My Blomberg dishwasher will not stop draining once all the water is out. It is at the beginning of the cycle and it's like its stuck and won't move on to the next part of the cycle to bring water in.

I had a wine glass break in the washer, and a small shard of glass got stuck in the drain pump. Pulled the unit out, put it on its side and took the drain pump assembly apart. Removed the glass shard and its working well again.

Google on your particular dishwasher for help.

As soon as the waser begins the wash cycle pause, open door record water level in sump.

Close door and continue cycle until machine faults and stops.

Open door, record water level in sump.

Compare before and after. If level is low that the flapper valve that allows the water to drain is stuck open and the water is draining into the sink as the unit is washing.

To confirm, if the washer drain hose is connect to the neck of the disposal or sink drain, observe the drain after restarting the wash cycle from the beginning. If water is trickling out from the dishwasher while it is washing then it is confirmed the drain door is not closed if equipped with that configuration.

All washers have a process and hardware to drain. Some have a sepperate drain pump

Hope thisd helpd?

Hey friend, thank you for the post!
From my understanding you are trying to interrupt your dishwasher cycle without causing it to drain all the water out and then have to start it from the beginning. Once the door has been opened the wash cycle will stop and once it has been closed again your appliance would start up where the cycle left off. Hope this is helpful - Matt

Remove lower dish basket and inspect where water drains looking for clogged inlet

A common cause of this condition results from water in the base pan. This may result from a leak in the dishwasher or the drain hose (to the sink drain) backing up. First check the base pan (the very bottom assembly that all other components are mounted within) for any moisture - this can be difficult as there are only narrow openings between the tank and the base pan; a mirror can help or you might have to pull the unit out from the cabinet to access the sides. If there is moisture in the pan this problem must be corrected as the unit is just trying to protect against water damage from a leak. If the base pan assembly is dry, look at the float assembly (behind the water fill valve) as insects or rodents can sometimes interfere with the proper operation of this sensor. That causes the control to think there is a water leak. When this fault occurs everything is turned off and the drain pump runs continuously to eliminate any water from inside the dishwasher.

see this causes and fix it. God bless you
Belt, Water Pump Although few dishwashers have a water pump belt, if the dishwasher won't drain there might be a worn or broken water pump belt. After removing the lower kick panel the motor can be seen in the front, the water pump belt is on the bottom of the motor.

Drain Pump If the dishwasher won't drain, the drain pump might be defective. Test the pump motor with an Ohm meter. Drain pumps are not repairable, if it's defective it will need to be replaced.

Drain Impeller The drain impeller is attached to the pump and pushes the water out of the dishwasher, through the drain tube and into the garbage disposer or drain line. If the dishwasher won't drain, the drain impeller might be broken or worn out. Replace both the impeller and seal at the same time.

Drain Solenoid Kit If the dishwasher won't drain, the drain solenoid kit might need to be replaced. The drain solenoid is an actuator that opens a flap to allow the water to drain.
Drain Valve The drain valve can get clogged with debris and should be cleaned out if the dishwasher won't drain. If it seems clear of debris but won't actuate, it will need to be replaced. The drain valve is not repairable.
Pump and Motor Assembly If the dishwasher won't drain, the pump and motor assembly might be defective. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won't run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might need to be replaced.

Clogged or Improperly Installed Garbage Disposer If the dishwasher won't drain and the garbage disposer was installed recently, the installer might have forgotten to knock out the drain plug from this disposer. All garbage disposers are sold with a solid plug in the drain tube for situations where a dishwasher isn't connected. However, if the dishwasher is connected, the plug will need to be removed. If the disposer wasn't replaced recently, remove the dishwasher drain hose from the disposer and clean out both the fitting on the disposer and the end of the drain hose. These are the most common places to find an obstruction if the dishwasher won't drain.

Drain Hose If the dishwasher won't drain the drain hose might be clogged. Remove the drain hose from both the dishwasher and the sink drain to clean it out. The most common place for an obstruction is at the garbage disposer.

Check Valve If the dishwasher won't drain the check valve might be stuck closed. The check valve is a small plastic device which prevents water from returning to the dishwasher after it has drained. If the valve gets stuck closed, it will prevent the water from draining. The check valve is the device that the drain hose is attached to on the dishwasher
Check Ball If the dishwasher won't drain the check ball might be stuck. The check ball is a small plastic ball in the check valve which prevents water from returning to the dishwasher after it has drained. If the ball gets stuck, it will prevent the water from draining also. The check valve is the device that the drain hose is attached to on the dishwasher.

Hello

your Whirlpool dishwasher stopped draining mid-cycle, check your circuit breaker or fuses. The cycle won't complete if the power is interrupted. Reset the circuit breaker if tripped, or change out any blown fuses. Fully close the dishwasher door, and restart the cycle if you opened up the door. If you have not used the dishwasher in a while, the motor may be stuck. Open up the main housing, and rotate the motor until it turns freely. You must replace the motor if it's corroded or won't move since it's unlikely that you can fix it.

Pump

The pump is located underneath the lower rack and spray arm. This component is responsible for pumping water out of the dishwasher once the cycle is complete. If the pump isn't working, verify that it is not clogged with debris. Use a toothpick or plastic utensil to remove food particles from it. Check the pump impeller. If a section of it is broken, get a new pump since the impeller is difficult to fix.

Clogs

Clogs in the air gap or drainage hose prevent water from leaving the tub. Clean these components and the water inlet filters, if dirty. Examine the drainage hose, and straighten it if it's kinked. If the hose is badly crushed, you must replace it. Unscrew the drainage hose from the dishwasher to clean it, but reattach it before you restart the cycle. Run the food waste disposer if it's connected to your Whirlpool dishwasher. Remove the knockout plug from the disposer if you have just installed the disposer or dishwasher.

Drain Valve/High Drain Loop

Whirlpool dishwashers have drain valves with an internal solenoid. This valve opens and closes to drain water out of the tub. If the drain valve is stuck, lubricate the lever, and remove any debris clogging the valve. Remove any objects that are preventing the drain valve from freely opening and closing. If the valve is not working properly, you must replace it. Always install a high drain loop to prevent water from the sink entering your dishwasher. Create a loop of the drainage hose that is at least 18 inches high. Attach this hose beneath a section of cabinetry.

by the descrition you are giving you will need to replace the main control board.Part number 154568401.you may also need to check the float switch.The part will run about 110.00 dollars from a local parts store

All power and sounds should stop when any dishwasher door is opened.
Your door switch may be stuck causing it to continue.
The 90 second sound at the beginning of the cycle is the water pump extracting any residual water before taking on clean water for the wash cycle.
Any excessive noise from the drain pump could be debris in the pump. e.g. broken glass.
You can remove the pump and check it for blockage or any foreign object.
