Removing filter/strainer to clean

If the arm spins easily by hand, but won't spin when operating, that points to poor water delivery...
1) check the strainer. Not just the holey one you can see, but there might well be a very fine mesh filter under it ~ if so, remove it to clean it (it can appear clean, but still be clogged with transparent cellulose fibres). Try running the machine empty without the strainer/filter fitted. You should hear a difference if the filter was causing the problem.
2) you might have a weak impeller. After a while the plastic impeller on some machines just wears away, leaving insufficient fins to move the water, this can be accelerated by e.g. broken glass stuck in the pump. Impellers can also slip on the motor shaft; the motor's spinning but the impeller doesn't. This means removing the machine, turning it over and removing the pump for inspection...

Run Lemi shine through it several times and then try to remove the filter.

Hello,

To clean the filter what ya do is
remove the lower rack
unscrew the center wash tower off of the lower wash arm
remove the screws from the pump cover (the almost frisbee shaped part with the stainer around the bottom of it)
lift off the pump cover...directly below the pump cover will be the filter it will pull off and can be cleaned in the sink.


this link is a drawing of the pump for your model http://c.searspartsdirect.com/lis_png/PLDM/M0112066-00006.png

the center wash tower is items# 1,27
the screws for the pump cover is item # 5
the pump cover is item # 4
the filter is item # 6

Incorrect level. Check level at operating temps and while the engine is running. By sump and stainer you meant that you removed the oil pan off the car and cleaned the pickup tube of the oil pump? I'd suggest hooking up an oil pressure gauge so you'll know which part of the engine is starving oil and setting the warning.

Hello- A clog in drain hose or debris in sump strainer is most likely cause. Strainer may be accessed by removing accumulator cover. Clean out debris and should drain fine. Let me know if this info helps- have more if needed. Thanks- Ed

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.

I have had the same problem and finally stumbled upon the answer today!

If you are looking inside your dishwasher, look mid way up the right side wall and there is a valve/hole...if that hole is covered up (e.g. cutting board, ect) it will cause water leakage.

Weird huh? But that recommendation is coming straight from the Bosch headquarters in Canada. I would not have believed it otherwise, but I have read this solution twice, and now myself, have not had a leak since I stopped placing things over that hole! My model is SHU3326UC.

Yes, you will need to purchase a set of torx style screw drivers at your local hardware store. Remove the upper and lower spray arms and clean the debris out of the spray holes. Remove the screws that hold the filter in place and remove the gunk out of the sump. In the future stop using gels or gelpacks, just use electrasol powder or cascade powder. The gels and gelpacks clog up dishwashers like you would not believe. Run some Lemi-shine through the machine on a monthly basis, Lemi-shine is available at most walmarts.

Disassembled solenoid, found plugged inline strainer (caused by water shut-down in building to replace recirc. pump) Pulled and flushed filter basket, problem solved. Solenoid must be removed to access filter which is in sol. body. I hope this can help anyone who does'nt have a tech manual or flow diagram.
