Electrolux Dishwasher Error Code i0 (13 blinks)

The i0 error code, displayed as 13 blinks, means the dishwasher's control board detected no tacho signal from the circulation pump motor for an extended period while the pump was running. The tacho generator is a small speed-sensing component that should measure around 220 ohms. Without its signal, the machine cannot regulate pump speed and disables the heating element as a precaution. The pump will still run, but without proper speed control.

A reset may temporarily clear the error code, but the fault will return if the underlying problem with the tacho generator, wiring, or pump motor has not been corrected. The control board re-checks the tacho signal at every program step, so the error will reappear as soon as the pump runs without a valid signal. A reset is useful for confirming whether the issue is intermittent, but it is not a fix.

Repair costs depend on which component has failed. A tacho generator or wiring repair is typically the least expensive path, with parts generally ranging from around $15 to $60 depending on the model. If the full circulation pump motor requires replacement, parts costs are usually in the $80 to $200 range. Adding a professional technician's labor will bring total repair costs higher, commonly in the $150 to $350 range for a pump-related repair.

A knowledgeable DIYer can perform basic diagnostics such as checking the tacho generator's resistance with a multimeter, inspecting wiring connectors, and looking for visible damage to the harness. If the tacho generator reads far from 220 ohms or shows an open circuit, replacing it is a practical repair for someone comfortable working with appliance wiring. If the wiring and tacho test correctly, the fault may lie with the circulation pump motor or control board, which are more involved repairs.

The dishwasher will continue to operate with the i0 error, but heating is disabled, meaning your dishes will not be washed in heated water and sanitization will be compromised. Running the machine repeatedly in this condition also places unregulated stress on the circulation pump motor since speed control is lost. It is advisable to diagnose and correct the fault before continuing regular use.
