1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Isolate 230V mains power before accessing the lower pump housing.
!Prepare a shallow basin and absorption towels: expect 3 to 10 liters of stagnant trapped water upon filter opening.
!Beware of sharp foreign objects (broken glass, needles, screws) trapped inside the impeller cavity.

3. Preliminary Mechanical & Visual Checks

Unscrew coin trap filter and clear all foreign debris (coins, hairpins, bra underwires).
Rotate pump impeller manually: synchronous magnetic rotors should snap cleanly in 90° intervals without jamming.
Check drain hose for kinks, blockages, or unpunched sink spigots; verify drain height is between 65cm and 100cm.

Frequently Asked Questions: Atlantic I20

FAQ TREE

What does error code I20 mean on a Atlantic appliance?

Atlantic error code I20 indicates: Water left in the bottom of dishwasher after cycle.

What is the root cause of Atlantic error code I20?

The primary root cause for Atlantic code I20 is: Drain filter or drain hose is blocked..

How do I fix or resolve Atlantic error code I20?

To resolve error code I20: Remove and clean the filters in the bottom of the dishwasher. Check the drain hose for kinks or blockages.

Is it safe to clear Atlantic error code I20 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Atlantic code I20 persists, the physical component causing Drain filter or drain hose is blocked. must be inspected or replaced.

How do I test electrical resistance for Atlantic code I20 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

What safety protocol must be followed before servicing Atlantic code I20?

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.
