20 Most Recent Honda Karcher G4000RH Pressure Washer Questions & Answers

The rope may be bound up in the recoil. Take the recoil cover off(the piece where the pull rope goes into) and try to pull the rope with the housing off. If it pulls freely try turning the engine by hand, you may want to remove the spark plug to release the compression. If the unit will not turn over,then the pressure pump may have failed. Best of luck.

where is the unloader valve locaed on a Briggs Stratton pressure washer?

Honda Karcher... | Answered on Oct 03, 2009

Unloader valve is the most likely suspect here.
Remove and clean with penetrating oil then reinstall.

Also add some LIGHT oil into your supply hose via a small funnel. 3-in-1 household oil or power steering fluid lubricate the valve and pump quite well. Three or four treatments of a couple ounces each will usually make the pump happy again. If this unit has an OIL-FILLED pump on it you can expect good results. If it runs an OIL-LESS pump it is only rated for about 100 total hours of life!
Hope this helps.

it sounds like your unloading valve is crudded up with mineral deposits and stuck in a partway open state. look for a plastic cover with a silver snap on top; pry off the silver snap and lift off the plastic cover; next remove the two screws on the top plate then pull out the piston inside - if unable to lift out, start unit and watch it pop out - coat piston with lithium grease and reinstall - it will work great

did you pour all of the old gas out before you started to use it. Sometimes condensation builds up in gas tank when stored. You need to dump old gas an put in new gas.

Per owners manual... WATER PUMP OIL IMPORTANT: If oil is white or foaming, water is in the oil reservoir. Change oil.NOTE: Water in oil occurs as a result of spray or condensation. Milky oil is not indicative of a pump malfunction.

it needs to be taken apart to see whats broken inside

Check for continuity on the ignition module kill wire to engine block. Without the oil sentry there should be a single black wire from the ignition module to the ignition switch. This wire goes to the ignition switch and when in the OFF position connects to engine frame to disable spark.

You could disconnect the kill wire at the ignition module and then check for spark. If spark then the kill wire or switch is connected to block (short) or bad switch.
