Error E24 in a Bosch dishwasher: main error codes

Error E24 in a Bosch dishwasher often indicates clogging or breakdown of individual elements of the drain system. This could be a filter, circulation pump, hose or other parts. Sometimes the real cause is the control module, which may be affected by voltage surges. This article describes how to accurately diagnose a problem and how to carry out independent repairs.

Causes and self-remedies

Bosch dishwasher error codes appear at different times. In the case of E24, this can be either the beginning of the wash (after 2 minutes) or at the end of the cycle, when the unit must drain the waste water into the sewer. A message appears on the display and remains lit. Another sign is that the indicator with the faucet icon lights up. In this case, the device does not respond to requests and stops working.

If error E24 occurs in a Bosch dishwasher, most often this indicates a problem with the drainage system. For new models, this message lights up almost immediately after startup, since the unit tests all systems in advance. For older devices, it may appear only at the end of the cycle.

The main reasons that you can eliminate yourself are:

1. When a Bosch dishwasher showed error E24, this indicates a problem with the filters - they are clogged and can no longer drain water normally. Typically, filters should be cleaned after each cycle. If the corresponding code occurs, the device is disconnected from the network and the filter is checked, washed under running water.
2. Error E24 in a Bosch dishwasher may also indicate an electronics failure. Such cases are especially common after a sudden voltage drop in the network. Then it is recommended to remove the plug from the socket, wait 15 minutes, then plug it in again and check how the device will work.
3. Also, a similar code can appear for a very simple reason when the drain hose is twisted. It must be inspected along the entire length from the unit to the sewer. If necessary, straighten the hose to remove kinks. In extreme cases, it is better to replace it.

Other reasons

If all the described reasons do not apply, error E24 of the Bosch dishwasher indicates more serious damage. In the cases described below, it is recommended to contact a specialist.

Clogged drain system

If the filter is clean enough, but you cannot determine the location of the blockage, you need to disassemble and inspect each element:

• snail;
• pipe branch;
• drain pump;
• hose leading into the pipe;
• connection point to the sewerage system.

First, turn off the tap, move the unit away, remove the panel from behind and on top, and begin the repair. If any parts are badly worn, it is better to replace them.

Broken or clogged circulation pump

When a Bosch dishwasher shows error E24, this may also indicate wear on the circulation pump.It consists of a motor and an impeller, by the rotation of which the device determines whether there is water in the chamber. Over time, the bearings can wear out and begin to come into contact with the body of this pump, causing it to spin much less well. The part will need to be inspected and replaced.

But if the pump itself is fine, and error E 24 appears in the Bosch dishwasher, this may also indicate a clogged part. If the filters are not of good quality, food debris gets through them, which makes it difficult for the impeller to rotate. In such situations, it is enough to clean and rinse it, and then put the pump in place and test its operation.

Failure in the control module

The dishwasher also displays error E24 due to an electronic malfunction. On the board that is built into the device, the contacts may burn out or oxidize due to moisture ingress, as well as due to power surges. In this case, repairs come down to replacing individual contacts or installing a new module.

Thus, Bosch PMM error codes appear for various reasons. And even if the problem is related to the drainage system, it is often necessary to inspect several parts at once. It is possible to fix the breakdown yourself, but not in all cases.

For example, if it is connected to a circulation pump, you can open and close the chamber door while draining the waste liquid. Then the code disappears from the screen, and the model continues to work as before. However, it is worth remembering that this solution is temporary. Therefore, if the repair could not be carried out with your own hands, it is recommended to immediately contact a specialist.
