Introduction
Bosch dishwasher error codes help you to identify problems quickly, but they can also be confusing if you are unfamiliar with their meaning. This guide explains the common Bosch error codes, their causes, and easy fixes to get your dishwasher working again.
What are dishwasher error codes?
A dishwasher error code is a built-in alert system that shows your appliance has detected a problem. These codes appear as numbers or letters like (E15 or E25) on the display control board. Each code points out specific issues such as leaks, hearing faults, or drainage problems. Understanding these error codes helps you to analyse the problem and decide whether you can fix it by yourself or need professional repair.
This troubleshooting guide refers to the following model numbers:
SHX89PW75N, GM926710,SHE43P25UC/64, SHE45M05UC/50, SHE45M06UC/50, SHV89PW73N ,SHE89PW75N, SHX88PZ65N, SHP88PZ55N, SHEM78ZH5N, SHXM88Z75N, SHPM88Z75N, SHI4306, SHI6802, SHI6805
What should you do when an error code appears?
For most Bosch dishwasher error codes, the recommended steps are:
- Turn off the dishwasher and unplug it.
- Check the water supply, filters, and drainage depending on the error code.
- Do not restart if water leakage or electrical faults are suspected.
- Contact a technician if the issue persists or involves internal components.
It is also important to check for any water collecting in the base tray. If water is present, carefully tilting the dishwasher at a 45-degree angle (when it is switched off) can help it drain out.
Bosch dishwasher error codes
Error code E01
E01 indicates a failure in the main control board, often related to the pump control circuit. A reset may temporarily clear the error, but persistent issues usually require repair or replacement.
Error code E02
E02 indicates a temperature sensor fault, heating element, or possible control board failure. Inspect the sensor wiring and then restart the dishwasher to reset the system.
Error code E03
This E03 error code indicates that the dishwasher is not filling with enough water. Check the water supply, inlet hose, and ensure the tap is fully open.
Error code E04
E04 indicates a water flow sensor fault. Check for blockages in the inlet system and restart the dishwasher if necessary.
Error code E05
E05 indicates the dishwasher has too much water, often due to a faulty float switch. Inspect the float switch and check for water in the base tray.
Error code E06
E06 indicates a door locking issue before the cycle starts. Check the door latch and mechanism for proper closure.
Error code E07
E07 indicates a fault with the Zeolite drying fan. Check for fan obstruction or internal drying system failure.
Error code E08
The cycle was interrupted because the water level dropped unexpectedly. Check for overturned dishes and ensure the water supply is stable.
Error code E09
E09 indicates a heating fault, typically caused by the heater relay or heating element. Check for heating failure; this issue often requires a technician to test and replace components.
Error code E10
E10 indicates a fault in the Zeolite-chamber heating system. The drying heater may be defective and usually requires professional repair due to limited access.
Error code E12
The E12 error code indicates that there is a buildup of lime scale in your dishwasher. Deep cleaning and descaling your dishwasher may resolve the issue.
Error code E14
The flow meter is unable to detect or count water flow pulses accurately. This E14 error code usually indicates a faulty sensor or a disruption in the water flow system.
Error code E15
Water has leaked into the base tray, activating the AquaStop safety system. This E15 error code triggers the dishwasher to stop and prevents further water intake to avoid flooding.
Error code E16
The E16 error code indicates that the inlet valve is not closing properly. This can cause continuous water intake and may indicate a faulty valve or control issue.
Error code E17
rror code E17 shows that the water pressure is too high. This may affect the proper operation of the inlet system and cause irregular filling behavior.
Error code E18
Fill timeout has occurred due to very low water flow. The E18 error code usually indicates a restricted water supply, a clogged inlet filter, or a faulty inlet valve.
Error code E19
The E19 error code indicates a fault has been detected in the heat-exchanger valve.
This may affect water circulation and heating efficiency during the wash cycle.
Error code E20 & E21
A heat-pump internal error or a blocked drain pump has been detected. This can disrupt heating, circulation, or draining during the wash cycle.
Error code E22
This E22 error code indicates that the filter system is blocked. This can restrict water flow and reduce cleaning performance during the cycle.
Error code E23 & E25
In these Error codes, a fault has been detected in the drain pump electronics, or the impeller is jammed. This can prevent proper draining of water from the dishwasher.
Error code E24
Error code E24 indicates that your dishwasher is unable to drain. This is usually caused by a blockage in the drain system, a clogged filter, or a faulty drain pump.
Error code E27
This E27 indicates that the mains voltage is too low. This can disrupt normal operation and cause the dishwasher to pause or stop mid-cycle.
Water tap symbol
The water tap symbol is displayed. This usually indicates an issue with the water supply, such as a closed tap or a blockage in the inlet line. Check that the water tap is fully open and the inlet hose is not kinked or obstructed.
