Castor AL6

Q: Is it safe to clear Castor error code AL6 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Castor code AL6 persists, the physical component causing On Castor (Castor CDF Series / Lavastoviglie Silenziosa Dishwasher) models: Open heating element (nominal 25–28 Ω), tripped Klixon safety thermostat on heater casing, or open heating relay contact on PCB. must be inspected or replaced.

Q: How do I test electrical resistance for Castor code AL6 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Immersion / Air Heating Element & Klixon Thermostat across Between element terminals (unwired). Insulation to earth casing: >20MΩ (OL). Expected nominal reading is 25Ω–28Ω (230V / 2000W) / <0.5Ω (Safety Klixon closed). Tolerance: Formula R = V²/P (±5%). Any earth leakage reading below 2MΩ will trip the domestic 30mA RCD breaker..

Q: What safety protocol must be followed before servicing Castor code AL6?

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.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Cut electrical mains power. Never measure resistance on energized heating circuits.
!Ensure tub water or heating cavity is completely drained and cool to the touch before dismantling.
!Verify absolute zero voltage using an approved 2-pole voltage detector before touching element terminals.

3. Preliminary Mechanical & Visual Checks

Inspect heating element tube for calcification buildup, bulging, pinholes, or blistering.
Check wiring spade terminals for heat discoloration, burnt insulation, or loose crimps.
On thermal Klixon switches: check for manual red reset buttons and verify spring-loaded snap action.
