Field Actions
DISPATCHAlways disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Frequently Asked Questions: Bosch E16
FAQ TREEWhat does error code E16 mean on a Bosch appliance?
Bosch error code E16 indicates: Water loading (impulses from flow meter) without solenoid valve control or appliance recognizes impulses from tachometric generator although no water is loaded (cycle interrupted with drain).
What is the root cause of Bosch error code E16?
The primary root cause for Bosch code E16 is: Defective PCB Power Supply Rails & DC Bus Filter Capacitors, open/short circuit in the wiring harness, or faulty connector on the electronic control board (pcb) & bus communications..
How do I fix or resolve Bosch error code E16?
To resolve error code E16: Check the loading valve and its control. Check the loading solenoid valve.
Is it safe to clear Bosch error code E16 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bosch code E16 persists, the physical component causing Defective PCB Power Supply Rails & DC Bus Filter Capacitors, open/short circuit in the wiring harness, or faulty connector on the electronic control board (pcb) & bus communications. must be inspected or replaced.
How do I test electrical resistance for Bosch code E16 using a multimeter?
Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..
What safety protocol must be followed before servicing Bosch code E16?
Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
