4055663357 Genuine Lid Lock Assembly 1550mm for Simpson, Westinghouse Top Load Washing Machines SWT9542 SWT1042A SWT8542 SWT9043 WWT1020A WWT854

If your Simpson or Westinghouse top loader won't start or spin, the lid lock is a common culprit. This genuine assembly, part 4055663357, is the 1550mm version and also goes by 119414520. It is listed for the SWT801, SWT8542, SWT9043, SWT9542 and SWT1042A, and for the WWT854, WWT8011 and WWT1020A top loaders, plus a few more models on the compatibility list.

Signs the lid lock on your top loader has failed

The lid lock tells the control board when the lid is closed and holds it shut while the bowl spins at speed. If the switch inside fails, or the latch no longer engages, the washer may refuse to start, stop part way through a cycle, skip the spin, or beep and show a lid error. Some faults work the other way around, with a lid that stays locked after the cycle has finished. Cracked housings, worn latches and damaged wiring at the plug are the usual causes, and a lid that has been slammed or forced open often speeds up the wear.

Replacing the lid lock

Unplug the washer before you open anything up. The lock is usually mounted under the top deck, so you'll need to lift or release the deck to reach it. Photograph the wiring and the route of the lead, then fit the new lock the same way, keeping the lead clear of moving parts. Run a short spin cycle to confirm the lid locks and releases.
