What LED1:1 LED2:1 LED3:0 LED4:0 LED5:0 means on a Haier dishwasher

The LED1:1 LED2:1 LED3:0 LED4:0 LED5:0 error code on a Haier dishwasher indicates a water supply fault, meaning the appliance is not receiving an adequate or timely flow of water at the start of or during a wash cycle. The LED display pattern is how this particular Haier model communicates diagnostic states in the absence of a numeric readout, with the combination of illuminated and extinguished LEDs pointing to a specific fault category. In this case, the fault is rooted in the water inlet system, which includes the household water supply line, the inlet hose, and the water inlet valve.

The dishwasher's control board monitors water intake through a pressure switch or flow sensor. When the expected water level is not reached within a set time window, the board registers the condition as a water supply failure and halts the cycle to prevent dry operation, which could damage the wash pump and heating element. The most upstream cause to check is always whether the household stopcock supplying the dishwasher is fully open and whether water is physically flowing through the inlet hose.

If the water supply itself is confirmed to be on and flowing, the fault can often be traced to a kinked or blocked inlet hose restricting flow, a clogged inlet hose filter screen where the hose connects to the dishwasher, or a faulty water inlet solenoid valve that is not opening on command. Sediment and mineral buildup are frequent contributors to both screen blockages and valve failures, particularly in hard water areas.

Common causes of LED1:1 LED2:1 LED3:0 LED4:0 LED5:0

  1. 01

    Stopcock turned off or partially closed

    Wiring / connection

    The water supply valve under the sink or behind the dishwasher may be fully or partially closed, preventing water from entering the appliance. Check that it is turned fully counterclockwise to the open position.

  2. 02

    Kinked or blocked inlet hose

    Wiring / connection

    The inlet hose running from the water supply to the dishwasher may be kinked, pinched, or internally obstructed, reducing or stopping water flow. Inspect the full length of the hose and straighten any bends.

  3. 03

    Clogged inlet hose filter screen

    Wiring / connection

    A fine mesh filter screen sits at the connection point between the inlet hose and the dishwasher body, and it can become blocked with sediment or mineral deposits over time. Remove the hose from the appliance and clean the screen under running water.

  4. 04

    Faulty water inlet solenoid valve

    Part replacement

    The inlet valve uses an electrical solenoid to open and allow water in when commanded by the control board. If the solenoid coil has failed or the valve body is stuck shut due to scale buildup, water will not enter regardless of supply pressure.

  5. 05

    Low household water pressure

    Wiring / connection

    Dishwashers require a minimum inlet water pressure to fill correctly within the control board's timing window. If pressure in the home is unusually low due to supply issues or other appliances running simultaneously, the dishwasher may trigger this fault.

Frequently asked questions about LED1:1 LED2:1 LED3:0 LED4:0 LED5:0

What does LED1:1 LED2:1 LED3:0 LED4:0 LED5:0 mean on a Haier dishwasher?
This LED pattern indicates a water supply fault, meaning the dishwasher is not receiving water properly. The control board detected that the appliance did not fill with water as expected within the required time. The issue can range from a simple closed stopcock to a failed water inlet valve.
How do I fix the water supply error on my Haier dishwasher?
Start by confirming the water supply stopcock is fully open and that water flows freely through the inlet hose. Check the hose for kinks and remove it from the dishwasher to inspect and clean the filter screen at the connection point. If those steps do not resolve the issue, the water inlet solenoid valve may need to be tested and replaced.
Will resetting the dishwasher clear this error code?
A reset may clear the displayed error and allow a new cycle to start, but the fault will return if the underlying water supply problem has not been corrected. Address the root cause first, then reset the machine by canceling the current cycle or cycling the power. Running a cycle after fixing the supply issue will confirm the fault is resolved.
Is it safe to use my Haier dishwasher while this error is showing?
You should not attempt to run a wash cycle while this error is active. The dishwasher has stopped the cycle specifically to prevent the pump and heating element from operating without water, which could cause damage to internal components. Resolve the water supply issue before restarting the appliance.
How much will it cost to repair a water supply fault on a Haier dishwasher?
If the fix involves only adjusting the stopcock, clearing a kinked hose, or cleaning the inlet filter screen, there is no parts cost and only your time is involved. If the water inlet solenoid valve needs replacement, parts typically range from $20 to $60 depending on the model, with professional labor adding $80 to $150 on top of that.
