Bompani A07

Bompani error code A07 indicates: Bompani AquaStop Fully Integrated & Freestanding Eco-Wash Dishwasher: Operational diagnostic fault code A07 signaled by internal electronics. Water level pressure switch contact stuck in full or empty position, or air dome tube blocked.

The primary root cause for Bompani code A07 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: Grease and detergent scum clogging the pressure chamber, perforated rubber tube, or microswitch welded Multimeter diagnostic parameter: pressure switch contact continuity <0.1 Ω in switched state; pneumatic hose airtight at 50 mbar test..

To resolve error code A07: Safely de-energize the appliance at the electrical distribution board. Unplug wiring connector from the affected component and verify with a digital multimeter: blow gently into pressure switch while testing contact continuity across common and normally open terminals. 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 A07 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: Grease and detergent scum clogging the pressure chamber, perforated rubber tube, or microswitch welded Multimeter diagnostic parameter: pressure switch contact continuity <0.1 Ω in switched state; pneumatic hose airtight at 50 mbar test. 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.
