Seeing standing water, dirty dishes, or error codes from your Bosch dishwasher can be frustrating. Whether it won’t start, fill, drain, or dry, this guide walks you through practical fixes and when to call for help.
1. Dishwasher Won’t Start
If your Bosch dishwasher has no power or won’t begin a cycle:
- Door Closure: Ensure the door is fully latched—an unlatched door prevents the machine from starting. :contentReference[oaicite:1]{index=1}
- Child Lock: If control lock or child lock is active, buttons won’t respond. Check your manual to disable it. :contentReference[oaicite:2]{index=2}
- Power Reset: Turn off power at the breaker or unplug for 5+ seconds, then restart. This often clears minor electronic glitches. :contentReference[oaicite:3]{index=3}
2. Dishes Aren’t Getting Clean
Dirty or spotty dishes often point to filter, spray arm, or loading issues:
- Clean the Filter: Regularly clear debris from the filter basket to maintain water flow. :contentReference[oaicite:4]{index=4}
- Unblock Spray Arms: Confirm spray arms rotate freely and holes aren’t clogged. :contentReference[oaicite:5]{index=5}
- Use Proper Detergent: Bosch recommends high-quality dishwasher detergent. Avoid cheap or expired brands. :contentReference[oaicite:6]{index=6}
- Ideal Water Temperature: Cycle water should reach at least 120°F–150°F to dissolve food and detergent effectively. :contentReference[oaicite:7]{index=7}
3. Dishwasher Not Draining
Standing water after the cycle usually means a drainage issue:
- Clean Drain Filter and Pump: Remove the bottom rack, clean the filter, and check for debris near the pump impeller. :contentReference[oaicite:8]{index=8}
- Inspect the Drain Hose: Look for kinks or blockages. Detach and flush if needed. :contentReference[oaicite:9]{index=9}
- Check the Check Valve: A faulty check valve may allow dirty water back into the tub. Test it by pouring water through drain hose—if it returns, the valve is likely stuck. :contentReference[oaicite:10]{index=10}
- Weak or Faulty Pump: If filters and hoses are clean and it still won’t drain, the drain pump may be failing. :contentReference[oaicite:11]{index=11}
4. Dishwasher Fills or Keeps Filling with Water
Overfilling or random fills often indicate a water inlet valve issue:
- Faulty Water Inlet Valve: This valve opens for water and may stay open if faulty, causing the unit to overfill. Replacement is usually needed. :contentReference[oaicite:12]{index=12}
- Float Switch or Door Switch: A stuck float or malfunctioning door switch may misreport the water level. :contentReference[oaicite:13]{index=13}
5. Dishwasher Stops Mid‑Cycle
If your Bosch dishwasher quits before finishing a cycle:
- Door or Power Interruptions: Ensure no power outages, secure water supply, and that the door remains latched. :contentReference[oaicite:14]{index=14}
- Venting Issues: Steam pressure from a clogged vent may force the door open and abort the cycle. Ensure vent pathways are clear. :contentReference[oaicite:15]{index=15}
- Control Board or Faulty Pump: Persistent mid‑cycle failures may need professional diagnostics—especially concerning electronics or pumps. :contentReference[oaicite:16]{index=16}
6. Dishes Aren’t Drying Well
Wet dishes at the end usually mean missing rinse aid or drying options:
- Use Rinse Aid: It helps water sheet off dishes instead of clinging. Make sure the dispenser is full. :contentReference[oaicite:17]{index=17}
- Enable Extra Dry Mode: Select “Extra Dry” or high‑temp drying if your model supports it. :contentReference[oaicite:18]{index=18}
- Open Door Post‑Cycle: Crack open the door slightly to let steam escape and finish drying naturally. :contentReference[oaicite:19]{index=19}
7. Musty or Foul Odors
Bad smells in your Bosch dishwasher often come from trapped food and residue:
- Clean Food Debris Regularly: Scrape plates before loading and rinse filters every few months. :contentReference[oaicite:20]{index=20}
- Run a Cleaning Cycle: Every month, use a descaler or vinegar/baking soda cycle to remove build‑up and freshen the interior. :contentReference[oaicite:21]{index=21}
8. Error Codes or Display Problems
Bosch uses error codes like E14, E15, E24 to flag issues:
- Reset Errors: Hold Start/Cancel or reset power to clear alarms. If codes reappear, further diagnostics are needed. :contentReference[oaicite:22]{index=22}
- Error Guide: Use Bosch’s online support portal to lookup codes by model number. :contentReference[oaicite:23]{index=23}

Manage Dishwasher Age Wisely
Most dishwashers last around 10–15 years if maintained properly. Bosch units are durable—but if repair costs approach 50% of a new unit’s price and the machine is over 10 years old, consider replacing. Regular cleaning can extend lifespan significantly. :contentReference[oaicite:24]{index=24}
