Electrolux Dishwasher Error Code LD9:on LD10:off LD11:on

This combination of LED indicators signals an NTC sensor error, meaning the dishwasher's water temperature sensor has been detected as either short-circuited or broken. The control board monitors the NTC sensor from the first water fill through the end of the wash phase. When a fault is detected, the machine completes the cycle but disables the heating element entirely, causing all heating phases to run for approximately 45 minutes without any heat.

The dishwasher will complete cycles without the heating element active, so there is no immediate safety hazard from continuing to run it. However, without heated water and a working drying cycle, dishes will not be properly sanitized or dried, which is a hygiene concern. The underlying wiring or sensor fault should be addressed promptly to restore normal operation.

If only the NTC thermistor sensor needs replacement, parts typically range from $15 to $60 depending on the specific model, making it a relatively low-cost repair if done without a service call. If a technician is needed for diagnosis and replacement, the total cost including labor generally falls between $100 and $250. Control board replacement, if required, is significantly more expensive, typically ranging from $200 to $450 or more for parts and labor.

A knowledgeable DIYer can diagnose this fault by inspecting the NTC sensor wiring for damage, checking connector terminals for corrosion, and testing the sensor's resistance with a multimeter. If the sensor itself has failed, replacing it is a straightforward repair that typically involves removing the lower wash arm assembly and sump area to access the sensor. If wiring or connectors are the cause, repairs may only require cleaning terminals or splicing damaged wire sections.

A power reset may temporarily clear the displayed fault, but the error will return as soon as the dishwasher reaches the monitoring window during the next cycle if the NTC sensor or its wiring is still faulty. A reset does not address the root cause, and the heating element will continue to be disabled until the underlying sensor circuit issue is repaired.
