Is your Bosch dishwasher displaying the 'E15' error code on its LCD screen? This could mean one of several things. Here, we explore the five most common causes of this problem and how to address each one so you can get your dishwasher back up and running again.
One of the most common causes of the E15 error code in Bosch dishwashers is a blocked drainage system. It’s possible for debris or other items to become lodged in the pipes leading from your dishwasher, causing blockages and preventing water from draining away properly. If this is the cause of your issue, you’ll need to access and clean out the drain area of your dishwasher before the problem can be fixed.
If you’ve already checked the drain area for blockages, but the issue persists, then it may be caused by a problem with the internal pump. In this case, it's best to call a qualified appliance repair technician as they should be able to check and diagnose the problem in no time by using their specialized tools and know-how.
Another possibility is that the control board in your dishwasher has become faulty. This is a part that controls all the electrical pins and functions within the dishwasher and it can fail to work properly if it has become loose or corroded. If this is the cause, you’ll need to replace the control board in order to get your dishwasher back up and running.
Blockages in the supply line pump can cause an E15 error code to appear. This part is responsible for discharging water from the dishwasher and if it’s blocked or leaking, it will prevent the unit from starting correctly. To address this, inspect the pump for any visible blockages or check for signs of a leak before replacing the part if required.
Additionally, the surrounding gaskets and related hoses can become clogged with food debris and over time. Check for any blockages around these parts, as well as the inlet valve filter on the side of the dishwasher. To clean, simply remove any visible accumulations of food and rinse thoroughly with water. If any parts show signs of wear or damage then they should be replaced before attempting to restart your dishwasher.
The pressure switch is another part that can cause the 'E15' error in Bosch dishwashers. This switch is designed to detect changes in water pressure and can become faulty over time, leading to the error code. To check if this part is causing the problem, unplug the unit and manually activate the switch before reconnecting the appliance to see if it resolves the issue. If not, replace the pressure switch assembly as required.
To replace the pressure switch assembly, first you must access the unit by removing any panels or shared internal components that are blocking the area. Then, unplug any wiring attached to the old switch and remove it from its mounting clips before installing the replacement part. Once all of the wires have been reconnected, test your Bosch dishwasher again to ensure that the E15 error has been corrected.
The water filling valve is one of the main components that could be responsible for the 'E15' error. It's possible that it has become clogged or faulty over time, leading to incomplete filling of the appliance and triggering the error code. To troubleshoot this issue, ensure that there isn't any debris or blockages preventing proper water flow into the dishwasher and replace the filling valve as needed.
Additionally, make sure that the water pressure for your dishwasher is set correctly. If the pressure is too low, it can lead to an incomplete filling of the appliance and an error code like 'E15'. Try turning up the water pressure if you experience low flow into your dishwasher, as this could help resolve the underlying issue.
