Bosch Washing Machine Not Draining
The most common reasons your Bosch washer is not draining include: a clogged drain hose or drain pump filter, faulty door latch switch, clogged coin trap, or malfunctioned motor.
Don’t worry. I will explain how to fix these issues and get your Bosch washer back to work. However, before you proceed, here are some words of caution:
If your Bosch washer is under warranty, I recommend contacting Bosch support and asking for advice. Unfortunately, opening your Bosch washer will void its warranty in most cases, so leave it as a last option.
Inspect the Drain Hose
This is the first thing to check when your Bosch washer fails to drain the water. The drain hose is where the used water is pumped out of the washer.
If the drain hose is clogged, it won’t be able to pump the water out. Most of the time, people forget to take items out of their pockets before throwing clothes into the washer, blocking the drain hose.
To check the drain hose, first, disconnect your Bosch washer from the power source. Then, access the drain hose and check it for any clogs or obstructions. If there is any, remove it.
Clean the Drain Pump Filter
Almost all Bosch washers have a drain pump filter. However, over time, the filter gets clogged due to debris build-up and needs to be cleaned.
If you haven’t cleaned your Bosch washer drain pump filter for quite a long time, there is a high chance it’s clogged and is the leading cause of your washer not draining the water.
Check the Door Latch Switch
The door latch on the Bosch washing machine is designed to prevent the door from opening during the wash cycle.
The washer safety system will continue operating if the door is closed correctly. When the door is closed, a feedback switch sends a signal to the washer control board. If this switch is faulty, your Bosch washer won’t operate and drain the water, no matter if the door is closed.
The door latch switch is located beneath the control board on Bosch washing. So if your washer is under warranty, do not try to test it yourself, as it will void its warranty.
Even if your washer warranty period is over, I’d recommend seeking a professional help to test or replace the door latch switch on your Bosch washer.
Check the Coin Tap
This is one of the most overlooked parts of any washer. However, it may be the main culprit if your Bosch washer is quite old and you haven’t recently cleaned the coin tap.
The coin trap prevents foreign objects from getting into the drain. So, it needs to be regularly checked and cleaned; otherwise, it won’t let your washer drain the residual water.
Inspect the Drain Pump
If none of the above works, your washing machine drain pump may have malfunctioned. As its name suggests, the drain pump is the central part responsible for draining the water from the washer.
If your Bosch washing machine is under warranty, then you can get the drain pump replaced for free. However, if its warranty period is over, you will have to contact a repair technician to inspect and fix it for you.
When your Bosch washing machine is not draining, try the following solutions to fix it:
- Inspect and clean the drain hose
- Clean the drain pump filter
- Check the door latch switch
- Check and clean the coin trap
- Inspect the drain pump, and replace if faulty
