Bosch Dishwasher E16 Error Code
Water not entering the tub correctly
What this error means
E16 (often paired with E17 on some firmware) means water is not entering the dishwasher correctly—the fill system timed out or the level stayed too low after the inlet valve opened. Distinct from E14 which specifically flags the flow meter.
How E16 is detected
E16 on Bosch dishwasher units indicates the drive system did not meet expected performance. Direct-drive washers monitor rotor position with a hall sensor; dryers and dishwashers track motor current draw. When the drum or spray arm fails to turn, the inverter or motor relay shuts down to prevent burned windings. Bosch SHPM65Z55N, Bosch SHE53B75UC, and similar variants may show this fault after an overloaded tub or a foreign object jam.
Kinked or damaged inlet hose under the sink is a leading trigger. Start with inspect the full inlet hose path from valve to dishwasher for kinks. Rotate the drum or spray arm by hand when powered off—it should move without grinding. Grinding confirms mechanical obstruction; free rotation with repeated E16 on light loads suggests hall sensor, motor, or inverter board failure requiring professional diagnosis.
Common causes
- Kinked or damaged inlet hose under the sink
- Supply valve closed or flow restrictor installed upstream
- Inlet valve screen clogged with sediment
- Fill phase aborted by air gap siphon effect on improper install
Step-by-step fixes
- 1Inspect the full inlet hose path from valve to dishwasher for kinks
- 2Open the supply valve fully and remove any aftermarket flow restrictors
- 3Disconnect the hose and confirm roughly 10 liters per minute flow into a bucket
- 4Reset breaker thirty seconds after verifying supply
When to call a technician
Confirmed strong inlet flow with recurring E16 requires inlet valve or fill pressure switch service.
Affected models
- Bosch SHPM65Z55N
- Bosch SHE53B75UC
- Bosch SHX878ZD5N
Prevention & maintenance
- Avoid washing single heavy rugs or shoes that bind the drum; distribute weight evenly to reduce motor strain that precedes E16.
- Record when E16 appears in the cycle and whether it clears after a 60-second power reset on your Bosch dishwasher—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for E16; Bosch uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting E16; reversed plugs on pumps and valves cause immediate repeat faults.
