Error code E15 or E24 appears on the display Bosch most often requires immediate access to the sump or drain pump to eliminate a leak or blockage. To begin repairs, you need to remove the side walls or bottom panel, having first disconnected the device from the power supply and water supply. Disassembly dishwasher this brand has its own nuances related to the design of the case and the location of fasteners, so it is important to act consistently.
Before starting work, make sure that there is no water in the chamber and that all baskets and sprinklers have been removed. Improper removal of the panels may damage the plastic latches or cause leaks in the connections. In this manual, we will look at the main dismantling steps to gain access to the key components of the unit.
Tool preparation and safety precautions
Any work with electrical appliances begins with completely de-energizing the device. Unplug the socket or turn off the circuit breaker in the panel to eliminate the risk of electric shock from contact with internal components. It is also necessary to turn off the water supply tap and disconnect the inlet hose, preparing a container to drain the remaining liquid from the system.
For proper disassembly, you will need a set of screwdrivers, including Phillips and flat head screwdrivers, as well as pliers and possibly socket wrenches. Some models Bosch are mounted on torx screws, so the presence of a bit T20 or T25 will not be superfluous. All tools must be in good working order so as not to tear off the fastener heads.
⚠️ Attention: Before tilting or upending the dishwasher, make sure there is no water left in the bottom (drip tray) to avoid spilling the electronic components or flooring.
Organize your workspace so that you have easy access from all sides of the device. It is advisable to place thick cloth or cardboard under the car to avoid scratching the floor and losing small parts that may roll out during dismantling.
☑️ Preparation for disassembly
Removing the top and side panels of the case
Access to internal mechanisms Bosch dishwasher often requires dismantling the top cover, especially if you need to remove the front door or gain access to the top fastenings. To do this, unscrew the two screws located on the back along the top edge of the case. After loosening the fasteners, slide the cover back and lift it up.
The side walls in most models do not have a load-bearing function and serve as a decorative element, but their removal is necessary to replace the circulation pump or motor. The mounting screws are usually located at the back and sometimes at the front, hidden under decorative plugs. Carefully bend the metal hooks, if present, and remove the panel in an upward-outward motion.
- 🔧 Unscrew the screws securing the top cover at the back of the case.
- 🔧 Remove the side wall by bending the fixing tabs.
- 🔧 Remove the sealing tape if it interferes with access to the screws.
- 🔧 Check the integrity of the thermal insulation material on the walls.
When working with metal panels, be careful as the edges of the sheet metal can be sharp. Use gloves to avoid cuts. If the model is built-in, you must first completely remove it from the niche of the kitchen unit by unscrewing the fasteners to the countertop and side walls of the cabinet.
Fastening Features
On some Bosch models, the side panel screws may be hidden under rubber feet or a trim strip at the bottom. Carefully inspect the perimeter of the housing before starting dismantling.
Removing the bottom panel and accessing the tray
The lower part of the housing hides the tray in which it is installed drain pump and float leakage protection system AquaStop. To remove the bottom plastic strip, you often just need to pull it down, as it is held in place by latches. However, in some series it is necessary to unscrew the screws around the perimeter of the base.
After removing the decorative strip, access to the metal base and heat-insulating material opens. To gain full access to the pallet, you must remove the metal plate that is screwed to the bottom frame. This will allow you to see the water level in the pan and visually diagnose the presence of a leak.
| Component | Location | Mounting type | Tool |
|---|---|---|---|
| Bottom bar | Bottom Front | Latches/Screws | Screwdriver |
| Metal bottom | Under isolation | Screws around the perimeter | Phillips screwdriver |
| AquaStop float | In a pallet | On the guides | No tool |
| Drain pump | In the pallet, on the right | Screws / Latches | Pliers |
If water is found in the pan, this indicates a violation of the tightness of the circuit. Before putting the car back together, it is necessary to find and eliminate the cause, otherwise the error E15 will appear again. Scoop out the water with a sponge or rag and dry the tray.
Disassembling the door and replacing the seal
Door Bosch dishwasher consists of an outer panel, an internal plastic tank and an opening mechanism. To remove the inner panel, you need to unscrew the screws around the perimeter, and then carefully unclip the plastic clips. Be careful: there may be wires running inside to control buttons and indicators.
Replacing the sealing rubber is required if puddles appear on the floor after a washing cycle, and the tape itself has lost elasticity or is damaged. The old seal is removed from the groove, and the new one is installed starting from the corners, pressing tightly along the entire perimeter. It is important that the rubber is not stretched or compressed.
⚠️ Attention: When disassembling the door, do not apply excessive force to the plastic latches, as they easily break in the cold or from the old age of the plastic.
The door opening mechanism with cables and weights is located at the bottom. If the door falls or, conversely, does not open, the problem may be a broken cable or worn plastic rollers. To replace these elements, it is often necessary to completely dismantle the side walls and remove the machine from its installation site.
Access to the circulation pump and heating element
The circulation pump is the heart of the dishwasher, creating water pressure for washing. It is located at the bottom of the camera, under the filter. To remove it, you need to turn the car on its side (after removing the lower protection), disconnect the electrical connectors and pipes, and then unscrew the mounting screws.
Heating element (heating element) in Bosch machines is often integrated into the flow-through heater or located separately at the bottom of the tank. If the machine stops heating water and displays an error E09, you will need to check the heating element with a multimeter for a break. Replacing this element is labor-intensive and may require partial disassembly of the housing.
- 🔌 Disconnect the power terminals before checking the heating element.
- 🔌 Check the resistance of the heater (the norm is 20-40 Ohms).
- 🔌 Inspect the pipes for cracks and scale.
- 🔌 Make sure the pump impeller is clean from foreign objects.
When assembling the units, it is important to correctly install the O-rings on the pipes, having previously lubricated them with water or a special lubricant. A distortion of the seal will lead to leakage into the housing and re-activation of the protection system.
Tip: Before installing a new pump, check the drain hose and sewer outlet for blockages to ensure that the new part does not fail due to overload.
AquaStop leak protection system
System AquaStop in dishwashers Bosch It is represented by a double water supply hose and a tray with a float. If water enters the pan, the float rises and mechanically or electrically closes the supply valve. Disassembly of this unit is required in case of false alarms or leaks of the hose itself.
To check the system, you need to remove the top cover and find where the hose enters the machine. The solenoid valve is located there. By disconnecting it, you can check the coil for functionality. It is difficult to change the double-braided hose yourself; it is easier to purchase a ready-made repair kit with a valve.
A common reason for the protection to trip is not an actual leak, but foaming due to the use of an unsuitable detergent. Excessive foam may flow over the edge of the baskets and into the drip pan, lifting the float. In this case, it is enough to dry the tray and change the chemicals.
Key takeaway: Most Bosch dishwasher errors can be resolved by cleaning the filters and checking the drain hose before attempting complex disassembly of the cabinet.
Assembly and initial launch
Assembly is carried out in reverse order. It is important to remember to put all screws in place, especially those that hold the ground and motor. Check that all electrical connectors are clicked into place and that the wires are not pinched by metal parts of the case.
Before plugging in, run a short wash cycle without dishes to check the connections for leaks. Pay close attention to the underside of the machine and hose connections. If moisture appears, stop the program immediately and correct the leak.
Make sure the machine is level. Adjusting the legs affects the correct operation of the circulation pump and water drainage. Uneven installation may cause water to remain on the bottom and cause an unpleasant odor.
What to do if after disassembly the car makes a louder noise?
An increased hum may indicate that the vibration-isolating element was pinched during assembly or that the pump was installed incorrectly. Also check to see if any wires are touching any rotating parts or the tank itself. Sometimes it is enough to correct the position of the machine according to the level.
How to reset an error after repair?
In most Bosch models, it is enough to turn off the machine with the button and turn off the power for 10-15 minutes. To completely reset errors, you can use a combination of buttons (usually holding the Start button and selecting a program), but the exact code depends on the device series.
Can filters be washed in the dishwasher?
No, filters should only be cleaned under running water using a soft brush. Washing the filters inside the dishwasher can cause small debris to clog the pump and food debris to stick to the walls of the dishwasher.
