot so it's always ready to use. It's the right setup for a fixed wash bay, shop, or garage where the machine doesn't need to travel.
