      🔧 Step 1: Remove water inlet valve

      1. Turn off the water supply valve located under your sink or at the wall behind the dishwasher – rotate the valve handle clockwise until it stops.
      2. Switch off the circuit breaker dedicated to the dishwasher at your electrical panel.
      3. Pull the dishwasher forward approximately 12 inches from under the counter to access the bottom panel.
      4. Locate the lower access panel on the front bottom of the dishwasher, spanning the full width and approximately 4 inches tall.
      5. Remove the two T15 Torx screws securing this lower access panel – one screw positioned at each bottom corner, approximately 2 inches from each side edge.
      6. Pull the access panel straight down and away to expose the internal components.
      7. Identify the water inlet valve – a brass-colored component mounted on the left side of the base, approximately 3 inches from the left edge and 2 inches back from the front edge.
      8. Place a shallow pan or towels beneath the inlet valve to catch residual water (expect 1-2 cups).
      9. Use slip-joint pliers to loosen the compression fitting connecting the water supply line to the inlet valve – rotate counterclockwise 3-4 full turns until the fitting releases.
      10. Disconnect the water supply line completely and allow water to drain into your pan.
      11. Locate the wire harness connector attached to the inlet valve – a white rectangular connector with two wires (typically white and black).
      12. Press the locking tab on top of the connector while pulling the connector straight away from the valve terminals.
      13. Use a 5/16-inch nut driver to remove the two mounting screws securing the valve bracket to the dishwasher base – screws are located at the top and bottom of the mounting bracket.
      14. Lift the inlet valve assembly straight up and out from the mounting bracket.

      🛠️ Step 2: Clean valve screen thoroughly

      1. Hold the inlet valve assembly you removed in Step 1 with the threaded inlet port facing you.
      2. Look inside the threaded brass fitting where the water supply line connects—you’ll see a small cylindrical metal mesh screen (approximately 1/4 inch diameter) seated inside the valve inlet.
      3. Use needle-nose pliers to grip the outer edge of the screen filter and pull straight out with firm, steady pressure until it releases from the valve body.
      4. Fill a small bowl with 1 cup of white vinegar and submerge the screen completely for 10 minutes to dissolve mineral deposits and calcium buildup.
      5. Remove the screen from the vinegar and hold it under running tap water at full pressure for 30 seconds.
      6. Examine the screen mesh under good lighting—the individual openings should be completely clear with no white, brown, or green deposits visible.
      7. If debris remains visible, use a soft-bristled toothbrush to scrub both sides of the screen in circular motions for 1 minute while holding it under running water.
      8. For stubborn deposits, soak the screen in vinegar for an additional 20 minutes, then repeat the brushing process.
      9. Inspect the rubber gasket or O-ring seated in the groove around the screen opening inside the valve body—it should be black, pliable, and free of cracks.
      10. If the O-ring appears flattened, cracked, or brittle, pry it out using a small flathead screwdriver and replace it with a new 3/4-inch rubber O-ring.
      11. Press the cleaned screen back into the valve inlet opening, flat side facing outward, until it sits flush and level with the threaded brass fitting edge.
      12. The screen is properly seated when you cannot see any gap between the screen edge and the valve body, and it does not move when touched with your finger.

      ⚙️ Step 3: Test valve solenoids with multimeter

      1. Set your digital multimeter to the Ohms (Ω) setting at 200 ohms range by rotating the dial to the omega symbol.
      2. Locate the water inlet valve assembly at the bottom left corner of the dishwasher, approximately 3 inches from the left side panel and 2 inches behind the front edge.
      3. Identify the two solenoid coils mounted on the inlet valve – one positioned on the left side and one on the right side of the valve body, each with two metal terminals protruding from the top.
      4. Touch one multimeter probe to the first terminal on the left solenoid and the other probe to the second terminal on the same solenoid.
      5. Read the resistance value on the multimeter display – you should see a reading between 500 and 1,500 ohms, which indicates a functioning solenoid coil.
      6. Record this reading, then move to the right solenoid and repeat the test by placing one probe on each of its two terminals.
      7. Verify the right solenoid also displays between 500 and 1,500 ohms on the multimeter.
      8. If either solenoid reads “OL” (open loop/infinite resistance) or “0” (zero resistance/short circuit), the valve assembly has failed and requires replacement with Bosch part number 00611316.
      9. Switch your multimeter to continuity mode (symbol showing sound waves or diode) by rotating the dial one position.
      10. Touch one probe to either solenoid terminal and the other probe to the metal valve body – the multimeter should NOT beep or show continuity, confirming proper insulation.
      11. If the multimeter beeps during this test, the solenoid coil has internal damage allowing electricity to ground through the valve body, requiring valve replacement.
      12. Disconnect the multimeter probes from the valve terminals and turn off the multimeter.

      🔩 Step 4: Inspect valve for sediment

      1. Locate the water inlet valve at the bottom left corner of the dishwasher, approximately 3 inches from the left edge and 2 inches back from the front panel.
      2. Position your flashlight to illuminate the valve body and the brass screen filter visible inside the threaded inlet port where the water supply line connects.
      3. Use needle-nose pliers to grip the edge of the circular mesh screen filter inside the inlet port.
      4. Pull the screen filter straight out from the valve body with steady pressure – it will release after approximately 1/4 inch of movement.
      5. Hold the screen filter under bright light and examine both sides for white, brown, or greenish mineral deposits, sand particles, or rust flakes trapped in the mesh.
      6. Run your finger across the mesh – clean screens feel smooth, while sediment-blocked screens feel rough or gritty.
      7. Place the screen filter in a small bowl containing equal parts white vinegar and warm water if you see any mineral buildup.
      8. Let the filter soak for 15 minutes while sediment dissolves.
      9. Remove the filter from the vinegar solution and rinse under running tap water for 30 seconds.
      10. Use a soft-bristle toothbrush to scrub both sides of the screen in circular motions for 20-30 strokes.
      11. Hold the clean screen up to light – you should see light passing through all mesh openings uniformly.
      12. Insert a straightened paper clip or thin wire through 5-10 random mesh holes to verify they’re completely clear.
      13. Inspect the valve inlet port opening using your flashlight – look for sediment deposits on the brass threading or plastic housing around the port.
      14. Wrap a damp cloth around your index finger and wipe the inside of the inlet port, rotating your finger 360 degrees to collect any remaining debris.
      15. Set the cleaned screen filter aside on a clean towel for reinstallation in Step 5.

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

      1. Order Bosch replacement water inlet valve part number 00658936 or compatible equivalent – verify by matching the electrical connector configuration (2-pin solenoid connectors) and the 3/4-inch NPT threaded inlet.
      2. Turn off the water supply valve under the sink by rotating clockwise until fully closed.
      3. Pull the dishwasher forward 12-18 inches from the cabinet to access the right side panel where the inlet valve is located.
      4. Use a 1/4-inch nut driver to remove the two screws securing the right-side lower access panel (located 3 inches from the front edge and 2 inches from the bottom).
      5. Locate the water inlet valve – a brass and plastic assembly mounted vertically on the right side, 8 inches from the front and 4 inches from the bottom.
      6. Place a shallow pan underneath the valve to catch residual water (expect 1-2 cups).
      7. Use an adjustable wrench to loosen the 3/4-inch compression nut connecting the water supply line to the inlet valve by rotating counterclockwise 4-5 full turns until free.
      8. Disconnect both electrical connectors from the dual solenoids by pressing the locking tab on each connector and pulling straight out – they require approximately 3-4 pounds of pull force.
      9. Disconnect the internal hose from the outlet port by squeezing the spring clamp with slip-joint pliers and sliding it back 1 inch, then twisting and pulling the hose off.
      10. Remove the single mounting screw securing the valve bracket using a T20 Torx bit.
      11. Lift the old valve straight up and out of the mounting bracket.
      12. Insert the new valve into the bracket with the solenoids facing outward and reinstall the T20 Torx mounting screw, tightening until snug (approximately 15-18 inch-pounds).
      13. Reattach the internal hose to the outlet port, sliding it on 3/4 inch, then repositioning the spring clamp 1/4 inch from the end.
      14. Reconnect both solenoid electrical connectors – they will click when fully seated.
      15. Thread the water supply line compression nut onto the inlet by hand, then tighten with the adjustable wrench one full turn past hand-tight.
      16. Turn on the water supply valve and check for leaks at all connections.
