Electrolux Dishwasher Error Code LD9+LD11 lit permanently

This fault code indicates a tacho error, meaning the control board received no tachometer signal from the recycling pump motor for 30 seconds while the pump was commanded to run. The tachometer is a sensor that confirms the pump motor is actually rotating. When this signal is absent, the dishwasher halts the program, supplies water up to the pressostat function point, and waits for the operator to press the ON/OFF key (S0) to restart.

No, you should not continue running the dishwasher while this fault is active. The error indicates the recycling pump motor is not confirmed to be operating correctly, which means dishes will not be cleaned and the pump could be at risk of damage if run without proper circulation. The machine will interrupt operation automatically, but repeated restart attempts without fixing the cause can worsen the underlying fault.

Repair costs vary depending on the failed component. A wiring repair or sensor replacement is typically the least expensive option, while a full pump motor assembly replacement or control board replacement will cost more. Parts and labor combined can range from roughly $80 to $350 or more depending on the specific component needed and local labor rates. Getting a diagnosis before committing to repair helps determine whether the fix is economical relative to the age of the appliance.

Some causes are DIY-accessible, such as clearing a jammed pump impeller or reconnecting a loose wiring harness connector. However, replacing a failed pump motor, tacho sensor, or control board requires disassembly of the appliance and a basic ability to test components with a multimeter. If you are not comfortable working with appliance wiring or internal components, a qualified technician should perform the diagnosis and repair.

Pressing the ON/OFF key (S0) will restart the dishwasher and clear the displayed fault, but the error will return if the root cause has not been resolved. A reset is the required first step to get the machine running again, but it is not a repair. The tacho sensor, pump motor, wiring, or control board must be inspected and repaired or replaced to permanently clear the fault.
