How to fix Bosch Dishwasher Error E14

Quite often, error E14 in a Bosch dishwasher is interspersed with error E18 preventing the dishwasher from working. This problem is so widespread that we decided to disassemble it in as much detail as possible, giving it a whole article. What are the causes of the E14 error, what kind of breakdowns give rise to it, what tools and accessories are needed to carry out the repair, and how, finally, do this repair yourself? Let's talk about this in detail.

Which breakdown is to blame?

Many Bosch modern dishwashers have an instantaneous water heater. The machine draws cold water, and then drives it in a small circle through the heater, until it is heated to the desired temperature. But the question arises: how does the electronic brain of the machine know how much water to draw? In the automatic washing machine there is a pressure switch, which is connected to the control module. The Bosch dishwasher has a similar system, only a water flow sensor is installed instead of the pressure switch, and if it breaks, the self-diagnosis system displays error E14.

This happens in about 65% of cases, so wizards first check this sensor. Secondly, the tightness of the entire system is checked. If there is a slight water leak, and the error E14 sparkles on the display, it means that somewhere a crack has formed. In more rare cases, this error is caused by the inlet valve or the control module.

The electrics supplying the aforementioned elements may also turn out to be faulty, so in the third place you should check the circuits connecting the control module with the water flow sensor and the intake valve.

What will be required to eliminate?

No components and tools need to be prepared in advance. At least until you pinpoint what caused the E14 error. In this paragraph, we will provide a list of what you may need so that you are mentally prepared for the costs that you will have to incur and roughly figured out which stores to eat to take everything you need. The final list will depend on the nature of the breakdown, the model of the dishwasher, and the method of troubleshooting you choose.

1. Screwdrivers: flat head, cross head, hexagon.
2. Pliers.
3. New original water flow sensor.
4. New original intake valve.
5. Multimeter.
6. Sealant and electrical tape.

The list is not long at all, however, you need to make sure that the parts you purchase are compatible with your Bosch dishwasher model. It is better to order accessories for the dishwasher directly from the manufacturer, through the official website. So you will not pay extra to resellers and you will definitely get an original, suitable and high-quality part.

Troubleshooting

The water flow sensor, as well as the inlet valve, are located in the pan of the dishwasher. To get to them, you need to disassemble the machine, so to clear our conscience, we will perform a manipulation that can help correct the error E14. What should be done?

1. We disconnect the machine from communications and pull it out to the middle of the room.
2. We put rags under the body so that water does not pour from the pallet onto the floor, if it is there.
3. We tilt the body of the machine first to the right, then to the left, and then back. You need to do this several times.
4. We put the machine in place, connect it and try to run.

Why can error E14 disappear due to these inclinations? It's simple, this simple method allows you to equalize the pressure in the system, and if there are no problems besides this, the machine will work as it should. If the error reappears on the display, it should be recognized that the “focus failed” and you need to think about how to fix the situation. To check the details we are interested in, you should disassemble the Bosch dishwasher.

1. We prepare the machine for disassembly by moving it to a convenient place.
2. We remove the decorative panel of the door, unscrew the front plate located under the door.
3. We remove the closers from the fasteners, which allow the door to open and close smoothly. After this, the door must be kept open.
4. On the outside of the pallet in the corners are the screws that need to be unscrewed.
5. We roll out the lower large basket from the dishwasher.
6. We remove the lower beam, filter, mesh.
7. Unscrew the screws that were under the net.
8. We throw a few rags at the rear wall of the dishwasher, and then put the machine on them to get better access to the pallet and the parts that are in it.
9. Next, from the pallet, you need to disconnect everything that interferes: chips with wires, water inlet hose, pump and so on.

When disassembling the dishwasher tray, photograph each stage of the work so that later it is easier to return everything back.

10. Now you can gently pull the pallet onto yourself and unhook it from the main body, gaining full access to all necessary details.

The rest is a matter of technology. We measure the resistance of the inlet valve and the water flow sensor with a multimeter and find the weak link. If the details are working, then we check the wiring, perhaps one of the supply wires is frayed. The intake valve and water flow sensor are replaced without tools. We disconnect the chips with wires, unscrew the parts themselves and put new ones in their place, nothing tricky.

It happens that error E14 is interspersed with Bug dishwasher E25. In this case, you still need to additionally check the drain pump nozzle and the pump itself for blockages.

In conclusion, the correction of the E14 error on a modern Bosch dishwasher may require the intervention of a qualified professional. Dismantling an expensive dishwasher is still the lot of professionals, but if you try, you can do it yourself. Save between 40 and 110 dollars. That is how much a master will take from you for repairs without taking into account the cost of parts. Good luck
