If if won't pump all water out, the d/w hose or sink drain is plugged.
if it is a braided hose, it just deteriorated due to age.
Yes. Your dishwasher discharge hose is probably hooked into the side of the disposal. Running your disposal will not hurt the dishwasher.
If it goes into a garbage disposal, the disposal needs cleaning. If it goes into a tube in the sink drain, check that for plugs. Is the drain hose open all the way, no kinks?
The sink drain is plugged,or you have the dishwasher hose hooked up in wrong place.
The hose is soft and mushy inside. Replace the hose. Possible clogged radiator. Replace the hose first. You also might have a clogged radiator core. Have a reputable radiator shop check and flush your cooling system.
It i on the air cleaner box--there is a long tube going from the intake to the air cleaner box and the mass airflow sensor sits right on the hose/plugs into the hose--you can't miss it
Probably the drain hose from the dishwasher isn't high enough to keep the water from running back . The hose should be above the level of the disposal at some point. Some states require an "air gap" which is a device that is placed in the drain line to prevent this. Some states require a simple high loop in the drain hose. Many dishwasher manufacturers are now installing backflow preventers in the dishwasher.
In the air intake hose leading to the throttle plate
This is usually the result of a clogged exhaust hose.
You would have to put a casing around it, find a different incoming water hose, and adapt the drain hose.
If the dishwasher is hooked into a garburetor, there is a plug in the garburetor where the hose drain attaches that needs to be knocked out. The drain hose might be plugged where it joins to the plumbing drainage. The other problem, plumbing-wise, is the drain hose has to be fed as high as it can go under the sink and back down into the drain.
There may be a filter screen in the end of the hose that is clogged. The supply line to the hose may be clogged. The filler valve that lets water in may be bad.
