Bosch Dishwasher: not functioning as expected
What is this symptom?
Is your Bosch dishwasher not functioning as expected? It may not start, stop mid-cycle, or fail to fill or drain properly. Common issues include a faulty door latch, power supply problems, or water supply issues. Understanding these symptoms can help you identify and resolve the problem quickly.
Important Tips for Bosch Models
- Bosch dishwashers may show specific error codes (e.g., E24 for drain issues, E15 for water in base) that can guide diagnosis
Possible Causes
Door latch or door not fully closed
How to Identify: Dishwasher will not start or starts then stops; red light flashing or control indicates door issue; door doesn’t click firmly closed.
Part: Door latch assembly / door switch
Power supply issue (breaker, fuse, outlet)
How to Identify: Dishwasher shows no lights, doesn’t start at all; breaker tripped; outlet not supplying power.
Part: Circuit breaker / power connection / internal fuse
Water supply problem
How to Identify: Dishwasher won’t fill with water; cycle won’t start or stops early; possibly error codes for water fill issues.
Part: Water inlet valve / supply line / float switch
