Haier Dishwasher Error Code LED1:1 LED2:1 LED3:1 LED4:0 LED5:0

This LED pattern signals a water overflow condition in the bottom case of the dishwasher. The unit has detected water in its base drip tray via the overflow float switch and has stopped operation to prevent further leakage. The dishwasher will not resume a wash cycle until the root cause of the water accumulation is identified and corrected, and the switch resets.

No, you should not operate the dishwasher while this error is active. Water in the base tray can reach electrical components and wiring, creating a shock or short-circuit risk. The dishwasher's control system disables the unit for this reason, and running it before the leak source is repaired could worsen the damage.

Repair costs vary widely depending on the cause. Replacing a door gasket typically falls in the range of $20 to $80 for parts, while a new overflow switch generally costs $15 to $50. If the pump seal or pump assembly requires replacement, parts and labor costs can range from $100 to $250 or more depending on the service provider and local rates.

Start by carefully tilting the front of the dishwasher upward slightly to drain any water from the base tray, then set the unit level and allow it to dry completely. Next, inspect the door gasket, all internal hoses, and the pump area for signs of leaking. If the tray is dry and the error persists, the overflow switch itself may be stuck and will need to be tested and potentially replaced.

A power reset alone will typically not permanently clear this error if water remains in the base tray or the overflow switch is still activated. The switch must physically reset to its resting position, which only happens once the tray is dry and the float drops back down. Clearing the water and addressing the leak source is required before a reset will hold.
