28. ng Detection is used to continually sense the load and automatically adjust the agitation profiles to suit the wash load It is also used to determine when a maximum capacity profile needs to be used If additional garments are added during the cycle the washer will adjust accordingly increasing the amount of water and changing the wash profile If the machine is operating on high water level regular cycle with a very large heavy load then the Load Sensing Detection will activate the Maximum Capacity Profile e MCP Maximum Capacity Profile is present in the regular cycle high water level only It is clearly noticeable The machine will stop agitating and restart with a perceivably different profile The agitation time will also increase by 1 minute MCP usually occurs 1 3 minutes into the wash and will of cause only occur if the machine is heavily loaded ELECTRONICS The electronics for Series 10 Smart Drive are now air cooled instead of being water cooled as in previous models This has been made possible by changes to the stator winding which allows a lower current through the electronics and the use of the latest low loss semiconductor switching device With the Series 10 Smart Drive you can no longer turn the machine on by using the cycle buttons you must press the Power button first The delay start is now 1 3 or 9 hours previous models were 1 6 or 9 hours This change was introduced as a result of the last customer survey On the

33. w uses a vortex impeller which reduces the operating sound levels at the end of the drain cycle The way we control the pump has changed During the drain cycle the pump is stopped and started quickly every 10 seconds When the pump stops the water keeps flowing flushing away any lint in the pump chamber The pump is now part of the electronic circuit and acts as a brake resistor as well as being part of the switch mode power supply We run the pump at 60Hz at the beginning of the drain cycle and change to 50Hz when the water level reaches the bowl check stage The pulsing on and off of the drain pump only occurs during the 60Hz stage If the mains voltage drops below approximately 106 VAC the 60Hz mode is disabled until the module is reset Because the pump is part of the switch mode power supply it is important to first check the pump before changing a module for no power If the pump s thermal overload goes open circuit the power to the module will be lost so no fault will be reported When the thermal device has reset the module will power up normally This could take between 3 10 minutes depending on the temperature of the pump at the time of failure The number of times the auto restart feature tries to start a stalled pump has been reduced to prevent nuisance tripping of the pump s thermal overload Note If the pump has blocked and the thermal overload has gone open circuit just remove the blockage from the pump the module
