Electrolux Dishwasher Error Code Er 05

Er 05 means the control board did not receive a proper speed feedback signal from the upper fan during the drying cycle. The dishwasher uses this fan to circulate warm air for drying, and it monitors the fan's speed to confirm it is operating correctly. When the signal is missing or out of range, the appliance logs this error code. The drying cycle may be interrupted as a result.

The wash and rinse cycles may still function, but the drying performance will be compromised or non-functional while the fault is active. Using the dishwasher in this state is generally not a safety hazard, but continuing to run it without addressing the underlying cause can put additional strain on related components. It is best to diagnose and resolve the error promptly.

A reset may temporarily clear the error code, but if the underlying fault with the fan or its wiring is still present, the code will return once the drying cycle runs again. Resetting is useful for confirming whether the fault is intermittent or consistent, but it is not a permanent fix. The fan system should be inspected and repaired to resolve the error for good.

Some causes of Er 05 are DIY-friendly, such as clearing a physical obstruction from the fan blade or reseating a loose wiring connector. However, replacing the fan motor or control board requires comfort working with appliance electrical components and disassembly of the door or interior panels. If you are not experienced with appliance repair, a qualified technician is recommended for those steps.

Repair costs vary depending on the root cause. If only a wiring connector needs reseating or cleaning, there may be no parts cost involved, though a service call fee typically ranges from $75 to $150. A replacement upper fan motor generally costs between $40 and $120 in parts, while a new control board can range from $150 to $350 or more, plus labor.
