Bosch dishwasher not filling with water
Bosch identifies water-supply, inlet-hose, inlet-valve, float, and door-switch issues as possible causes; owner checks should stop at the external supply and hose.
What this guide covers
Symptoms: Won’t fill / no water entering
This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.

Safe troubleshooting sequence
Start with the observations and external checks that can be verified without opening energized assemblies. The interactive version asks these in order and changes the path based on your answers.
- Check the water supplyA dishwasher cannot fill if the household water supply to the appliance is shut off.
- Inspect the visible inlet hoseBosch lists water-supply and inlet-hose issues among possible causes of a no-fill condition.
What the answers can lead to
Restore the dishwasher water supply
A closed household supply must be corrected before appliance components can be evaluated.
Evidence strength: Strong
Correct the inlet-hose restriction
A kinked or damaged inlet hose can prevent adequate water from reaching the dishwasher.
Evidence strength: Strong
The owner-level water-supply checks are exhausted
If the supply is open and the inlet hose is unobstructed but the dishwasher still does not fill, Bosch lists internal inlet, float, or door-switch causes that need proper assessment.
Evidence strength: Moderate
When professional diagnosis is the safer next step
If the supply is open and the inlet hose is unobstructed but the dishwasher still does not fill, Bosch lists internal inlet, float, or door-switch causes that need proper assessment.
Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.
Repair or replace?
A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict’s interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
