1 Answer

I have a Bosch Classixx with what sounds the same problem.It would not drain properly and hummed even when the front door was opened.After a couple of days it ponged a bit.This is what I did.Sypnoned off yukky water with a short length of hose (fill pipe with water from tap don't **** on it!!).Cleaned filter under cutlery tray at bottom.Then put a TEASPOON of bleach if on main drainage or dishwasher cleaner if septic tank.Ran on a hot wash and see if it sorted problem-it didn't but did clean system.
Syphoned off again -take care.Isolated electric and water supply.-Should do that first perhaps Pulled out from under counter undid drain hose at sink end and water at machine end.I then put machine on side and undid bottom silver plate.Note position of polystyrene float switch cover.I then followed drain hose to drain pump and undid it by twisting it like a bayonet light bulb undoing clip levering with screwdriver (not for feint hearted as easy to break) -I then checked little impeller for foreign object-found none so pulled off pump housing by rubber hose to bigger pump thing next to it and found small bit of plastic put it back together and hey presto problem sorted-I was told it might take two hours for the expert to do it once on his workhop bench-it took me about 30 mins plus a bit of head scratching and a yank and push or two which could have been rather expensive -I was lucky!

Bosch Dishwasher stopped draining


If you hear the pump running, but little water drains, then check hose, and clean out debris trap at bottom of dishwasher. That gets plugged and needs occasional cleaning.

Water does not drain after washing the dishes. It just sits in the bottom of the dishwasher.


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. Also, check for any food pieces stuck near the pump impeller.
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.

My bosch dishwasher will not drain and makes a humming noise


Humming noise is an indication of your drain motor getting power but not spinning. Either your drain pump is defective and needs to be replaced, or something is stuck in the pump preventing it from draining out the water. Either way you will have to take the dishwasher out and get at the pump from the bottom of the machine.

Water in bottom of bosch dishwasher will not drain. How do I get this water to drain


Hi

Dishwasher not draining issue 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. To access the drain pump, please follow the procedure---
1. Drain pumps are mounted to sumps in the front of dishwashers --they're easily accessible from the front of dishwashers by removing toe kicks.
2. Tools needed: small flat blade screwdriver (for unlocking terminals).
3. Remove toe kick/base cover, pull up terminal cover and disconnect wires (using screwdriver to unlock locking terminals).
4. To remove pump, pull latch (on circular collar) & rotate pump clockwise (cw).
5. To install new pump, insert @ 2:00 position & rotate counterclockwise (ccw).
6. Clean water & debris from base, then check float operation.
7. Connect wires, then install base cover & toe kick.

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

Drainage problem


Regardless of the brand dishwasher, they all have the same fundamental plumbing. so.. you need to check a few basic things first..

1. Have you cleaned the drain filter or screen?
2. Is the drain hose kinked or restricting water flow?
3. Is your dishwasher pump blocked internally or the hose entering or exiting it ?
4. Is the house drain ( meaning : where that hose drains water into) restricting water flow? ( back pressure or clogged?

Any one of these conditions will manifest itself as an undrained dishwasher.. Hope this gives you some things to check and you get your problem resolved...
Good Luck

change your water pump or belt . Also make sure that no one just changed the garbage disposal and did not take the plug out of the disposal housing before installing the washer drain.
