How to get detergent to feed into Greenworks 1700 psi washer

The only way that it will feed detergent is by using the correct nozzle for the detergent. It's a lower pressure tip which allows the valve for the detergent to open. It's the black tip. It's either that or if it's an older one, there is a twisting wand that controls the pressure and spray pattern, which has to be twisted to the widest pattern with lowest pressure

WARNING: Do not allow PW to run "dry"

It is recommended that once pressure washer is in operation and water flow thru wand is there ,that you do not allow off period between burst of no more that 2 minutes or you highly risk damage to your pump,not engine, due to overheating. See if Dump valve is adjustable,cheaper models not adjustable. This valve senses pressure/heat build up in pump when trigger is released, and is a secondery backup to release such heat/pressure to avoid pump failure. If you have repeatly left trigger off for more than 2 minutes in for prolonged periods of time,this is not good.

Install high pressure hose. Cannot get shaft of hose fitting to go deep enough into fitting so retaining clip will engage

There are several different configurations for these fittings. If you bought a generic replacement hose, it may have a different fitting than what is on the machine. May have to replace the fitting on the machine, or buy a hose specific to your pressure washer.

My diesel burner on my pressure washer smokes real bad. Could I have a leak, if so where would that leak be? It is a alkota

HI, here is a few pointers that may help you ,
  1. if the smoke is white , that usually indicates water in the diesel, empty fuel tank and replace/clean the fuel filter
  2. if the smoke is black that indicates excess diesel or unburnt fuel , normal fuel pump pressure is around 8 to 9 bar (you will need a gauge to check this ), another cause is often failure of the fuel nozzle to correctly atomise the fuel (remove nozzle and clean (a small sintered fuel filter inside this )
  3. the burner electrodes should have a blue angry looking spark across them ,when checked (BE VERY CAREFULL WHILST DOING THIS as in effect you have a flame thrower ), usual gapping distances are around 6 mm
  4. the electrodes should be sharp pointed and not rounded or pitted
  5. a final cause is commonly a leaking fuel solenoid which can cause fuel to drip into the burner/heating coil assembly ( replace the solenoid
as you can see this can often be a complex and dirty job to repair and it might be better to contact a local service agent in your area .
Hope this helps

Losing pressure somewhere

Hi, I work in the italian factory of Karcher. In my opinion the problem is caused by the breaking of the collector. This is a black component of plastic where is inserted the detergent suction valve and the safety valve. To replace this component you have to go in a repair center Karcher.

Karcher HD 655 S Does not come up to full pressure

yes...check the check valve. A one-way directional valve, this part is also known as a DUMP valve. It opens when too much pressure builds in the hand wand (when not spraying water) in order to protect the pump, by returning the high pressure to its source reservoir. I suspect the DUMP valve is stuck in open condition (or nearly open).
