Dishwasher just over a year old. Very slow to discharge water. Line from washer to dispsoal clear. Have had inside of unit apart and see no obstruction of any type. Took water dispenser off, plaster shroud with 8 screws, impeler with center bolt attaching to shaft, and plastic part with 4 screws off. There are two white balls, marble sized lying in bottom of washer. left them there. Not sure what purpose they serve. Reassembled and it takes 3 rinse cycle to exhaust all the water. Any suggestions?

    I did check valve and appeared clear. Do the balls just lay in the bottom center of the dishwasher?

The little white balls are check valves - you need them.

Have you checked the discharge check valve under the dishwasher where the discharge line connects to the sink? It is under the unit and can be unscrewed (carefully). The valve can be disassembled with a couple of pronged keepers. This check valve can become obstructed and cause the problem you decscribe.

    Yes, they (the check balls) just lay there and prevent back flow from the sink.

    If the strainer under the lower rack/pump intake is also clear, you may have a bad drain slinger (sites under the main pump impeller), although after only a year that would be a little unusual.

    Have you checked the drain spur on the sink where the dishwasher drain hose is attached? Is the hose itself ok and not kinked anywhere? You can also check to be sure the hose isn't collapsed internally (you'll have to remove it). Also, does the sink drain ok?

    If you have a disposal and the spur is connected to this section. make sure the disposal is clear when the dishwasher runs.

Bosch SL1501B dishwasher doesn't drain water after the washing cycle. Also with new drain pump. What else could it be?

Check the following.
1. The drain hose has to be discharging at a high enough point to prevent water flowing back into the machine.
2. Make sure your drain hose is not twisted or kinked.
3 . Make sure your drain line is not blocked push a flexible hose down it to dislodge any fat/debris
4.If your drain line discharges into a shared drain with another appliance i.e. garbage disposal make sure it is not blocked.
5. You may have a blockage at the inlet to the pump which would slow down the pumping rate,
Since you mentioned the mushroom shaped float allowing the washer to empty this may be defective.
See the link attached.
Hope this helps.

The wall box outlet probably is about 1-1/2 in. in diameter. If it was snaked clear then there may be blockage in the main sewer line. In my case, there is a 90 degree bend that gets blocked periodically and causes the washing machine discharge to back up

Bosch front load washer...WFMC3200UC...6+ years old...light to medium problems UNTIL we now have an apparent slow leak into the drum when the washer is completely "at rest". I assume...

I would take the water pump ad trip it to clear the rotating shaft of possible cotton threds or other debris stuck in-between the rubber water seals as this can cause a slow dripping of the water as it creeps between the still shaft of the water pump eric

The water does not circulate throughout the washer. Is the pump bad? The full cycle will run without cleaning.

Before we jump to conclusions, you can try to clear element that discharges the water. The wholes in these units can become clog do to the detergent as well as food. Most Bosch units allow you to unscrew these pretty easily. Blow through them, or use a plastic tooth pick to clear any obstructions or both. Before you reattach, turn on dishwasher and listen to hear how much water is shooting out at the discharge points. Most Bosch have two discharge points one for the top and of course one for the bottom. Reattach units and Run dishwasher.

Should this fail it could very well be the circulating pump.

Dishwasher not emptying

either the pump is not working or the discharge hose is clogged, if you have an air gap on the sink take the hose off and hold it down see if the water comes out by tself if so the pump is bad if not the drain is colgged take out the bottom tray you will need a 1/4 inch nut driver take the plastic screen cover plate off clear it of debris, there is a sharp metal blade in there so be careful, after cleaning it out turn on to rinse and see if it drains if not you will need to either replace the dishwasher or the pump, dollar for dollar new dishwasher time

Water overflows from dishwasher during wash cycle

Food or debris could be blocking the drain line before the water pump or after. So unplug the unit or cut the power to it then begin working on the washer. You will need a pliers or medium size channel locks to take the hose clamps off. Make sure the line is clear from the unit to the water pump. Then check the pump over carefully. Then the line from to the discharge area. This should solve the problem.

Water Will not Drain

It could be cause the water level switch. The level switch is usually a diaphragm device with a small clear tube attached between the switch and the bottom of the washer's outer tub. I am not familiar with your machine,but if you will open the rear panel you will find it easily. Clear tube from any obstruction. Good luck !
