Bompani A03

Bompani error code A03 indicates: Bompani AquaStop Fully Integrated & Freestanding Eco-Wash Dishwasher: Operational diagnostic fault code A03 signaled by internal electronics. Water drain timeout exceeded (sump water not evacuated below empty threshold within 4 minutes).

The primary root cause for Bompani code A03 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: Drain pump impeller jammed by toothpick or glass shard, drain hose kinked, or pump winding burned Multimeter diagnostic parameter: synchronous drain pump motor winding resistance nominal 160 Ω to 210 Ω at 20°C; rotor free rotation..

To resolve error code A03: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: measure resistance across drain pump terminals (expect 160-210 Ω) and inspect impeller chamber for obstructions. 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 A03 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: Drain pump impeller jammed by toothpick or glass shard, drain hose kinked, or pump winding burned Multimeter diagnostic parameter: synchronous drain pump motor winding resistance nominal 160 Ω to 210 Ω at 20°C; rotor free rotation. 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.
