01 - Bosch Washer/Dryer Combo Drain Pump
Sometimes, small objects or articles of clothing can get caught in the drain pump. To determine if anything is blocking the drain pump, remove the drain pump and check the pump for obstructions. If the drain pump is clear of obstructions, but is still noisy during the drain cycle, replace the drain pump.

02 - Bosch Washer/Dryer Combo Control Board
Since a washing machine control board provides voltage to nearly all of the washer's electrical components, a faulty board may not be sending power to the drain pump during the drain cycle. You can inspect the board for signs of burning or a shorted-out component. You can also use a multimeter to test for incoming power to the drain pump after reviewing the appliance's wiring diagram. If no voltage is present when the washer is in the drain cycle, it's likely the control board is defective and will need to be replaced.

03 - Drain hose is clogged or kinked
Check to see if the drain hose is kinked or crushed. If your washer "dances" during cycles, it may have moved and kinked the hose or the drain hose could be clogged with lint or hair. You can use a thin, long-handled brush to clean the hose.

04 - Clogged Pump or Hose
Foreign objects such as lint, coins, or safety pins may be clogging the pump or drain hose. Confirm the hose is free of debris and is not kinked. Most front-load washers have a removable drain trap behind a small door near the bottom of the washer to keep items from getting to the pump. Unplug the washer for safety, then inspect the drain trap and remove any items as needed.

05 - Bosch Washer/Dryer Combo Lid Switch Assembly
The lid switch assembly prevents the washer from spinning when the lid is open. If the lid switch assembly fails, the washer will not drain. To determine if the lid switch assembly is defective, use a multimeter to test each of the lid switches for continuity. If a lid switch does not have continuity, replace it.
Highly Likely
06 - Bosch Washer/Dryer Combo Water Pump Belt
Some older washing machines are equipped with a water pump belt. If the water pump belt is broken or worn out, the washer will not drain. Check the belt and replace it if it shows signs of excessive wear.
