Soap and Hose

We bought the unit in August 2014, but we just used it in our home today. We would like what is the best soap to use, and most of all, the plastic hose going into the soap container is very loose. Is there a stopper to cover the hose, so the soap doesn't blow out from the hole? please advise.

Power washer-safe detergents are the only detergents that should be utilized with Generac residential grade power washers. Also, please note that any acidic solutions, (including bleach, acids, or citrus scented soaps) should be utilized and are not recommended for use. Considering this, we as the unit’s manufacturer can recommend utilizing a mild (non-citrus) dish soap, or liquid auto soap, when utilizing your residential power washer’s detergent nozzle. Any damage incurred through the use of alternative cleaning agents would void the product’s warranty.

Lastly, please note that we do not manufacture any stoppers or restrictive parts for detergent use. To ensure that your unit is able to optimally perform when utilizing detergent, be sure to insert the filter on the end of the siphoning tube through the hole in the chemical tank cap, and make sure the siphoning tube remains fully submerged in the detergent. All of the aforementioned information can also be located in your product’s owner’s manual. To locate your unit’s documentation online, please use the product’s model or serial number for searching purposes via the following link: http://www.generac.com/service-supp....

Question

Why does my Onewash shut down after running only 10 minutes?

I have a one year old OneWash with maybe 4 hours of operation. Starts up OK but after running for 10 minutes or so it cuts off.. Starts up again OK but only runs for a minute and then cuts off again. Then on for another minute before stopping again. Water supply, gas and oil supply OK. Almost seems like it gets too hot and shuts down. What came I do to keep it running?

We are sorry to learn of the issues that you are currently experiencing with your residential grade power washer. In addition to the checks that you have made, we would also recommend checking whether or not the unit's spark plug is appropriately wired or requires replacing. Additionally, if the unit ever bogs down or shuts down during operation, we would recommend checking the unit's air cleaner and replacing it if it is dirty. Also, if the fuel is stale, or if there is water in the fuel, we would recommend draining the unit and re-filling the washer with fresh fuel. Lastly, if your unit is filled with an excessively rich fuel mixture, or if all recommended checks can be performed and issues persist thereafter, we would recommend contacting an independent authorized service provider for any required servicing. To locate an independent authorized service provider closest to you for diagnostic work, please use your postal code for searching purposes via the following link: http://www.generac.com/dealer-locat....

Per the unit's spec sheet, Generac's OneWash residential grade power washer, model number 6602, comes with a 30' high pressure hose. Additionally, per the unit’s owner’s manual, the garden hose connected to the unit should have a maximum supply of 50 feet provided; this is to ensure that the appropriate amount of pressure runs through the hose provided to the unit. We do not have any recommendations on how to expand passed this specified length, and any damage incurred to the unit when utilizing the unit in a manner that is not recommended will not be covered under the product’s warranty. Moreover, we do not have any extension hoses for the high pressure hose that connect to the unit’s gun. If you have any additional inquiries regarding a particular unit or associated accessory, please contact us directly at 888-GENERAC (436-3722).

Please note that Generac offers a 2nd Story Nozzle Kit, which includes a pink high pressure soap nozzle and blue high pressure rinse nozzle; both of these nozzles are suitable for cleaning upper floors of a standing home or building. Otherwise, as stated in the unit's owner's manual, model number 6602 features a drain-able detergent tank used to hold power washer safe detergents to be siphoned into the unit's low pressure stream; we would not recommend attempting to alter or modify the siphoning system as doing so would void the product's warranty. To inquire about the pricing and availability of particular accessories, we would recommend contacting a local independent authorized dealer in your local area.

Although not recommended by the manufacturer, I dismantled the gun and determined that the ball seat had unseated itself somehow and was preventing the valve from closing properly. Once the Seat was positioned correctly the valve fully closes and the washer operates without using excessive water. The staff suggestion to contact a distributor would have resulted in them selling me another gun.

Question

Why on initial oil fill it takes less than 20oz

Filling engine with oil for the first time.
Using the provided 20oz oil bottle and HANDY funnel (thanks for that) it over filled and ran out all over ground.

WARNING TO OTHER NEW OWNERS.

What a mess. I would say it only needed about 16 oz after cleaning up mess and then tipping sideways to get Excess out.

Best change directions to: "add small amounts and continue to check to ensure you do not overfill."

Also the dip stick stinks due to the extreme flat angle you do not get a very accurate reading especially removing from the tight location.

Need a vertical dipstick if that means an autmotive tube type or not.

yeah I am geeky engineer.

The OneWash Residential Series Power Washer will have an oil capacity of 20 ounces (0.6 liters). The “H” on the dipstick is the high (full) mark. When adding oil, it should be added to the “H” marking. Please note that these units are tested at the factory, and there may be oil left in the crankcase. Always utilize the dipstick when adding oil to ensure that the unit is not overfilled.
During operation, when the oil level reaches the “L” mark, that means the oil level is low, and oil should be added. The oil capacity information, as well as other specifications for this unit, are located in the Product Specifications section of the owner’s manual.

Maximum supply hose length

The manual states that the maximum supply hose length is 50 feet. I understand that some homes do not have adequate supply pressure from the source which could cause the pump to starve for water.

answer 2
The factory set pressure for the Generac’s residential power washer, model number 6602, is 3100 PSI. Due to the variation in engine speed, which is customer controlled with the throttle control, the PSI range, and pressure stream range, can vary. The unit will also come with 3 different nozzles, a 0°, 25°, and a soap applicator nozzle, each designed to tailor the stream of water to the job. Generac’s 3100 psi Power Washer is applicable to use on vinyl siding, so long as the appropriate nozzle is utilized. When utilized for cleaning siding, the unit is designed to be used with the black soap nozzle and the green 25° “wash” nozzle. The 25° “wash” nozzle has a rated pressure of 2600 psi. This pressure will be suitable for cleaning the siding on one or two story heights, but as the distance between the nozzle and the cleaning surface increases, the cleaning power decreases. The 0° red nozzle is the high pressure nozzle, and 25° green nozzle is a medium pressure nozzle. Always ensure you are aiming the wand in a safe direction, as the high pressure stream of water this equipment produces can cut through skin and its underlying tissues, which could lead to serious injury. Utilizing the proper pressure nozzle will ensure that the unit is effectively utilized on surfaces higher than ground level. Further information on the nozzles included and their suggested uses can be found in your owner’s manual. If you have any other product-related inquiries, please contact us directly at 888-GENERAC (436-3722).

The water supply must be adequate to handle greater than 3.8 gallons per minute and no less than 30 psi. We do not recommend siphoning standing water for the water supply, and ensure that you use only cold water (less than 100°F). Moreover, if you plan on attempting to utilize a water tank, the garden hose that connects from the water source to the generator would need to be attached appropriately, so as to provide the necessary water flow to your residential power washer.
