How to fix:

Begin by shutting off the water supply followed by disconnecting the power. Next, inspect the water hose for any potential blockages or obstructions, initially examining for bends or cracks in the hose, and subsequently detaching it to verify it is not obstructed. If it is blocked, clear the obstruction and then reattach the hose. If the hose is clear, confirm the proper functionality of the water inlet valve. If it is not operating correctly, proceed to replace it.

Bosch dishwasher error code E1 or E2

What it means:

Begin by resetting your dishwasher by switching it off and then back on, waiting for five seconds before powering it up again.

Bosch dishwasher error code E4

What it means:

This error code indicates an issue with the water flow sensor within your Bosch dishwasher.

How to fix:

What it means:

This particular error code indicates a malfunction with the aqua sensor within your dishwasher.

How to fix:

Begin by resetting your dishwasher by powering it off, then turning it back on after a five-second interval. If the error code persists, find the aqua sensor and use a multimeter to check for continuity. If the sensor is faulty, it will require replacement.

Bosch dishwasher error code E5

What it means:

This particular error code indicates that your Bosch dishwasher is experiencing an overflow of water. This typically happens when the float switch within the dishwasher malfunctions.

How to fix:

Begin by resetting your dishwasher, first by switching it off, then back on after a five-second pause. If this doesn’t resolve the issue, proceed to test the continuity of the float switch. If it’s found to be defective, it will need to be replaced.

If your Bosch dishwasher is showing an E9 error code, it indicates an issue with the heating element. If the heating element is faulty, it may require replacement.

How to fix:

Begin by resetting your dishwasher: turn it off, wait five seconds, and then turn it back on. If this doesn’t resolve the issue, find the heating element and use a multimeter to check for continuity. If the heating element fails the continuity test, replace it. Additionally, if the heating element is cracked or otherwise damaged, it should also be replaced even if it passes the test.

Bosch dishwasher error code E15

What it means:

If your Bosch dishwasher shows the E15 error code, it indicates that the appliance is leaking water, triggering the flood sensor. To get your dishwasher back in working order, you need to address and repair the source of the leak.

How to fix:

If there is no visible water on your floor, the error code may be appearing erroneously. Try resetting your dishwasher by turning it off and then back on after five seconds.

Common causes of leaks include a faulty hose, or a cracked inlet valve or connection.

How to fix:

Begin by resetting your dishwasher: turn it off, wait five seconds, and then turn it back on.

After that, turn the dishwasher off and on again to see if the error code has cleared.

Bosch dishwasher error code E24 or E25

What it means:

Both of these error codes suggest an issue with your dishwasher’s drainage system.

How to fix:

Begin by resetting your dishwasher: switch it off, wait for five seconds, then switch it back on. If this step doesn’t resolve the issue, proceed by activating the drainage cycle and pay attention to the sounds it emits during the draining process. If you detect a humming noise, it suggests a malfunctioning drain pump impeller, which requires testing and replacement if found faulty. Conversely, if the dishwasher doesn’t attempt to drain at all, it indicates a complete failure of the drain pump, necessitating testing and replacement if deemed defective.

Bosch dishwasher error code H24

What it means:

This error code indicates a “24-hour delay.”

How to fix:

To initiate the reset process for your dishwasher, begin by powering it off and then on again, waiting for three minutes in between.
