Bosch E5116

Q: How do I fix or resolve Bosch error code E5116?

To resolve error code E5116: DANGER: Disconnect mains and discharge high-voltage capacitor. Measure magnetron filament resistance across terminals ( 1 Ω). Turn function selector to 0, isolate power at circuit breaker for 60 seconds, restore power and set the digital clock.

Q: How do I test electrical resistance for Bosch code E5116 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Immersion / Air Heating Element & Klixon Thermostat across Between element terminals (unwired). Insulation to earth casing: >20MΩ (OL). Expected nominal reading is 25Ω–28Ω (230V / 2000W) / <0.5Ω (Safety Klixon closed). Tolerance: Formula R = V²/P (±5%). Any earth leakage reading below 2MΩ will trip the domestic 30mA RCD breaker..

Q: What safety protocol must be followed before servicing Bosch code E5116?

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.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Cut electrical mains power. Never measure resistance on energized heating circuits.
!Ensure tub water or heating cavity is completely drained and cool to the touch before dismantling.
!Verify absolute zero voltage using an approved 2-pole voltage detector before touching element terminals.

3. Preliminary Mechanical & Visual Checks

Inspect heating element tube for calcification buildup, bulging, pinholes, or blistering.
Check wiring spade terminals for heat discoloration, burnt insulation, or loose crimps.
On thermal Klixon switches: check for manual red reset buttons and verify spring-loaded snap action.

Frequently Asked Questions: Bosch E5116

FAQ TREE

What does error code E5116 mean on a Bosch appliance?

Bosch error code E5116 indicates: Bosch Serie 6 / Serie 8 4D Hotair & EcoClean Direct Pyrolytic Oven: Combi-microwave inverter magnetron heater open circuit E5116; magnetron filament open or high-voltage inverter output missing..

What is the root cause of Bosch error code E5116?

The primary root cause for Bosch code E5116 is: On Bosch ovens: Burned-out filament in 2M261 magnetron tube (nominal < 0.2 Ω), blown high-voltage fuse, or defective resonant inverter board..

How do I fix or resolve Bosch error code E5116?

To resolve error code E5116: DANGER: Disconnect mains and discharge high-voltage capacitor. Measure magnetron filament resistance across terminals (< 0.2 Ω; open if > 1 Ω). Turn function selector to 0, isolate power at circuit breaker for 60 seconds, restore power and set the digital clock.

Is it safe to clear Bosch error code E5116 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bosch code E5116 persists, the physical component causing On Bosch ovens: Burned-out filament in 2M261 magnetron tube (nominal < 0.2 Ω), blown high-voltage fuse, or defective resonant inverter board. must be inspected or replaced.
