To clean can I 1) hose it down with a dishwasher

First check this. Clean the water inlet filter at the tap outlet regularly. - Turn off the water tap. - Unscrew the end of the water inlet hose, remove the filter and clean it carefully under running water. - Replace the filter and screw the water hose back into position.
Then, if needed check this. Cleaning the filters
The filter assembly consists of three filters which remove food residues from the washing water and then recirculate the water. They should be cleaned if you wish to achieve the best results in every wash. Clean the filters regularly. The dishwasher should not be used without filters, or if the filter is loose. After several washes, check the filter assembly and if necessary clean it thoroughly under running water, using a non-metallic brush and following the instructions below: 1. Turn the cylindrical filter C in an anti-clockwise direction and pull it out (fig. 1). 2. Remove the cup filter B by exerting a slight pressure on the side flaps (fig. 2). 3. Slide out the stainless steel plate filter A (fig. 3). 4. Inspect the trap and remove any food residue. NEVER REMOVE the wash cycle pump (black detail) (fig. 4).
Always keep the door of the appliance ajar in order to avoid moisture from forming and being trapped inside the machine. Clean the seals around the door and detergent dispensers regularly using a damp sponge. This will avoid food becoming trapped in the seals, which is the main cause behind the formation of unpleasant odours.
Preventing unpleasant odours
Food residue may become encrusted onto the sprayer arms and block the holes used to spray the water. It is therefore recommended that the arms are checked from time to time and cleaned with a small non-metallic brush. The two sprayer arms may both be removed. To remove the upper sprayer arm, rotate the locking ring in an anti-clockwise direction. The upper sprayer arm should be replaced with the holes facing upwards. The lower sprayer arm can be removed by pressing on the side tabs and pulling it upwards.
Cleaning the sprayer arms
After cleaning the filters, replace the filter assembly and fix it in position correctly; this is essential for maintaining the efficient operation of the dishwasher.
Leaving the machine unused for extended periods
If the water hoses are new or have not been used for an extended period of time, let the water run to make sure it is clear and free of impurities before performing the necessary connections. If this precaution is not taken, the water inlet could become blocked and damage the dishwasher.
Cleaning the water inlet filter*
Disconnect the appliance from the electricity supply and shut off the water tap. Leave the door of the appliance ajar.
When you return, run a wash cycle when the dishwasher is empty.
That should cover all your bases

Make sure your water temperature is hot enough to dissolve the soap. Generally, the water temp. should be 140 degrees. Run some hot water at the tap before you turn on the dishwasher. This will assure that hot water is in the dishwasher as soon as you start it. Be certain that there aren't any large pieces in front of the dispenser tray. Sometimes casserole dishes, frying pans or baking pans can block the door and prevent it from opening.
Also, the sprayer arms might be clogged with bone fragments, peelings, bits of paper, etc. If this is the case, you'll need to remove the sprayer arm, flush and then check the jets. If you see "stuff" in the jets, they can be remove with tweezers.
Finally, make sure the upper sprayer arm hose is securely seated with the tube in the back of the dishwasher that carries the water up to the sprayer arm hose. If these two are not seated correctly, the water will not travel into the sprayer arm hose, the sprayer arm will not turn and your dishes will not get clean! I hope this helps. If it does, please come back to Fixya and rate my advice.

Your sprayer arms may be clogged. You can remove them by loosening the screws holding them in place. Flush them with the sprayer at your sink. If you can SEE residue (parts of paper labels, bone fragments, fruit peel pieces, etc) remove them with a tweezer.Reinstall the spray arms and see if that works.
Three more ideas:
(1) run a cycle without dishes OR detergent and use 1/4 cup of white vinegar instead. This will break down soil and "gunk" and help your dishwasher run more effectively.
(2) use an old toothbrush and clean the underside of the door INSIDE the dishwasher. The door will be open and you just brush the bottom of the open door on the INSIDE of the dishwasher. A lot of "crud" gathers there and can be redeposite on your dishes. We seldom think to check that area.
(3) the pipe that carries water to the upper sprayer arm MUST fit against the outlet in the back of the dishwasher. If it is dislodged or not seated properly, the water won't flow to the upper sprayer arm.
Hope one of these suggestions helps. If it does, please rate my suggestion. Thanks.

Hello Tx_smiths! We are terribly sorry to hear of your concern with your Whirlpool Dishwasher. Please respond back to this email address [email protected] with your name, reviewer name (Tx_smiths), phone number, street address, zip code, model & serial number, and date of purchase on the appliance. We would be happy to assist you. We look forward to your reply.

Hello
This is called the upper spray arm and there is a hole in the center of it that let's it slide on a shaft and then there is a cap that covers this shaft and helps hold it in place.
here is a web link that explains all of this and more ok so feel free to read all of it there is a lot of good information there

The sprayer arms seldom cause any trouble, but sometimes the spray holes in the arms become encrusted with detergent or minerals. When this happens, the holes must be cleaned out so that the arms will work efficiently. Remove the lower arm by twisting off the cap that holds it to the motor shaft. Wash it thoroughly with water and mild household detergent. Sharpen a lead pencil and break off the lead point. Use the tapered end of the pencil to **** out the holes. A wood manicure stick can also be used.


A clogged strainer can cause the dishwasher to flood or overfill. Clean the strainer regularly, or after each load of dishes is washed.Do not use toothpicks, matches, or metal objects for this job. Lightweight wooden sticks could break off in the ports, causing blockage; metal could scrape and enlarge the ports. After cleaning, place the sprayer arm back on the motor shaft and twist the cap back on to hold it in place. Follow the same procedure to clean the upper sprayer arm.
Removing and Cleaning the Strainer
The strainer is located directly under the lower sprayer arm. When the strainer becomes clogged with food and detergent debris, the dishwasher may flood or overfill. On some dishwashers, the strainer is a plastic or metal component consisting of two semicircular halves. To remove this type of strainer, pry it up. On other dishwashers, the strainer is a one-piece component. To remove this type, remove the cap that holds the sprayer arm on its shaft. Then remove the sprayer arm and the strainer.

Wash the strainer in the kitchen sink with water and a mild household detergent. Use a fairly stiff brush to get all the debris out of the holes and slots in the strainer. Rinse the strainer well and replace it. If part of the strainer lifts out for regular cleaning, check it and clean it -- if necessary -- after each load of dishes is washed.
Troubleshooting Leaks
If the dishwasher leaks, and you know the problem is not related to tub overfilling, the pump, or inlet valve problems, the plumbing connections may be faulty. Most dishwashers are connected to the water supply with metal pipe fittings, and the leak could be at these fittings. If the fittings are threaded, tighten them with an adjustable wrench. If this doesn't work, chances are the threads are stripped or the fitting is cracked or otherwise damaged. In this case, replace the fitting.
Most dishwashers discharge used water through a pipe or a hose connected to the drain or garbage disposer under the kitchen sink. If the drain line is made of flexible hosing, it may have cracked from prolonged exposure to hot water. Examine the hose; if it's damaged, replace it. If the hose is leaking at its connections with the disposer or dishwasher, tighten the fittings or clamps at the connections, or replace the clamps. Also check for water leaks around inlet valves, drain valves, and anywhere you see flexible hoses and hose connections. Leaks at clamps can be stopped by tightening or replacing the clamps. Leaks in hoses can be eliminated by replacing the hoses.

There are several possible causes.

First, make sure the machine is properly installed with the drain hose up in a loop or an air gap before going down to the drain. This is to ensure no dirty water or smells from the sour or garbage disposer backs up into the machine.

Sometimes nasty stuff gets trapped inside internal parts of the machine and inside the sprayer arms. It is normally easy to remove the sprayer arms for cleaning, on reasonably modern Bosch machines they can also be opened up for easy access.

There are also special dishwasher cleaning agents that you can use to perform periodic cleaning cycles. Some believe it is important to use rinse agents to minimize the problem, maybe it is worth trying if you don't use it.

If there is warranty left on the machine I would advise you to complain, there is a slight possibility there is something wrong in the machine for instance bad choice of insulation lining that have been known to emit foul smells.

Good luck with tracking down the cause of this!

It may also be a missing weight on the sprayer hose, or that the sprayer hose is obstructed. Open up the cabinet under the sink and look a half-loop of the sprayer hose that should be hanging down from the underside of the faucet. It must be able to descend without obstruction as you return the sprayer to the body of the faucet. If it is resting on a box of dishwashing soap or otherwise obstructed, then it doesn't have it's full weight to counterbalance the weight of the sprayer head. Capice? It needs the weight of the hose to 'weight it down'. Also, there should be a donut-shaped weight around the hose that should be able to freely slide to tha lowest position of the half-loop as the sprayer is extended and returned. Make sure that's working too.

The most likely is either a defective drain pump or a clogged drain hose.

if you dishwasher holds water that means the plumbing connections may be faulty. Most dishwashers are connected to the water supply with metal pipe fittings, and the leak could be at these fittings. If the fittings are threaded, tighten them with an adjustable wrench. If this doesn't work, chances are the threads are stripped or the fitting is cracked or otherwise damaged.

also it may be due to faulty pump
Servicing the Water Pump

In most dishwashers, the water pump is located under the lower sprayer arm. This component pumps the water through the dishwasher. The pump has two impellers, top and bottom. These, as well as other components, can become clogged with food or detergent. Here's how to disassemble the pump:

Step 1: Remove the cap that holds the sprayer arm on.

Step 2: Remove the sprayer arm, the screen, the pump housing, a bolt, the upper impeller, the food disposer blade, a spacer plate, the impeller hood, a flat plate, an O-ring, and the lower impeller. Lay the parts out in order as you disassemble them so that you'll be able to reassemble them properly.

Step 3: Clean the parts thoroughly with a mild detergent solution. If any parts are worn, replace them with new ones made for the dishwasher.

Step 4: Replace any seals, such as the O-ring or other washers, with new ones.

Step 5: Reassemble the pump, keeping the parts in order.

To reach the water pump, remove the sprayer arm and screen and then the pump housing. Remove the bolt, and the pump components can be disassembled.

On some dishwashers, the lower impeller serves as a drain pump. This type of system usually has a reversible motor; machines with nonreversible motors have drain valves, as detailed previously. If your machine possesses this impeller pump system, and the water will not drain from the dishwasher, clean the lower pump impeller. This may solve the problem. Otherwise, call a professional service person.
