Quite often draining does not to work in the washing machine during washing. Also, the appliance might fail before spinning of laundry. Despite the fact that the mistake is common, many users do not know what could be its cause. In some cases, you can eliminate the problem by yourself. Thus, the F03 or F18 error code may appear on the Bosch washing machine display.
What does the F03 error code mean in the Bosch washing machine by MyApplianceRepairHouston.COM
This error indicates a malfunction of the water draining system. The water in the tank does not go down to level 1 in the allotted time zone.
The reasons for F03 error code:
- There is a poor contact at the terminals of the bilge pump. To solve the problem, tighten clamps and clean terminals.
- The bilge pump is defective. It is necessary to clean the filter of the pump of the washing machine or to replace it.
- Problems with drain hose. To fix the breakage, clean the hose from dirt and eliminate bends. Also, set the part into the position specified in the operating instructions.
- The pressostat of the washing machine is out of order. You have to repair the hydraulic system of the water level sensor or replace the pressure switch.
What Does The F18 Error Code Mean In Bosch Washing Machine by MyApplianceRepairHouston.COM
This error indicates a malfunction of the drainage system. So, the time taken for the drain exceeds the specified terms.
Reasons for the F18 error code appearance:
- There is a malfunction in the bilge pump. Clean the filter or replace the washing machine’s bilge pump.
- There is a lock on the switch of the pressure switch. Inspect the controller board and fix any defects if necessary. Also, you might need to replace the water level controller.
- There is a clogging in the drainage path. To solve the problem, clean the drain hose, another drainage pipeline.
Other possible breakdowns and problems affecting the discharge of water from the washing machine are described in detail below.
Breakdown of electronics
One of the most common reasons for the lack of a drain is software failure. To get rid of breakage, you need:
- wait for a while;
- switch on the washing machine;
- run the necessary program again.
If all the performed actions do not have the desired effect, it is best to cancel the running program. Also, you can run a rinse mode followed by laundry spinning and water draining. If after that the washer does not start draining the water, the electronic control module most likely failed.
It is almost impossible to replace it at home. So, that is why you will have to contact specialists.
Why does not draining work in the washing machine? Often the reason for this can be the formation of a blockage in the filter. During the filter functionating various debris and deposits accumulate on branch pipes of the drainage system. Threads, pile, foreign objects, and corrosion are formed from low-quality water. All these items remain on the filter and create an impassable barrier to water.
Garbage accumulation is the most common cause of problems with draining. If this error occurs, a numeric code appears on the dashboard of the washing machine.
To eliminate the trouble, it will be enough to thoroughly clean the filter. It is located behind a small panel at the bottom of the case.
Clogging of nozzles
The drain hoses are an important part of the whole system. They control the distribution of water. In addition, they and prevent it from pouring out of the tank of the machine during operation. The hose is directly connected to the sewer so that the upper end exceeds the level of the drain tank. Incorrect hose installation can also cause failure during water draining. In such situation, the unit will generate an appropriate error code.
Make sure that hoses are not bent and are placed in the normal position. Incorrect configuration of the nozzles can cause leaks. In addition, water gets to electronic components and subsequent closing.
Overlapping the pump impeller with a large object
The debris caught on the pump impeller can lock the mechanism by stopping the part’s rotation. Even a small object can disrupt the operation of this unit, thus preventing the drainage of water. Removing a foreign object is easy. It is enough to remove the filter and get rid of the unwanted formation with tweezers. It is very important to remove the blockage from the system in time. It prevents the appliance from breaking.
Siphon or sewerage clogging
The cause of the breakdown does not always lie in the washing machine. Devices of the Bosch brand are very sensitive to a blockage in the sewage system. If there is a lot of debris, solid objects or deposits near the drain hose, the appliance can cancel the drain program and fail. Only by eliminating blockages in the sewer, you can continue washing.
What to do if the washing machine cancels the drain program and makes unpleasant sounds during operation? This is a sure sign of pump failure. Like a filter, it can be clogged with various garbage that interferes its operation. To clean the pump, you have to remove and completely disassemble it. Next, you need to clean the shaft from the accumulated threads and villi.
If the pump has been in operation for more than three years, it is better to replace it with a new one.
If none of the above methods helps, then it may be worth checking the integrity of the wires and contacts. As a rule, the electronic component of the machine is reliably isolated from water. But over time they might be damaged or worn out. This happens as a result of improper installation or factory defects.
Issues caused by a wire fault:
- incorrect operation of electronics;
- no response to button pressing;
- hanging when switching programs;
- danger of short circuit;
- spontaneous shutdown.
After completing the repair and assembling the washing machine, do the next. You should check all the connections and electronic parts, required for cleaning or debugging. Carefully inspect each wire and hose connected to the pump. Run a test run in each wash mode.
