A Blomberg dishwasher that isn’t draining can be a frustrating issue, but don’t worry; it is possible to fix it on your own.
Dishwasher drainage problems are relatively common, and most of the time, the solution is simple and doesn’t require professional assistance.
In this article, we will provide you with the information you need to understand the potential causes and the steps to resolve the problem.
Before getting into the details, knowing how a dishwasher drains is important.
The dishwasher is connected to a drain hose that runs water into the pipes under or into your sink.
Sometimes, the plumbing connections in your sink can begin to deteriorate and need replacement, or excess debris may be clogging the bottom of your unit.
The dishwasher filter, drain pump, or drain hose might also have issues.
In the next sections, we will discuss various ways to troubleshoot your Blomberg dishwasher and address the drainage problem.
By following the recommendations, you can save time and money in getting your dishwasher back to running efficiently again.
Why is Your Blomberg Dishwasher Not Draining
There could be several reasons why your Blomberg dishwasher is not draining properly.
Here, we’ll discuss some of the potential causes to help you identify and resolve the issue.
1. Clogged Drain Hoses
One common reason for a dishwasher not draining is a clogged drain hose.
Over time, food particles and other debris can accumulate inside the hose, leading to a blockage.
To check for a clog, disconnect the drain hose from the sink or garbage disposal and inspect it for any obstructions.
If necessary, clean the hose and reattach it securely.
2. Faulty Drain Pump
A malfunctioning drain pump might also be responsible for your dishwasher’s drainage issues.
The drain pump is responsible for pushing the drain water out of the dishwasher during the drain cycle.
If the pump is damaged or faulty, it may need to be replaced.
For Blomberg dishwashers, AP6992857 Drain Pump or a compatible pump like Supco DW995 can be used as replacements.
3. Blocked Dishwasher Filter
A dirty or blocked dishwasher filter can prevent proper water drainage.
If you haven’t cleaned your dishwasher filter in a while, it may be time to give it a thorough cleaning.
To access the filter, remove the bottom rack and locate the filter assembly, which is usually at the bottom of the dishwasher.
Clean the filter thoroughly and reinstall it as needed.
4. Obstructed Drain Pipes
Sometimes, the problem is not within the dishwasher itself but in the drain pipes connected to it.
A clogged kitchen sink drain or other connected drain lines can cause the dishwasher to have difficulty draining.
Inspect the drain pipes and clear any blockages to ensure the smooth flow of water.
How to Fix a Blomberg Dishwasher Not Draining
If your Blomberg dishwasher is not draining, there are several possible causes.
Here are some steps you can take to troubleshoot and resolve the issue.
1. Check the Dishwasher Drain Pump
The drain pump is responsible for removing water from the dishwasher after the wash cycle.
Ensure that the drain pump is functioning properly and is free from any blockages, such as pieces of food.
If the drain pump is damaged or malfunctioning, you may need to contact customer service for a replacement.
2. Inspect the Dishwasher Filter
A clogged dishwasher filter can prevent the dishwasher from draining.
Remove the filter and inspect it for any debris, such as food particles or buildup from hard water deposits.
Clean the filter thoroughly and reinstall it according to your installation manual’s instructions.
3. Look for Blockages in the Drain Hose
A blocked drain hose can prevent water from exiting the dishwasher.
Disconnect the hose from the dishwasher and sink drain and inspect it for any clogs or kinks.
Use a wire hanger or a long brush to clear any blockages and ensure the hose is properly connected, with a hose clamp if necessary.
4. Verify the Water Inlet Valve
The water inlet valve controls the flow of water into the dishwasher.
If it becomes stuck open or malfunctioning, it can lead to drainage problems.
Check the water pressure and ensure the valve is functioning correctly for proper operation of the dishwasher.
5. Consider a Water Softener
Hard water deposits can build up in your dishwasher over time, affecting its performance.
Adding a water softener to your dishwasher can help improve water quality and prevent build-up that can interfere with the dishwasher’s ability to drain.
By following these steps, you should be able to identify and resolve the issue with your Blomberg dishwasher not draining.
Remember to refer to your installation manual for specific instructions on the proper maintenance of your dishwasher and consult customer service or a professional technician if necessary.
How to Prevent the Problem
To prevent your Blomberg dishwasher from not draining, follow these steps:
1. Clean the dishwasher filter regularly
Make sure to clean your dishwasher filter; built-up debris can restrict water flow and prevent your dishwasher from draining properly.
Check the manufacturer’s guidelines on how often to clean the filter to ensure optimal performance.
2. Inspect the dishwasher drain pump
Periodically, inspect your dishwasher drain pump for damage or foreign objects that can obstruct its function.
If it is faulty or clogged, make sure to remove any debris or replace the pump as necessary.
3. Install a high loop in the Crosley Dishwasher Drain Hose
When connecting the dishwasher drain hose to your sink or garbage disposal unit, make sure to create a high loop.
This will prevent backups from the sink and ensure proper draining.
Consult the dishwasher’s installation manual for guidance on proper positioning.
4. Run your dishwasher through a complete cycle
Running your dishwasher through a full cycle ensures that the pump and plumbing system function correctly.
If you catch any issues early on, you can address them before they become more significant.
5. Check your garbage disposal unit
If the dishwasher and garbage disposal unit are connected, make sure to run your garbage disposal before starting the dishwasher.
This will clear any food debris that might clog the drain.
