Do you meen filter? its in the bottom of the dishwasher under the bottom propeller. turn the plastic collar under the bottom propeller anticlockwise then lift it up and out then you can lift out the mesh filter. the other type has a winged collar that you turn then lift up then there is two filters in that to clean.

From the manual I found online here.
CLEANING AND MAINTENANCE COMPLETELY CLEAN AND DRY ALL PARTS AFTER EVERY USE. Always turn coffeemaker OFF and remove the plug from the electrical outlet before cleaning. Open the reservoir lid*. Remove the grinder basket lid by using the recessed area on each side of the lid. Then remove Grinder Basket. Open Filter Basket Door. Remove Filter Basket Cover, Filter Basket and Filter Basket holder. The grinder basket, grinder basket lid, filter basket and filter basket cover can be washed in warm soapy water and rinsed thoroughly, or cleaned in the upper rack of the dishwasher. Dry all parts after every use. Do not put any water in the unit once the grinder basket has been removed. Wipe the area under the grinder basket with a damp cloth. If water gets into the grinder motor, the motor may become damaged and may malfunction.
DECALCIFICATION Decalcification refers to removing the calcium deposits which form over time on the metal parts of the coffeemaker. For best performance from your coffeemaker, decalcify the base unit from time to time. The frequency depends upon the hardness of your tap water and how often you use the coffeemaker. To clean, fill the water reservoir to capacity with a mixture of 1/3 white vinegar and 2/3 water. Turn the coffeemaker on by pressing the ON button. One cycle should be sufficient to adequately clean the coffeemaker. When the cycle is completed and the five beeps sound, turn coffeemaker off. Repeat operation, this time using fresh cold water.

clean, clean, clean. check drain. bet the sink is slow.

There is a filter at the bottom of the tub that has to be cleaned out once in a while. Then it will drain. This should help. It is a plastic looking mesh filter most can be removed and hand washed. Hope this helps.

at the bottom left corner their is a manual draining system maybe you need to use that with a bucket.
thats all i can think of unless it still has warranty just trade it in.

I useto have same problem. For some reason there was water under machine, then i tilted machine, clean water and problem solved. This is built-in dishwasher that is why water acumulates under machine and "leak cut off switch" turn off machine. You can't reset machine while you have water under, machine telling you there is a problem, but Haier wan't put solution on their site - Haier suport is very bad. Sorry for English and hope this help.

I cleaned out the drain pump and non-return valve on my Miele G658/858 and that fixed the problem. The G841 may have similar parts. It's easy to do. In order: 1. Turn off washer. 2. Remove the triple filter (the basket on the bottom of washer with the little handle. Turn the handle and remove) rinse out and set-aside. 3. Remove the standing water. I used a wet vac to remove the standing water from the bottom of the machine, but you can scoop it out also. 4. Tilt the locking clamp (tilt left) to the side. (this is a metal wire covering the white plastic valve. This valve is to the right of the triple filter basket.) 5. Pull out the non-return valve and rise will under running water. You may have to wiggle the valve a little. Pull straight up and out. 6. The drain pump is beneath the non-return valve. (it has a little plastic propeller, like a paddle wheel, inside) 7. Spin the propeller several times in both directions to make sure it's clear. ( I used the shop vac with a small hose attachment to clear the drain above the propeller compartment) 8. Carefully refit the non-return valve and secure it with the locking clamp. 9. Refit and lock the filter in place.
I haven't had a problem since and my dished are much cleaner- The problem must have been coming on for a long time.
Hope this helps,
Susan

Most dishwashers have a little filter basket in the bottom. Depending on the brand, you can slide out the bottom rack, and in the bottom underneath the sprayer (the propeller thing) there should be some sort of basket that can be removed and cleaned. You also may have some water quality issues, or some detergents will leave residue. Also, make sure most of the large food is removed before loading.
