Step-by-step troubleshooting

Check Water Supply
Do: Verify the water supply valve is fully open and the house water is on.
Observe: Water should flow freely to the dishwasher inlet.
Means: If no water flows, the issue is with the home's water supply or the supply line.
Next: Check the water inlet valve if the supply is on.
Inspect Water Inlet Valve
Do: Locate the water inlet valve and check for clogs or damage.
Observe: Debris or a faulty valve can block water flow.
Means: A clogged or faulty valve is a common cause of error E22.
Next: Test the water inlet valve with a multimeter.
Test Water Inlet Valve
Do: Use a multimeter to test the valve for continuity.
Observe: No continuity means the valve is faulty and needs replacement.
Means: A faulty valve prevents water from entering the dishwasher.
Next: Replace the water inlet valve if it's faulty.
Check Water Inlet Hose
Do: Inspect the hose for kinks, cracks, or blockages.
Observe: A damaged or kinked hose restricts water flow.
Means: Replace the hose if it's damaged or clear any blockages.
Next: Reconnect the hose and restore water supply.
Verify Dishwasher Door Seal
Do: Check the door seal for leaks or damage.
Observe: A faulty seal may cause the dishwasher to not recognize the door is closed.
Means: A damaged seal can lead to operational issues.
Next: Replace the door seal if necessary.
Reset the Dishwasher
Do: Unplug the dishwasher for 1–2 minutes, then plug it back in.
Observe: The error may reset and clear.
Means: A power reset can resolve temporary glitches.
Next: Run a test cycle to see if the error returns.
