Common Symptoms & Causes

The following symptoms typically appear when your Miele G4998SCViSF is triggering the I10 water inlet error.

• The dishwasher display shows the I10 error code at the start of or during a wash cycle
• The dishwasher fails to fill with water and stops mid-cycle
• You hear the drain pump running continuously without water entering the tub
• The dishwasher door feels warm but the cycle never properly begins

This error is most commonly caused by a kinked or blocked inlet hose, a faulty water inlet valve, low household water pressure, or a clogged inlet filter screen that has worn out over time.

Safety First

• Unplug the dishwasher from the power outlet before starting any repair — never work on a live appliance.
• Shut off the water supply valve before disconnecting any water lines or hoses.
• Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
• Take photos with your phone before disconnecting any wiring harnesses or connectors.
• Work in a well-lit area with enough floor space to lay removed panels flat.

Essential Tools

Step-by-Step Repair Instructions

Step 1

Disconnect power at the breaker or unplug the unit, then shut the water supply valve under the sink to prevent flooding during inspection. Pull the dishwasher forward slightly by loosening the two mounting screws under the counter lip — this gives you access to the inlet hose and valve at the rear. Safety note: never skip the water shutoff; the aqua-stop hose holds pressure even when the machine is off.

Step 2

Disconnect the inlet hose at the back of the unit and inspect the aqua-stop coupling — Miele’s proprietary hose has a built-in leak-protection mechanism that physically shuts off water flow if it detects a leak. If the red indicator on the hose coupling is visible or the float inside has tripped, the hose will not allow water through regardless of whether the valve or fill system is functional, making this a common misdiagnosed fault. A tripped aqua-stop cannot be reset; the entire hose assembly must be replaced.

Step 3

Remove the bottom access panel and locate the inlet valve at the left rear, secured by two Phillips screws. Disconnect the solenoid wires and test resistance across the solenoid terminals with a multimeter set to Rx1 — a healthy solenoid reads 200–500Ω, while an open reading (OL or infinite) confirms the solenoid has failed and the valve must be replaced. Pro tip: also check that the wiring harness connector seats firmly on the valve, as vibration can cause intermittent contact that mimics a valve failure.

Step 4

With the inlet hose disconnected, use needle-nose pliers to carefully extract the fine mesh filter screen from inside the inlet port on the dishwasher. This screen catches sediment and mineral deposits before they reach the valve, and in hard-water areas it can clog completely, starving the machine of water flow and triggering the I10 error even when the valve itself is fully functional. Rinse the screen under running water and use a soft brush to clear mineral buildup; if the mesh is torn or corroded, replace it rather than reinstalling it.

Step 5

Reinstall the filter screen, reconnect the inlet hose securely, then restore the water supply slowly and check the hose coupling for any drips before restoring power. Run a Normal cycle and monitor the machine through the initial fill phase — if the tub fills to the correct level, the I10 error will clear automatically and the cycle will proceed. Pro tip: watch the fill for at least 90 seconds before walking away, as a slow drip at the hose fitting may only appear under sustained pressure.

Step 6

Miele recommends replacing the aqua-stop hose every 10 years as a preventive measure, because the internal leak-protection mechanism degrades with age and can trip spontaneously even without an actual leak. If the hose on your unit is approaching or past that age, replace it now while the machine is already pulled out — the part is inexpensive relative to the labor of a repeat service call. Always use a genuine Miele aqua-stop hose, as aftermarket hoses may not meet the pressure and safety ratings required by the machine’s flood-protection system.

When to Call a Professional

If the issue persists after completing all steps above, the problem may involve the sealed refrigerant system, a failed main control board, or wiring that requires specialized diagnostic equipment. Contact a licensed appliance technician — attempting sealed-system repairs without EPA 608 certification is illegal and unsafe.

“` ## Frequently Asked Questions

What causes the I10 water inlet error on my Miele G4998SCViSF?

The I10 error typically means your dishwasher isn’t receiving enough water, usually due to a kinked supply hose, a closed shut-off valve, or a clogged inlet filter screen. Check these simple issues before assuming a major component has failed.

Can I fix the I10 error myself without calling a technician?

Many I10 errors are resolved by cleaning the inlet filter or straightening the water hose, both tasks a homeowner can do without special tools. However, if the water inlet valve itself is faulty, replacement may require a professional.

How do I reset the I10 error after completing the repair?

Once you’ve fixed the underlying issue, simply turn the dishwasher off, wait 30 seconds, and restart a normal cycle. The error should clear automatically once the machine detects proper water flow.
