Where do I connect the tubing from the soap dispenser to spray soap?

I own two pressure washers and one is a large and traditional design and soap enters the system through a thin flexible tube connected via a valve at the pump intake. When soap is required the tube is inserted into the soap container and the valve turned on or just half way on depending how much soap is needed.

The other is a modern compact and the soap dispenser is a one litre spraygun affair that clips over the end of the lance...

A tube has to be connected to the soap port tube on the pump to the dispenser.

Hello Eric, thank you for your post!

I understand that the dispenser on your Frigidaire dishwasher opens but the soap is not dispensing into your dishwasher. How old is your dishwasher soap? If it is around a year old you may need to discard it and use a new soap. Also check to make sure when you stack dishes that they are not obstructing the arms from reaching the dispenser. Make sure your spray arms are clear of any debris that could block the distribution of water inside of your dishwasher. You may need to connect with a professional technician for proper repairs if these steps do not correct your issues. I hope this information is helpful to you. -Matt

Make sure you're not loading the dishwasher with large items close to the soap dispenser. These can block the action of the dispenser door. Also, be sure the water temperature is 140 degrees for the best cleaning efficiency.
Another thing may be that your spray arm jets are clogged.
Depending on the model, the lower spray arm generally has a nut or thumb/butterfly screw (plastic) that you remove and then lift the spray arm off. I always soak mine in hot soapy water and then flush with hot water. If debris such as pieces of paper, bone, peelings are in there, you'll need to take a tweezer or toothpick to remove them from the jets. The upper spray arm usually has the same apparatus and you can follow the same procedure.
The upper spray arm receives water pressure from a tube that runs up the back of the machine on the inside. If the connection has been knocked out of line, the water can't flow through the tube to the spray arm. My kids used to knock ours loose when they loaded the lower shelf. Pull out the top shelf and see if the plastic connectors are in place. If not, snap them back on the shelf supports and this should align the tubes.
One more thing: the bottom of the door..on the INSIDE of the machine.It's amazing how much "gunk" settles and accumulates under there. I use an old toothbrush, moistened in soapy water to scrub the underside of the door. Then pour hot water on the area. Next run a regular cycle with NO items in washer and use 1/2 cup white vinegar...no detergent.
I hope these suggestions help your problem. If so please come back to Fixya and rate my advice!

Make sure the clear tube is inserted into the pump head properly.Make sure the tube is not kinked. try filling the bottle full of water and try pumping the water out first. Sometimes the dispenser gets an air lock and takes a bit of continuous pumping to get it to work

We had water pour out of the dispenser of our Kenmore HE2 washer. hot water helped us for one load then i realize that a trapped rag was the problem We were actually able to pull the face cloth out of the intake tube without taking everything apart!
opened the washer door and feel around inside the rubber seals to find where the intake tube connects to the drum (upper-left side). felt a small bit of cloth sticking out of the tube and were able to slowly work it out by pulling back and forth. and pulled it completely out thats all it was try this

Here is the fix

if the balls fell out you need a new head,sorry.

Growand:

There is a rubber tube which supplies water to the top spray arms. That is, If yours has top spray arms. This rubber tube has to make a connection when one slides the top rack back in. That tube will rot after a while, check it out.

If the soap is not being used up, reduce the amount of soap you are using and run the dishwasher empty with a pie plate sitting on the bottom rack with a cup of distilled (cheap) vinegar in it. Run it hot and long, recheck and redo if neccessary.

If you remove the top cover you will see the soap dispenser unit on the left. It has a large rubber hose connecting it to the drum. If you remove two screws at the front you can free the dispenser for maintenance. You can undo the clips on the various hoses and check that they are clean.

Some people report some dripping from the soap dispenser even when the hose is unblocked. This seems to be a design fault.
