Answer to continue safely
Is it safe to keep using?
No. Without sufficient water, the dishwasher cannot clean dishes and the spray arms may run dry, potentially damaging the wash pump. Do not continue running cycles until the fill issue is resolved.
Can I reset the code?
Yes. Press and hold Start/Cancel for 3 seconds or turn off the breaker for 60 seconds. If the water supply issue is resolved, the code will not return. If the problem persists, i40 will reappear during the next fill attempt.
When to stop immediately?
Stop if you notice: The supply valve is fully open but no water enters the dishwasher at all, The inlet hose or valve connection is leaking when the valve is opened.
Symptoms You May Notice
Dishwasher stops shortly after starting
The machine begins a cycle but halts within the first few minutes, displaying i40, because insufficient water has entered the tub during the fill phase.
No water sound during fill phase
The typical rushing or trickling sound of water entering the tub is absent, and the machine sits quietly before triggering the error.
Very low water level visible in the tub
Opening the door reveals barely any water at the bottom of the tub, far less than the normal level needed to submerge the spray arm hub.
Code reappears after each reset
Restarting the cycle results in the same i40 error because the underlying water supply issue has not been resolved.
Possible Causes
Closed or restricted supply valve
The shut-off valve under the sink is not fully open or is partially obstructed, reducing the water flow rate below what the dishwasher requires.
DIY PossibleClogged inlet filter screen
Sediment and mineral deposits have accumulated on the fine mesh screen at the water inlet connection, restricting water flow into the machine.
DIY PossibleFaulty water inlet valve
The solenoid valve that controls water entry has failed electrically or is mechanically stuck closed, preventing water from entering the tub even when supply pressure is adequate.
Requires ProfessionalSafe Checks You Can Do
-
1
Verify water supply is open
Locate the water shut-off valve under the kitchen sink that feeds the dishwasher. Turn it fully counterclockwise to ensure it is completely open. Run the kitchen faucet to confirm normal water pressure.
If you have a quarter-turn ball valve, the handle should be parallel to the pipe when open.

2
Clean the inlet filter screen
Turn off the supply valve. Disconnect the water inlet hose from the back of the dishwasher. Remove the small mesh filter with pliers and rinse it under running water to remove sediment. Reinstall and reconnect.
Have a towel ready to catch residual water when you disconnect the hose.
Tools required -
3
Reset and run a test cycle
Restore the water supply, close the dishwasher door, and start a short wash cycle. Listen for the sound of water entering the machine within the first 90 seconds.
Press Start/Cancel for 3 seconds first to clear the previous fault before starting a new cycle.
When to Call a Professional
Contact a qualified technician if:
- Water pressure at the supply is normal but the inlet valve does not click open when the cycle begins
- The inlet valve solenoid has visible burn marks or corrosion on its electrical connector
- A multimeter reading across the valve solenoid shows open-circuit or out-of-specification resistance
