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 18
o
C.
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.
