Symptom / Description

FAULT

Ariston Hotpoint-Ariston Aqualtis Heat Pump Tumble Dryer: Heating element open circuit or heat pump compressor failure F08; air chamber temperature fails to rise by 5°C in 15 minutes.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Ariston tumble dryers: Broken nichrome coil on dual heating element (28 Ω + 36 Ω), tripped manual high-limit stat, or seized heat-pump compressor.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Check red reset button on rear heater casing. Measure resistance of both heating circuits (approx 28 Ω and 36 Ω). In heat pump units, verify compressor windings. Hold Start/Pause key for 5 seconds until indicator extinguishes, rotate program dial to 0, and clean lint trap.

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.

Frequently Asked Questions: Ariston F08

FAQ TREE

What does error code F08 mean on a Ariston appliance?

Ariston error code F08 indicates: Ariston Hotpoint-Ariston Aqualtis Heat Pump Tumble Dryer: Heating element open circuit or heat pump compressor failure F08; air chamber temperature fails to rise by 5°C in 15 minutes..

What is the root cause of Ariston error code F08?

The primary root cause for Ariston code F08 is: On Ariston tumble dryers: Broken nichrome coil on dual heating element (28 Ω + 36 Ω), tripped manual high-limit stat, or seized heat-pump compressor..

How do I fix or resolve Ariston error code F08?

To resolve error code F08: Check red reset button on rear heater casing. Measure resistance of both heating circuits (approx 28 Ω and 36 Ω). In heat pump units, verify compressor windings. Hold Start/Pause key for 5 seconds until indicator extinguishes, rotate program dial to 0, and clean lint trap.

Is it safe to clear Ariston error code F08 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Ariston code F08 persists, the physical component causing On Ariston tumble dryers: Broken nichrome coil on dual heating element (28 Ω + 36 Ω), tripped manual high-limit stat, or seized heat-pump compressor. must be inspected or replaced.

How do I test electrical resistance for Ariston code F08 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..

What safety protocol must be followed before servicing Ariston code F08?

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.
