Karcher p-washer shoots water out of chemical tube

[richez555]

I have a Karcher K 2400 HH pressure washer with a 5 HP Honda engine. Recently, water started shooting out of the chemical tube at full pressure. I need to keep the gun trigger engaged or it will blow the chemical tube right off the machine. I cleaned out the chemical tube opening, but water still shoots out. The chemical tube draws liquid if the soap attachment is on the gun. But with any high pressure fitting, water still shoots out. Any ideas?

The chemical tube is an injector that draws chemical. There's a check valve in it that has failed. If you don't use it, you can remove it, otherwise it needs to be repaired or replaced.

What do you mean by "remove it"? Thanks.

I don't use the chemical injection so removing it would be a great option. How is this done?

I don't know; can you upload a picture of it?

I looked at the parts blow-up, and the injector isn't a separate part, so it'll have to be fixed.
