Water is not draining from Bosch Dishwasher 10 yrs old

The cirlce washes but the water does not drain away form the bottom. We cleaned filter but there is no obvious blockage or being able to unscrew further down to sump to see if there is lower blockage. Our machine is between 5-10yrs old. Do not if this is easily fixed or should we be looking to buy another? Please advise

1. Check for a clog in the air gap:
That's the silver dome on the back of the sink. Not all homes have an air gap for the dishwasher. (Though it is highly recommended!) Lift off the silver cover. Unscrew or unclip the plastic cap on the top. Look inside. Toothpicks are often found there.

2. Check for debris in the sump by:
Remove the lower rack, the lower spray arm, and screens. Use a #15 Torx bit to remove the cover over the drain pump suction. The hole leading to the drain pump is on the left at the bottom. Remove any debris you find.

3. If you find no debris, you almost certainly need a drain pump. After clearing any clogs, if you hear the drain pump humming, but it doesn't turn, replace the pump.
Comment back if you directions for this.

Good luck!

SOURCE: Bosch dishwasher has water in bottom after cycle is complete

Hi

Kindly check for the following :

Check for hose kinks or food plugging drain hose. Start at the drain port exit.
Check the check valve and drain hose for debris.
Check pump motor for reversing during the pump out make sure the dishwasher is pausing between the wash and drain cycles letting the pump/motor reverse for the drain cycle.
Check pump motor assembly for a drain solenoid, during the pump out make sure the solenoid makes that distinctive "clunk" noise
If you have recently installed a new garbage disposal, check knock-out plug at connection.

Check pump impeller for damage.
Check that the water inlet valve isn't seeping fresh water into the dishwasher when off.

Please contact for any further clarifications.

A Fixya Rating would be appreciated if.

Thanks

You can check the drain or the filter. You will have to pull it out of the space it is now to access it. Items will get stuck in the drain clogging it.

SOURCE: My Bosch shx46A05UC no longer will drain.....it

I ran into the SAME problem with my Bosch SHX46A06UC /21. The problem ultimately ended up being a clog in the air gap vent, (meaning, SOMEBODY ran the dishwasher without the bottom filter being in place or not in place properly). Remove the air gap cover and upper surface nut to drop the air gap vent into the area under the sink. Disconnect the hoses from the air gap vent filter (placing a bucket under the hose from the dishwasher). Run the drain cycle on the dishwasher. The washer should drain into the bucket and let you know that your pump works and that there are no clogs or kinks in the drain hose. (This will also remove the clog if so). The air gap vent's smaller hose connection is MOST LIKELY where your clog is. Look at the upper end of the air gap vent. You'll see a couple of clips on opposite sides of each other, that hold the air vent cap in place. Using a small screwdriver, (or your hands if you can), depress the clips (or one at a time) to get to the point where you can pull the vent cap off the filter. Either use water or a thin, long blade screwdriver to force any objects out of the filter. You should now have full flow through both branches of the filter. Using water and a rag, clean the vent cap and filter. Mount the air gap vent filter back onto the sink. Reconnect the hoses and remove the dishwasher's internal filter(s) and clean them as well while you're at it, making sure to remove any debris that might remain underneath the filter and has the chance of clogging the unit again.

Run the washer again to test. You should be good!

Cheers!

My bosch dishwasher does not drain the water away, left sitiing in bottom


Hi,

It could either be the filter (most likely), the drain pump (likely) or the drain hose/tube (least likely).

Normally, there would a filter somewhere at the bottom of your washing machine with the primary function of keeping loose clothing, torn fabric, lint, fluff and foreign objects away from the impeller/pump. Most current washing machine have self-cleaning filters and therefore regular cleaning is no longer a concern. However, some other washing machine need to have the filter manually removed and cleaned regularly or as even in your case. If the filter or grate is clogged or blocked with debris, it may interfere with the normal functioning of your washing machine and may cause the problem as you have described; water doesn't leave the tub.

To check the filter and/or the drain pump, the bottom has to be exposed, the filter/pump located and cleaned. In some instances, the drain could be a valve operated by a solenoid.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Hi

Dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. Check the drain hose for any visible clogging, remove if present. If no visible lint is present then remove then turn off the dishwasher and remove the drain hose and check for any visible clogging. If still not visible then the drain filter or drain pump is clogged and you'll need to clean the drain filter and drain pump.
Please note that dishwashers don't drain out the complete water such that heating element doesn't overheat. Hope this helps... Please post back for any further assistance.

Bosch shv56c03uc/114 Water is not draining


Check drain hose first.

If you do not find any blockage, then you will need to access the pump, remove pump hose and look for blockage in there.

If there is no blockage at all, then either the water level switch, a faulty pump, a wiring problem, or a faulty timer board can be cause the machine not draining.
