Discovering that your kitchen is flooded or your dishes remain dirty is frustrating, but getting Bosch dishwasher E24 error code flashes on the display can feel even worse.
This specific error code is a common notification from Bosch appliances, usually indicating an issue with the drainage system.
The good news is that you do not always need to call an expensive technician immediately.
Many homeowners find that they can resolve this issue with a bit of patience and some basic household tools.
Understanding the E24 Error
Before you start taking your dishwasher apart, it is helpful to understand what the machine is trying to tell you.
The E24 error code essentially means that the dishwasher cannot drain water properly.
In most cases, the machine detects that the pump is not moving water out of the basin, or it senses an obstruction that prevents the drain cycle from completing.
This could be caused by a simple clogged filter, a kinked hose, or, in more severe cases, an obstruction within the drain pump impeller itself.
Immediate Troubleshooting Steps
When you see the error, do not panic.
Follow these systematic steps to diagnose and potentially fix the issue without professional assistance.
The Quick Reset
Sometimes, the E24 error is just a minor electronic glitch.
Before performing any manual labor, try to reset the dishwasher.
Turn the machine off, wait for about 30 seconds to one minute, and then turn it back on.
Run a short rinse cycle.
If the machine completes the cycle without the error reappearing, it might have been a temporary sensor hiccup.
However, if the error returns, you must move to the more physical inspection steps.
Cleaning the Filter and Sump
The most common cause of drainage errors is debris trapped in the filter.
Over time, food particles, grease, and even small pieces of broken glass can accumulate.
To fix this, locate the filter at the bottom of the dishwasher basin.
Twist it to unlock it and lift it out.
Rinse the filter thoroughly under hot running water, using a soft brush to remove any grime.
While the filter is out, inspect the sump area—the circular space where the filter sits—for any large objects or debris that might be blocking the water flow.
Inspecting the Drain Pump Impeller
If the filter is clean but you are still getting the E24 error, the issue may lie with the drain pump.
The pump has a small impeller that pushes water out; if this is blocked by a small object like a toothpick or a cherry pit, the pump cannot rotate.
Accessing this requires removing the pump cover.
Consult your dishwasher's manual to find the exact location of the pump cover.
Once removed, check the impeller—the small fan-like component—and gently spin it with your finger to ensure it moves freely.
Remove any obstructions found in this area.
Checking the External Drainage System
If the internal components are clear, the blockage might be further down the line.
Check the drain hose that connects your dishwasher to the sink’s waste pipe or the garbage disposal.
Ensure there are no kinks, bends, or pinches in the hose.
If you recently installed a new garbage disposal, ensure the knockout plug inside the disposal inlet has been removed.
If the hose is clear, check your sink's drain pipe, as a clog in your kitchen sink can also prevent the dishwasher from draining, leading to the E24 error.
When to Call a Professional
If you have cleaned the filter, checked the pump, and ensured that the drainage hoses are clear, but you are still getting the error code, the problem may be an electrical fault with the pump itself or the control board.
At this stage, it is advisable to contact a professional technician.
Attempting to repair electrical components or replacing the pump motor requires specific knowledge and tools.
Safety should always be your priority, so if you feel uncomfortable handling the internal electronics, do not hesitate to reach out to certified repair services.
