E.3 INTRODUCTION to IW

This Service Supplement contains specifications, size setting and diagnostic mode.

The first Intuitive Washer(IW) was introduced in Phase 5 Smartdrive in 1999. Three models were released, IW509, IW609 and IW709. These products were upgraded in 2000 to include recirculation, these products are called Intuitive ECO. These products were IWC09 (non recirc), IWM10, IW710, IWL10 and IW810.

PERFORMANCE CHANGES

The Eco Active wash with Recirculation - Only IWM10 IW710 IWL10 IW810

The Eco Active wash of the Intuitive / Eco is a 2 step wash process that combines top loader and front loader washing technologies.

Wash 1: DETERGENT ACTIVATING WASH (Front loader type wash)

Smartdrive fills the bowl with just enough water, at the selected wash temperature, so that the clothes are 100% saturated. Smartdrive stops filling and the water in the bowl is pumped up through the recirculating hose and back into the bowl onto the clothes, with a fan-like spray pattern. As the water recirculates, the bowl stirs, pausing every 16 seconds. Short top-ups may occur as garments absorb water, keeping the water level constant. This recirculating wash action thoroughly dissolves and activates the detergent. The concentrated solution of detergent and water rapidly targets stains and soils at the fibre level, boosting soil removal and accelerating the wash process.

Wash 2: AGITATION WASH (Top loader type wash)

After re-circulating the sudsy water through the clothes for 2 to 5 minutes, Smartdrive fills with just enough cold water to suspend the clothes in solution. Smartdrive then senses the fabric type of the load and begins the agitation wash.

The are 2 load sensing methods to ensure the right wash action is used for the type and size of wash load;

LSD - Load Sensing Detection is used to continually sense the load and automatically adjust the agitation profiles to suit the wash load. If additional garments are added during the wash Smartdrive will adjust accordingly.

MCP – Maximum Capacity Profile is selected immediately when fabric detection selects ‘heavy duty’ at high water level.

ELECTRONICS

The electronics are similar to Smartdrive Phase 5. Electronic Modules are not inter-changeablebetween models. The different modules for the different models can be identified by their colour. Phase 2 modules are blue, Phase 3 modules are green, Phase 4 modules are yellow and the latest Phase 5 and IW modules are grey. IMPORTANT: Motor Controller part no. 426520 should not be used with IW. It will appear to function correctly but will give fault code 105 at the start of Agitate. Display Module 426961 should not be used on products with recirculation, the product will appear to work satisfactorily but the
