It's also listed as 425221P. Models on file cover the GW500 to GW712 series, the IW509 to IW812 machines and MW models from the MW051 to the MW512, including the GW600, GW711, IW711 and IW810.\u003c\/p\u003e\n\u003ch2\u003eFisher \u0026amp; Paykel SmartDrive won't spin or agitate\u003c\/h2\u003e\n\u003cp\u003eA SmartDrive washer has no brushes or gearbox in its motor. The rotor position sensor reads where the rotor magnets are as they pass, so the motor controller knows which windings to power and when. When the sensor fails, the motor can't be driven properly. The basket may jerk, shudder or vibrate instead of turning, you might hear clicking at the start of agitate or spin, or a motor fault may show. Moisture on the board is a common cause.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGenuine Fisher \u0026amp; Paykel part 420296P\u003c\/li\u003e\n\u003cli\u003eMk2 service version\u003c\/li\u003e\n\u003cli\u003eAlso listed as 425221P\u003c\/li\u003e\n\u003cli\u003eSuits SmartDrive top loaders in the GW, IW and MW ranges\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\u003ctr\u003e\n\u003cth\u003eVersion\u003c\/th\u003e\n\u003ctd\u003eMk2 service part\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eChanging the rotor position sensor\u003c\/h2\u003e\n\u003cp\u003eUnplug the washer and turn off both taps. The sensor sits on the stator under the machine, so the rotor has to come off first. Tilt the machine back against a wall with a helper, undo the rotor nut and pull the rotor straight off. Unplug and unclip the old sensor, fit the new one in the same position, then refit the rotor and test on a short cycle.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eIs 425221P the same part?\u003c\/h3\u003e\u003cp\u003eYes, 425221P is cross referenced to 420296P, which is the Mk2 service version.
