Alan L Austin , TX August 17, 2026 Dishwasher (bosch) kept throwing an error code d30 or something like that your site told me to replace the water inlet valve I ordered the inlet valve and the door seals while i was on site... the repair worked. it took me longer to get the dishwasher out from under the counter than it did to change the valve and test it.. no problems since the repair. thanks Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
