What this guide covers
Symptoms: Won’t start
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 door latch firstBosch notes that an unlatched door prevents a cycle from starting.
- Check Child Lock / control lockA control lock can prevent normal start input.
- Check external powerBosch recommends confirming the power cord/outlet and home breaker if the dishwasher has no power.
- Try a short power cycleBosch suggests disconnecting power briefly and then retrying when the dishwasher has power but will not start.

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.
