Bosch Dishwasher Not Draining
Bosch Dishwasher not draining is a common problem. The main reasons why it is not draining are because food debris has clogged in the filter, the water pump is damaged or the hose drain is clogged.
The filter plays a crucial part in your Bosch dishwasher’s trapping of food particles as well as preventing excess food and grease from being re-deposited in the dishwasher. If it is not regularly cleaned, it can become blocked by food residues thus preventing your dishwasher from draining properly.
If the filters are okay, then another likely culprit is a blocked drain hose. The drain hose is a crucial component of your Bosch dishwasher that carries dirty water away from the machine. Your drain hose will not drain water properly if it is filled up with food particles and grime. If the drain hose is in good shape, then the problem could be on the sink drain. The drain hose from the dishwasher is usually connected to the main sink drain and if it is blocked, then your dishwasher will not be able to drain water properly.
The final reason why your Bosch dishwasher is not draining is that the drain pump is damaged. Like the drain hose and filter, the drain pump can also be clogged by the buildup of grime and food leftovers thus damaging it. If you hear the drain pump producing weird sounds, then that is an indication that it is struggling because it is damaged.

Why is My Dishwasher Not Draining?
There are several reasons why your dishwasher is not draining. The first likely reason why it is not draining is that the filters have been blocked by food leftovers and grime. As mentioned earlier, a filter plays a crucial role in preventing small soggy bits of food from finding their way into the neatly cleaned dishes or clogging your drain.
Some filters are self-cleaning while others need to be cleaned manually. If your filter is not cleaned regularly as required by the manufacturer, then it will block, making it hard for your dishwasher to drain.
The motor also plays a key role in ensuring your dishwasher drains properly. If it is damaged, then that will seriously compromise the draining capability of your appliance.
Your dishwasher will also not drain if the drain hose that is connected to the sink drain is clogged. The drain hose is responsible for removing dirty water that has been used to clean your dishes to the main garbage disposal line. If it is filled up with food residues or grime, then it will not drain properly as it should.
Other possible reasons why your dishwasher is not draining property include a faulty timer, drain valve, or belt.

How to Drain a Dishwasher
You have probably experienced this at some point. You open your dishwasher ready to put your dirty dishes only to discover that a pool of grimy, soapy water is standing at the bottom of the dishwasher. If it is your first time seeing this, you may be confused about whether to hire an expert to drain the dishwasher or drain it on your own.
Draining a dishwasher is not as difficult as many people think. It is a simple process that will take you a few minutes to complete. In this section, we will give you a simple step-by-step process on how to drain a dishwasher.
Process of Draining A Dishwasher
Step 1: Prepare the Dishwasher
Prepare your dishwasher by removing all dishes that you had tossed inside. Also, switch off the dishwasher from the main socket to cut off the power supply. This will help ensure no damage to your utensils and enough space to work on the draining process.
Step 2: Use a Towel to Get Rid of Stagnant Water
Once you have removed all dishes from the machine, the next process is to drain the water sitting at the bottom of the machine. The best way to do this is by using a towel. This will help prevent any water leakage onto the floor.
Step 3: Check and Clean the Drain Hose
Once you have drained water from the appliance, the next crucial step is to inspect the drain hose. This will help you know why the machine is not draining. This crucial component is located behind the dishwasher or right under your main sink. Disconnect the drain hose then inspect it to see if it is in good shape. If it is blocked, use a small stick or wire to unblock it.
You may also use vinegar and baking powder at the bottom of the dishwasher and let it seat for about 15 minutes. Then run a rinse cycle at the highest heat setting.
Step 4: Check the Filter
If the drain hose is not blocked, check the filter. If it is dirty, remove it then clean it with hot soapy water before reinstalling it.
Step 5: Inspect Your Garbage Disposal
If you have a garbage disposal, you’ll need to inspect it and turn it on. This will help remove any backup of debris that could have been deposited in the drain line, allowing water to drain from the dishwasher. You’ll then need to run a rinse cycle and check if this solves the problem.
Step 6: Disconnect The Dishwasher From The Power Source
If the problem persists, unplug your dishwasher from the power source or try turning off the circuit breaker connected to the dishwasher to prevent electrocuting yourself.
Step 7: Check Your Sink’s Air Gap
You’ll need to check your sink air gap if you don’t have a garbage disposal. To check if this is the problem, you’ll need to remove it and then clean out any debris with a stiff brush. Once it’s all clean, return it back in place and try running your dishwasher one more time.
