Karcher washer won't suck soap out of the bottle.

It's been a good washer for the 11-12 years that I've had it. Didn't use it for a couple months and this morning it would not suck soap out of the bottle like it always did before. Works good otherwise. The soap line is not plugged.

Anyone have an idea how to fix that?
 
My washer has different size nozzles. Are you using the correct size? If you pull the tube off can you feel any suction at the fitting while it operates? Is the tube collapsing?

Take an air hose and blow a little air through the suction line to clear it out. That works on my pressure washer.
 
Boss has one that has the same problem. I think they replaced the soap hose once because it had a tiny hole in it. Doesn't suck unless you keep the tank full of water either. Dealer supposedly fixed the problem but it still does it.
 
Mine will suck soap only when using the black tip. I have 4 tips, red,yellow,green and black. Black is used for putting soap, degrease before washing with washer.
 
The tube is open to the head on the pump. Must be something internal- either a blockage or a stuck valve?

It sprays good with the tip that I've always used before; just doesn't suck soap. I will use it this morning and then tear it apart and pull the head off the front of the pump and see if I can find the problem.
