Ikea Dishwasher Error Code i4

The i4 code on an Ikea dishwasher means a water leak has been detected in the base pan of the appliance. A float switch in the bottom tray rises when water accumulates there and signals the control board to stop the cycle. The most common cause is using the wrong type or too much detergent, though internal leaks from hoses, seals, or the pump are also possible. The machine will not resume normal operation until the source of the water is identified and the base pan is dried.

No, you should not continue running the dishwasher while the i4 error is active. The code indicates water is present in the base pan, and continuing to operate the machine could worsen the leak, damage the motor or electrical components, or create a water damage or slip hazard. Leave the dishwasher off and unplugged while you investigate the source of the leak.

Repair costs vary widely depending on the cause. If the issue is simply incorrect detergent, there is no parts cost at all. Replacing a door gasket typically runs in the range of $20 to $60 for the part, with additional labor if a technician is hired. Pump seal or hose repairs can range from $50 to $200 or more depending on parts availability and labor rates in your area. Getting a professional diagnosis first can help you decide whether repair or replacement is the more cost-effective choice.

Start by confirming you are using a low-foaming detergent made specifically for automatic dishwashers and that you are not overfilling the dispenser. If the detergent is correct, remove the lower access panel and inspect all hoses, the pump housing, and the door gasket for signs of a leak. Dry out any water from the base pan completely, then run a short cycle while watching for where the water originates. Depending on the source, the fix may be as simple as reseating a hose clamp or as involved as replacing a door seal or pump.

A simple reset will not permanently clear the i4 error if water remains in the base pan or if the underlying leak has not been resolved. The float switch will continue to detect the moisture and re-trigger the code. You must dry the base pan completely and address the root cause before the error will stay cleared. In some cases, carefully tilting the appliance forward allows residual water to drain out, which can release the float switch.
