Why is my GreenWorks Pressure washer soap not working? 5 Reasons with Easy Fixes

A GreenWorks pressure washer soap dispenser may fail to work for several reasons, and understanding these issues can help you troubleshoot and resolve the problem. Here are a few common reasons why your GreenWorks pressure washer soap not working properly

1.      Clogged or Incompatible Soap Nozzle

The nozzles used for soap applications differ from other nozzles in the pressure washer. A soap nozzle generally has a wider angle but a low-pressure setting. The main reason for having such a setting is that the detergent suds easily get clogged in other nozzles with narrow spray angle. High-pressure nozzles can also force the detergent back into the tank. Hence, it is very important that you only connect a nozzle specific for soap application. In case, you have lost the soap nozzle, use the next widest angled available nozzle.

Secondly, Soap or detergent residues might accumulate and block the siphon tube over time or the nozzle on the soap dispenser, which will hinder the appropriate flow of soap.

Solution: The nozzle and siphon tube should be cleaned and checked for obstructions before being removed. If clogs are found, use a tiny brush or a thin wire to remove them.

2.      Using the wrong detergent or soap

All pressure washers come with a user manual stating the most compatible pressure washer detergent meant for the model. GreenWorks pressure washers are also detergent-specific and can be highly non-performing with any other detergent. Using the incorrect soap or detergent might result in inappropriate soap flow or a lack of foam generation, as explained.

Solution: Ensure that the soap or detergent you’re using is made for pressure washers. For advice on which soap to use, consult the manufacturer.

3.      Improper soap-to-water ratio

The performance of the soap dispenser might be impacted by a soap-to-water ratio that is either too high or too low. Mostly, the detergent used for the soap tank is more viscous as compared to regular soap. It is always better to prepare the right soap-to-water ratio in a container and then transfer it to the detergent tank. If the right ratio is not achieved, the detergent might be stuck on the tank’s outlet, which will cause your pressure washer to not pull soap.

Solution: Examine the soap dispenser valve for flaws or damage. Replace the valve if necessary, or get a pro to fix it.

5.      Siphon tube or connection air leaks

The purpose of a siphon tube is to help the detergent travel to the end of the nozzle. It is quite possible that the pressure washer not siphoning detergent due to a blockage within the siphon tube. Also, Air leaks in the hose couplings, seals, or siphon tubes can interfere with the suction operation and prevent soap from being sucked in.

Solution: Check for leaks or loose fittings at all connections and seals. To ensure a proper seal, tighten or replace any broken pieces as necessary. Also, make sure that the siphon tube is free of all the blockages.

6.      Broken Soap injector

If you still find your GreenWorks pressure washer soap not working, then it is quite possible that you have a broken soap injection system. The purpose of the soap injector is to mix the detergent and inject it into the high-pressure water that is about to shoot out from the spray nozzle.

Solution: To replace a broken soap injector system, turn off the pressure washer, disconnect the tubing connecting the soap reservoir to the injector nozzle, remove the old injector system, install the new system securely, secure the tubing, test the pressure washer, and dispose of the old system according to local regulations. Follow the manufacturer’s instructions for each model and ensure proper soap dispensing. However, it is recommended that you get assistance from a professional to get it repaired.
