DISPATCHAlways disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Frequently Asked Questions: Bompani A11
FAQ TREEWhat does error code A11 mean on a Bompani appliance?
Bompani error code A11 indicates: Bompani AquaStop Fully Integrated & Freestanding Eco-Wash Dishwasher: Operational diagnostic fault code A11 signaled by internal electronics. Water softening resin regeneration solenoid valve coil open circuit or disconnected.
What is the root cause of Bompani error code A11?
The primary root cause for Bompani code A11 is: On Bompani kitchen suites engineered with synchronous wash pump with run capacitor, 1800W flow-through heater (26-28 Ω), pneumatic pressure switch, optical turbidity sensor, and AquaStop tray switch: Solenoid copper wire broken at terminal pin, corrosion from brine leakage, or driver triac open Multimeter diagnostic parameter: regeneration valve solenoid coil resistance nominal 3.5 kΩ to 4.2 kΩ at 20°C; 230V AC drive voltage..
How do I fix or resolve Bompani error code A11?
To resolve error code A11: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: disconnect wiring plug from regeneration valve at side salt reservoir and measure coil resistance. Inspect spade lugs for signs of heat discoloration. Replace defective component, restore electrical supply, and perform system reset: Switch appliance off. Press and hold Start/Reset button for 4 seconds while powering on, release when LED flashes rapidly, clearing saved cycle errors.
Is it safe to clear Bompani error code A11 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bompani code A11 persists, the physical component causing On Bompani kitchen suites engineered with synchronous wash pump with run capacitor, 1800W flow-through heater (26-28 Ω), pneumatic pressure switch, optical turbidity sensor, and AquaStop tray switch: Solenoid copper wire broken at terminal pin, corrosion from brine leakage, or driver triac open Multimeter diagnostic parameter: regeneration valve solenoid coil resistance nominal 3.5 kΩ to 4.2 kΩ at 20°C; 230V AC drive voltage. must be inspected or replaced.
How do I test electrical resistance for Bompani code A11 using a multimeter?
Set a digital multimeter to ohms (Ω). Disconnect power and test Mechanical Pressure Switch Contacts / Inductive Frequency Sensor across Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal. Expected nominal reading is Mechanical: Continuity 0.0Ω–0.2Ω (Empty: 11-12, Full: 11-14). Electronic: 20Ω–45Ω coil resistance.. Tolerance: Mechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%..
What safety protocol must be followed before servicing Bompani code A11?
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.
