recirculation will not work. It is important not to mix the different coloured modules as they are not compatible and Smartdrive will not work. It will normally display a fault code and beep if the modules have been mismatched. Delay start is 1 to 9 hours, (IW) or 18 hours (IWECO) in increments of 1 hour.

WATER TEMPERATURE SENSING

The thermistor for sensing the water temperature in Smartdrive is located in the inlet chamber and is available as a separate spare part, part number 479164P. Hot water is only used at the start of the cycle when Smartdrive is recirculating. Some hot water may be used in the first fill if the inlet water temperature is low, below 18oC.

WATER VALVES

The water valves are the same as Phase 5 GW Smartdrive. A proportional valve is fitted on the cold and a digital valve on the hot. Resistance 64 ohms.

STATOR & ROTOR

The stator & rotor are the same as Phase 5. Stator resistance is 16 ohms per winding, (32 ohms phase to phase).

RECIRCULATING VALVE - Only fitted to IWM10 IW710 IWL10 IW810

The Recirculating valve is situated at the bottom of the bowl beside the pump. If the valve requires service, remove the hose clips connecting the hoses to the valve, and remove the screwed clamp around the inlet hose to the valve. The valve now can remove for cleaning or checking. This is best achieved by working from underneath Smartdrive. The valve relies on element heating to open. The picture below shows the connector for the Recirculating valve in the motor controller module. The valve can be tested in the DIAGNOSTIC mode within the Machine Status screen. NB: The valve takes approx. 1 minute to activate and approx. 3 minutes to cool down and return to it normal position. It will make no sound during activation.
