Where does the hose on right side halfway up hook to

mine has a clear push on hose in the back right side as you are looking at front

If you will open the door on the front of the dishwasher, you should see two small screws going through tabs holding the dishwasher to the countertop. They are in the front, and above the door.
If you will remove those screws, you should be able to pull the dishwasher out about halfway into the room.
Do not pull it farther, because there are 3 important components you want to leave hooked up. The electric wires, the drain hose, and the fill hose.
Remove the front lower panel that hides the bottom of the dishwasher, and you should see a water pump made of plastic maybe the size of your fist, maybe on the right side.
The drain hose should be attached to that pump, as should electric wires. The drain hose goes to the sink drain in most cases
Find a way to catch the water and or sludge that may come out of that hose, and remove the hose from the pump that goes to the sink drain. You may need a pan that holds a quart or more liquid.
See if that hose is clear of being plugged up.
Sometimes too much food left on the dishes can plug up the pump or the hose. Examine the pump to see if it is plugged.
If the hose goes to the garbage disposal, perhaps that is where the plug-up is.

This sounds like the hose from the tank breather, the hose goes from the tank on the l/h side to the cylindrical vent, then from the other side of the vent the hose goes around the back of the carb and out through the side of the crankcase with a sintered plug in the edn, there is also a hose from the cylinder base, this is the impulse tube and fits to the top of the pump cover of the carb,

I used to have 2 laundromats full of this model. I think you may be looking at the fill hoses...they are on the rear with hose bib threads... the drain hose is about 1" diameter hose coming out low on the back side. The drain hose goes inside the machine and attaches directly to the pump... If the 2 pipes close together are connected directly on the rear panel of the machine, those are the fill hoses and should be labeled with a C and H ...

There is a skimmer in the side of your tub( the part that skimms water off the top ) and what is called a main drain or a better tearm is deep suction that pulls water from the bottom of the tub and helps collect heavy dirt from in the tub these two lines ( three if there is more than one main drain) These will all come together and then hook to the front of the pump. If your filter is under the skimmer basket the top of the pump will go to the heater and then back to the spa. If your filter in not under the skimmre basket then it will come after the pump then on to the heater. So in answer to your second question, the front of the pump draws the water in and the top pushes the water out. But make sure that your heater is last in line so it only deals with clean water and it will not run on the suction side of the pump as it need water pressure in it to start and contious flow to keep it from over heating. Hope this helps.

Clogged AC drain hose.

You can see it by opening the hood and looking towards the back firewall.
Its a short black drain hose and will have a good rust spot under it.
To see it in the car you need to remove you dash. Lower your dash. Remove the screw on the right side and you can pull your dash out. The drain hose is located in the upper left side near the center hub and right near the engine firewall. Its a 6 inch black hose with a few bends and stubs out through a hole into the engine compartment. You can easily pull it out. and stick a short screwdriver up into the drain pan to clean it out.

That cap theory does not sound right...check for a heater control valve in-line on the heater hose and make sure than is opening and closing. I'd also disconnect both heater hoses, hook up a harden hose to one of them on the heater side and flush out the core.

the bigger hose is the drain hose smaller one is the fill hose you can also look the model no. up on line like sears.com and order the hose assembly that has both hoses and the end hooks to the faucet

Hello, I have just installed a similar model, and took the side panel off to see how it was put together ;)

The drain hose goes in the back of the dishwasher, then loops up the right side (as you are looking at the front)(this is to act as a "trap" to keep sewer gases from coming back into your washer, I assume), and then connects to the drain pump under the washer.

In order the change the hose, you will need to remove the left side panel, and the bottom panel, and this will give you access to the entire hose....

Hope this helps!
