Step-by-step troubleshooting
Check Water Supply Valve
Do: Locate the water supply valve under the sink and ensure it is fully open.
Observe: Water should flow freely when the valve is open.
Means: If the valve is closed or partially closed, opening it may resolve the issue.
Next: If the valve is open and the error persists, move to the next step.
Inspect Inlet Filter
Do: Remove the inlet filter from the water supply line and check for debris or blockages.
Observe: The filter should be clean and free of sediment.
Means: A clogged filter can restrict water flow, causing the E25 error.
Next: If the filter is clean, proceed to the next step.
Test Water Inlet Valve
Do: Use a multimeter to test the water inlet valve for continuity.
Observe: The multimeter should show a reading between 3,000 and 5,000 ohms.
Means: If the valve is not receiving power or has no continuity, it may need to be replaced.
Next: If the valve is faulty, replace it. If it works, continue to the next step.
Check for Kinked Hoses
Do: Inspect the water supply hose for kinks or bends that could restrict water flow.
Observe: The hose should be straight and free of obstructions.
Means: A kinked hose can prevent water from reaching the dishwasher.
Next: If the hose is clear, move on to the next step.
Verify Water Pressure
Do: Check the water pressure using a pressure gauge attached to a nearby faucet.
Observe: Water pressure should be between 20 and 120 psi.
Means: Low water pressure can cause the E25 error.
Next: If the pressure is low, contact your water provider. If it's adequate, continue.
Inspect Dishwasher Connections
Do: Check the connections between the water inlet valve and the dishwasher for leaks or loose fittings.
Observe: Connections should be tight and free of leaks.
Means: Loose connections can lead to water flow issues.
Next: If connections are secure, the issue may be internal and require professional help.
Run a Diagnostic Cycle
Do: Consult your dishwasher's manual to run a diagnostic cycle and see if the error persists.
Observe: The error code should not reappear if the issue is resolved.
Means: If the error still appears, there may be a more serious internal issue.
Next: If the error remains, consider calling a professional technician.
Common causes table
| Cause | Why | Likelihood | Difficulty | Part often needed |
|---|---|---|---|---|
| Closed or partially closed water supply valve | Restricts water flow to the dishwasher | High | Low | No |
| Clogged inlet filter | Blocks water from entering the dishwasher | Medium | Low | No |
| Faulty water inlet valve | Fails to open and allow water into the dishwasher | High | Medium | Yes |
| Kinked or damaged water supply hose | Limits water flow to the appliance | Medium | Low | Yes |
| Low water pressure | Insufficient pressure to fill the dishwasher | Medium | Low | No |
| Loose or leaking connections | Causes water flow issues or leaks | Low | Low | No |
| Internal dishwasher malfunction | Electronic or mechanical failure within the unit | Low | High | Yes |
Parts matching
