Common questions
Quick answers for this fault
What should I check first for IE?
Start with water supply valve closed. If that checks out, continue through the diagnostic sequence above rather than replacing a part based on the code alone.
Does IE always mean Dishwasher Water Inlet Valve is bad?
No. An error code identifies the condition the control detected, not a guaranteed failed part. Confirm the likely causes and wiring first. The exact OEM part number varies by model and production revision. Verify the complete model number before ordering.
When should I stop troubleshooting IE myself?
Stop if the next step requires live electrical testing, sealed-system work, gas or combustion service, or any procedure outside your training. Disconnect electrical power before removing panels or handling internal components. Do not bypass safety devices or perform live electrical testing unless you are qualified to do so.
