Error E24 in a Bosch dishwasher often indicates a blockage or breakdown of individual elements of the drain system. It can be a filter, a circulation pump, a hose or other parts. Sometimes the real reason is related to the control module, which can suffer from power surges. How to accurately diagnose a violation, and how to carry out an independent repair, is described in this article.

Causes and methods of self-elimination
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. The message appears on the display and is permanently lit. Another sign is the light with the faucet icon on. In this case, the device does not respond to requests and stops working.
If an E24 error occurs in a Bosch dishwasher, most often this indicates a problem with the drain system. For new models, such a message lights up almost immediately after launch, since the unit tests all systems in advance. For older devices, it may only appear at the end of the cycle.
The main reasons that you can eliminate yourself are:
- When the Bosch dishwasher showed the E24 error, this indicates a problem with the filters - they are clogged and can no longer drain water normally. Normally the filters should be cleaned after each cycle. If a corresponding code occurs, the device is disconnected from the mains and the filter is checked, washed under running water.
- Error E24 of a Bosch dishwasher can also indicate an electronics failure. Especially often such cases are observed after a sharp voltage drop in the network. Then it is recommended to remove the plug from the socket, wait 15 minutes, then reconnect and check how the device will work.
- Also, a similar code may 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 eliminate creases. In extreme cases, it is better to replace it.
Other reasons
If all the reasons described do not fit, the Bosch dishwasher error E24 indicates more serious breakdowns. In the cases described below, it is recommended to contact the wizard.
Blockage in the drain system
If the filter is clean enough, and it is impossible to determine the place of clogging, it is necessary to disassemble and inspect each element:
- snail;
- pipe branch;
- drain pump;
- hose leading to the pipe;
- connection to the sewer.
The tap is preliminarily closed, the unit is moved aside, the panel is removed from the back and top, and the repair begins. If any parts are badly worn, it is better to replace them.
Breakage or clogging of the circulation pump
When the Bosch dishwasher shows error E24, this may also indicate the wear of the circulation pump. It consists of a motor and an impeller, by rotating 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 casing of this pump, which will cause it to turn much worse. Inspection and replacement of the part will be required.
But if the pump itself is in order, and at the same time error E 24 of the Bosch dishwasher appears, this may also indicate a clogged part. If the filters are not of good quality, food residues get 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.
Fault in the control module
The dishwasher also gives an E24 error due to a malfunction in the electronics. On the board that is built into the device, the contacts may burn or oxidize due to moisture ingress, as well as due to power surges. In this case, the repair comes 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 drain 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, while draining the waste fluid, you can open and close the chamber door. Then the code disappears from the screen, and the model continues to work in the same mode. However, it is worth remembering that this solution is temporary. Therefore, if the repair could not be done by hand, it is recommended to immediately contact a specialist.
