Check that the suction tube orifice is not clogged.

If there is no detergent , then filter on detergent suction tube may be clogged.Remove filter, clean with fine needle and rinse with warm water.

I prefer to use a pump up garden sprayer for all chemicals/cleaners. Always check prior to using the dispenser/injector that the agent you use won't adversely affect the pump.
Thanks

What is causing water to leak out of the resovior when the power washer is running?


I am assuming you mean the chemical resovoir tank? If water is running out of it then water is coming back up your chemical injector. This usually means at some point the ball and spring in your injector got stuck...typically people take them apart at the nipple to ry and fix it. not realizing there is a small ball and spring in that nipple. This is actually a ball valve to prevent water from coming out of the chemical injector nipple. Replace the ball and spring if needed as well as the oring seat in the nipple. This will stop your tank from filling up. Good luck

How do I get chemicals to pull through my power washer?


this is a downstream injector which will only activate under low pressure normally a black nozzle with a large hole.A good way of testing is disconnect gun and wand assembly leaving the hose on the ground turn water on let it free flow no need to start engine.You should hear or feel suction out of hose barb if not try starting motor this time but this time you need to grab the hose so that it would not swing and hurt someone with engine running causing more flow should activate it.

Kranzle electric washer will not suck up soap


Hi, if it has a chemical injector on the machine then the pressure at the lance will have to be lowered for it to pull in soap. it works on a similar principle to how carburetors on cars pull in fuel, bernouli principle. high pressure at one side of an orifice going to low pressure at the other side which causes a negative pressure ( vacuum) which should pull in the soap. there should be a non return valve at the orifice (hole) which prevents the water back feeding into the soap container, it is quite common for this valve to get stuck, it is just a ball, spring and o ring , and the ball sticks to the o ring. if it is this system then take the soap pick up pipe off the injector and just push the ball off it's seat with a bit of wire.

If it is a high pressure soap system then that is different, but they usually work with an injector in my experience.

try taking the high pressure hose off the front off the machine and running it, if it has an injector on it it should pull in plenty off soap.

hope this helps ,
andy

I was able to use soap all last season, this year, i cannot get it to come thru, i know all about the low pressure deal, it seems to be clogged/ is there any way to specifically clean it where it enters...


Soap injectors are easily clogged or will not work because of design (air leaks will prevent chem from entering if chemical has to be drawn uphill) . They work with siphon action and will only work with very little pressure at the tip but good volume. If your siphon valve has the ball in place, however is missing the fine spring that holds the ball against seat (fine spring holds ball aginst intake fitting), the soap will not be sucked into stream. If ball and spring are in place, try elevating the soap container higher than the opening of the port (gravity feed may help to feed soap into system) . May be better to use an aftermarket downstream injector valve sold on ebay or many outlets. Cost about $20 but work better and are adjustable to save on soap. Search ebay for "Chemical Injector For Pressure Washers" or google "Pressure Washer Downstream Chemical Injectors" Various prices but lower price units work better than factory. Good luck

Craftsman Pressure Washer 580.752160 reagent/chemical not being dispensed when wand in low pressure position.


It is very common for the chemical injector valve on these to get gummed up from residual soap sitting in the valve. To clean it follow the chemical hose back to where it attaches to the pump. There will be a hex headed hose barb attached to it. Remove the barb from the pump. Underneath it you will find a spring and a ball bearing. Rinse the parts thoroughly and reassemble. You should also check the chemical strainer that goes into your chemical bucket. They can also become clogged and should periodically be cleaned.

Why want my pressure washer suction the solution while pressure washing the house?


The first problem might be that you are trying to use the wrong nozzle, see this link to read more about what nozzle to use for detergents

If you still have an issue the problem is going to be in the chemical valve on the pump, there are two different styles they have on this type of machine, look at the links below on directions on how to repair your chemical valve.

The injector might be worn out or have something inside of the valve causing it not to ****. If you are using a new high pressure hose or a longer hose this may also have an effect over the injector not working.

Genrac power washer chemical injector not working


How long is your high pressure hose and what diameter as it maybe to long and won,t **** chemical due to back pressure. To test this remove the high pressure hose and run the machine and check too see if any chemical is coming up the pipe. If it does then its a problem with your hose or the adjuster is not going to low enough pressure.

Chemical injection pump


There are three chemical injection pumps and using 2 different kinds of silicone tubings one is 45cc and the other 15cc you have to put back the original one in them and you can order them from their MFG service agency. Hope this can have you.
