Symptoms
• Dishwasher does not fill with water or fills very slowly
• Wash cycle stops or does not begin
• Error code E04 appears on the digital display
• No water sounds heard during normal fill phase
• Dishes remain dry or partially wet after cycle completion
• Control panel may beep or flash warning lights
Possible Causes
• Kinked or pinched inlet water hose
• Clogged water inlet valve due to mineral deposits or debris
• Low home water pressure below the 20 psi minimum requirement for USA models
• Closed or partially closed water shut-off valve under the sink
• Faulty water inlet valve solenoid (120V electrical component)
• Clogged inlet screen filter inside the dishwasher connection point
• Tripped home electrical circuit breaker affecting the 120V/60Hz water inlet valve
• Defective fill valve assembly
• Water supply line issue or main home water supply problem
Safety Checks You Can Do
• Check the home circuit breaker for the kitchen outlet to ensure power is fully restored; flip the breaker off and on again if tripped
• Locate the water shut-off valve under the sink and confirm it is fully open (turn counterclockwise)
• Inspect both inlet hoses running from the shut-off valve to the dishwasher for visible kinks, cracks, or pinches; straighten any bent sections
• Turn off the water shut-off valve, disconnect the inlet hose from the dishwasher, and run water into a bucket to verify adequate home water pressure and flow
• If water pressure is very low, check if other faucets in your home have reduced pressure, which may indicate a home water supply issue
• Reconnect the inlet hose securely to the dishwasher connection point
• Look for the inlet screen filter (small mesh screen at the connection point inside the dishwasher) and gently clean it with a soft brush if accessible without disassembly
• Run a test cycle and listen for water fill sounds to confirm the issue is resolved
• If water inlet appears normal but error persists, the internal water inlet valve may require professional service
