      🔧 Step 1: Test water inlet valve solenoids with multimeter

      1. Turn off the circuit breaker controlling the dishwasher at your electrical panel.
      2. Turn off the water supply valve located under the sink, typically 12-18 inches from the floor on the hot water line.
      3. Open the dishwasher door and remove the lower dish rack by lifting it straight up and out.
      4. Remove the spray arm by turning it counterclockwise and lifting it off the center mount.
      5. Remove the filter assembly by twisting the cylindrical filter counterclockwise 1/4 turn and lifting out, then lifting the flat fine filter.
      6. Use a T20 Torx bit to remove the 8 screws securing the toe kick panel at the bottom front of the dishwasher.
      7. Pull the toe kick panel forward to remove it completely.
      8. Locate the water inlet valve on the left side of the dishwasher base, approximately 4 inches from the front edge – it’s a brass-colored component with two solenoid coils on top covered by black plastic housings.
      9. Trace the two wires (typically brown and blue) from each solenoid coil back to their spade connector terminals on top of the valve body.
      10. Pull each spade connector straight off the solenoid terminals.
      11. Set your digital multimeter to the ohms (Ω) setting at 200 ohms range.
      12. Touch one multimeter probe to each terminal on the first solenoid coil.
      13. Read the resistance value – you should see between 500-1500 ohms (typically around 1000 ohms). An open circuit (OL or infinite reading) indicates a failed solenoid.
      14. Repeat steps 12-13 for the second solenoid coil.
      15. If either solenoid reads outside the 500-1500 ohm range or shows an open circuit, the inlet valve assembly requires replacement (Miele part number 10634890).

      🛠️ Step 2: Check valve for sediment buildup

      1. Locate the inlet valve at the bottom left corner of the dishwasher, approximately 3 inches from the left side panel and 2 inches from the front edge.
      2. Place a shallow pan or towels under the valve area to catch residual water (expect 1-2 cups).
      3. Use an adjustable wrench to disconnect the water supply line from the inlet valve by turning the compression nut counterclockwise 8-10 full rotations until free.
      4. Look inside the valve inlet port—you’ll see a small cylindrical screen filter (approximately 1 inch diameter) seated inside the valve body.
      5. Use needle-nose pliers to grip the plastic rim of the screen filter and pull straight out with steady pressure—it should release after applying 2-3 pounds of force.
      6. Hold the screen filter under bright light and examine both sides—sediment appears as white, brown, or rust-colored deposits blocking the mesh openings.
      7. If sediment is present, soak the screen in a bowl containing equal parts white vinegar and warm water for 15 minutes.
      8. Use a soft-bristled toothbrush to scrub both sides of the screen in circular motions, working from the center outward, for 30-45 seconds per side.
      9. Rinse the screen under running tap water while holding it up to light—you should see light passing through all mesh openings uniformly.
      10. Inspect the valve body inlet port using a flashlight—look for debris or mineral buildup around the rubber gasket seat (a black O-ring visible 1/4 inch inside the port).
      11. Wipe the valve body interior with a damp cloth wrapped around your index finger, rotating clockwise to remove any loose particles.
      12. Push the cleaned screen filter back into the valve inlet port until it sits flush with the valve body opening—no gap should be visible around the edges.
      13. Reconnect the water supply line, hand-tightening the compression nut clockwise, then use the adjustable wrench to turn an additional 1/4 turn (90 degrees) past hand-tight.

      ⚙️ Step 3: Inspect valve screen for clogs

      1. Locate the inlet valve where the water supply line connects at the lower left corner of the dishwasher cabinet when viewed from the front.
      2. Grip the water inlet hose connection (the ribbed metal nut where your supply line attaches) and rotate counterclockwise using a 3/4-inch adjustable wrench to disconnect it from the valve body.
      3. Look inside the threaded inlet port on the valve body – you’ll see a small cylindrical mesh screen (approximately 1/2 inch diameter) sitting just inside the threaded opening.
      4. Insert needle-nose pliers into the inlet port, grip the outer edge of the screen filter, and pull straight out to remove it. The screen should slide out with light resistance.
      5. Hold the screen under bright light and examine both sides – debris appears as dark spots, mineral deposits look white or chalky, and clean mesh shows light passing through evenly spaced holes.
      6. If debris is present, place the screen in a small bowl filled with equal parts white vinegar and warm water for 15 minutes to dissolve mineral buildup.
      7. After soaking, use an old soft-bristled toothbrush to scrub both sides of the screen in a circular motion for 30 seconds per side.
      8. Rinse the screen under running tap water while holding it up to light – you should see light passing uniformly through all mesh openings with no blocked holes.
      9. Insert the cleaned screen back into the inlet port with the convex (slightly domed) side facing outward toward you, pressing firmly until it sits flush with the edge of the threaded opening.
      10. Reconnect the water supply line by hand-threading it clockwise onto the valve, then tighten with the 3/4-inch wrench a quarter-turn past hand-tight (you’ll feel increased resistance when properly seated).

      🔩 Step 4: Test valve operation

      1. Locate the water inlet valve you’ve just installed or repaired at the bottom left side of the dishwasher, approximately 3 inches from the left edge and 2 inches from the front.
      2. Trace the two-wire electrical connector (blue and brown wires) leading to the valve solenoid coil on top of the valve body.
      3. Set your multimeter to the resistance (Ω) setting at 200 ohms range.
      4. Touch the red multimeter probe to the blue wire terminal and the black probe to the brown wire terminal while the connector is still attached to the valve.
      5. Read the resistance value on the multimeter display—you should see between 3.5 and 4.5 ohms, indicating the solenoid coil is functioning correctly.
      6. Turn the dishwasher’s circuit breaker back on at your electrical panel.
      7. Turn the water supply valve beneath your sink counterclockwise to the fully open position.
      8. Open the dishwasher door and press the “Start/Stop” button for 3 seconds to initiate a drain cycle, then close the door.
      9. After the drain completes (approximately 90 seconds), press “Start/Stop” again for 3 seconds, then immediately press it once more to begin a fill cycle.
      10. Listen for a distinct clicking sound from the valve, followed by water flowing—this occurs within 5-10 seconds of cycle start.
      11. Open the dishwasher door partially (the cycle will pause) and look at the sump area in the center bottom of the tub.
      12. Observe water entering the sump—you should see steady flow creating a pool that reaches approximately 1 inch depth within 60 seconds.
      13. Press “Start/Stop” for 3 seconds to cancel the cycle.
      14. Check for water leaks around the valve inlet connection, the valve body seam, and the outlet hose connection by running your fingers along each junction point and inspecting for moisture.

      đź“‹ Step 5: Replace water inlet valve if solenoids fail or valve is clogged

      1. Turn off the water supply valve completely by rotating it clockwise until it stops (usually located under the sink or behind the dishwasher).
      2. Pull the dishwasher forward approximately 12 inches from the cabinet space to access the bottom panel.
      3. Disconnect the water supply line from the inlet valve using an adjustable wrench or 3/4-inch wrench, turning counterclockwise. Position a shallow pan beneath to catch residual water (expect 1-2 cups).
      4. Locate the inlet valve on the lower left side of the dishwasher base, approximately 4 inches from the front edge and 3 inches from the left side.
      5. Disconnect the electrical connector from the valve by pressing the release tab on top and pulling straight away from the valve body.
      6. Remove the two T20 Torx screws securing the valve bracket to the base frame, located on the left and right sides of the valve assembly.
      7. Disconnect the internal water hose from the valve outlet by loosening the spring clamp with needle-nose pliers, squeezing the clamp tabs together and sliding it back 2 inches along the hose.
      8. Pull the hose straight off the valve outlet nipple with a twisting motion.
      9. Remove the old valve assembly by lifting it straight up and away from the mounting bracket.
      10. Position the new inlet valve (Miele part #10634820) into the mounting bracket, aligning the two screw holes.
      11. Install the two T20 Torx screws and tighten until snug (approximately 15-18 inch-pounds).
      12. Push the internal hose onto the valve outlet nipple until it bottoms out (approximately 1 inch deep).
      13. Slide the spring clamp forward to its original position 1/4 inch from the end of the hose.
      14. Reconnect the electrical connector until you hear a distinct click.
      15. Thread the water supply line onto the valve inlet, hand-tightening, then use the wrench to turn an additional 3/4 turn clockwise.
      16. Turn the water supply on and inspect all connections for leaks during a 2-minute observation period.
