Bompani A19

Bompani error code A19 indicates: Bompani AquaStop Fully Integrated & Freestanding Eco-Wash Dishwasher: Operational diagnostic fault code A19 signaled by internal electronics. Lower or upper wash spray arm rotation sensor signal missing (<15 RPM rotation detected).

The primary root cause for Bompani code A19 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: Spray nozzles blocked with food residue or toothpicks, tall plate blocking arm rotation, or magnet missing Multimeter diagnostic parameter: Hall sensor generates pulses at 25-45 RPM under normal circulation pump pressure; 5V DC supply rail..

To resolve error code A19: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: clear wash nozzles with pin, spin spray arm by hand to check bearing clearance, and test Hall sensor pulses. 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.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bompani code A19 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: Spray nozzles blocked with food residue or toothpicks, tall plate blocking arm rotation, or magnet missing Multimeter diagnostic parameter: Hall sensor generates pulses at 25-45 RPM under normal circulation pump pressure; 5V DC supply rail. must be inspected or replaced.

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%..

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.
