Symptoms
• Dishwasher stops mid-cycle or fails to start the wash phase
• No water or insufficient water visible in the tub during operation
• Error code E03 displays on the control panel
• Water fill valve makes clicking sounds but water does not enter
• Cycle does not progress beyond the initial fill stage
• Damp interior but noticeably low water level compared to normal operation
Possible Causes
• Kinked, pinched, or clogged inlet hose connection to the dishwasher
• Closed or partially closed water supply valve under the sink
• Low household water pressure below the 20 psi minimum required by Bosch USA models
• Debris, mineral buildup, or sediment blocking the inlet screen or water inlet valve
• Faulty water inlet solenoid valve unable to open with standard 120V USA electrical supply
• Frozen water line or ice blockage (in cold climates or garages)
• Door not closing completely, triggering a safety interlock that prevents fill
• Defective door latch assembly preventing proper cycle initiation
Safety Checks You Can Do
• Turn off the dishwasher and locate the water supply shut-off valve under the sink, then check that it is fully open (turn counterclockwise)
• Inspect the inlet hose for visible kinks, cracks, or pinches and straighten any bent sections
• Disconnect the inlet hose from the water supply connection and run water into a bucket to confirm adequate household water pressure (should flow steadily; weak trickle suggests low pressure)
• Check that the home circuit breaker for the dishwasher has not tripped; reset if necessary
• Open and close the dishwasher door firmly several times to ensure it latches completely with an audible click
• Remove and inspect the inlet hose screen filter (usually found where the hose connects to the water supply) for debris or mineral deposits; rinse under running water if clogged
• Run a test cycle with the door closed and listen for a clicking sound from the inlet valve; silence may indicate a solenoid issue
• Verify no detergent dispenser flap or door obstruction is preventing the cycle from starting properly
• In cold climates, check that the water line to the dishwasher is not frozen by inspecting the supply area under the sink
Safety First
Always disconnect the appliance from power before performing any checks. If you are unsure about any step, please contact a qualified technician.
