Symptoms
• Dishwasher does not fill with water or fills very slowly
• Wash cycle starts but stops prematurely
• Display shows E02 error code and cycle halts
• Water pressure appears weak during fill phase
• Door lock engages but no water enters the tub
• Error clears temporarily but returns on next cycle
Possible Causes
• Water supply shutoff valve (under sink or at main) is partially or fully closed
• Inlet water line kinks, bends, or is crimped
• Clogged inlet water filter screen (common debris from municipal water lines)
• Water supply line frozen (in cold climates) or damaged
• Home water pressure below minimum threshold (Bosch USA models require 20-116 psi)
• Faulty water inlet valve solenoid not responding to electrical signal
• Kinked or pinched fill hose between wall connection and dishwasher
• Low home water pressure due to high demand or municipal supply issues
Safety Checks You Can Do
• Check the water supply shutoff valve under the sink and verify it is fully open (turn counterclockwise)
• Inspect the inlet water line for visible kinks, cracks, or damage along its entire length
• Verify your home's main water shutoff valve is open and water pressure is adequate at other faucets
• Check that the dishwasher inlet hose is not compressed behind or beneath cabinetry
• Locate and inspect the small inlet water filter screen inside the dishwasher connection point for debris or mineral buildup
• Run a short cycle and listen for the fill valve clicking sound (indicates electrical power reaching the valve)
• Ensure the dishwasher's power supply is stable by checking your home's circuit breaker panel for tripped breakers
• If water is available at other fixtures, try running hot water at the kitchen sink for 30 seconds to prime the line
• Check that you are using the correct inlet connection (hot or cold water line as specified for your model)
• Disconnect the inlet hose, place it in a bucket, and turn on the shutoff valve to verify strong water flow
Safety First
