8581190009028 Genuine Lid Reed Switch for Simpson, Westinghouse Top Load Washing Machines SWT6055TMWA SWT7055LMWA WWT6055TMWA SWT8043

Genuine reed sensor 8581190009028 is the lid switch for Simpson and Westinghouse top load washing machines. On the Simpson side it's listed for the SWT8043, SWT8063E, SWT6055TMWA and SWT7055LMWA, and the Westinghouse WWT6055TMWA and WWT7055LMWA use it too. In the shorter numbering it's 119000902, and 119000904 is also linked to it. Its job is to tell the washer the lid is closed before the machine will spin.

Signs of a faulty lid switch on a Simpson top loader

A reed switch is closed by a magnet rather than by direct contact. When the lid shuts, a magnet in the lid comes close to the sensor and the board knows it's safe to spin. If the sensor fails, the machine behaves as if the lid is always open. It may fill and wash but stop before spinning, beep or flash an error, or refuse to start a cycle at all. A cracked wire, or a magnet that has dropped out of the lid, can cause the same faults.

Fitting the lid switch

Unplug the washer first. The sensor usually sits under the top deck near the lid, so you'll need to lift or remove the top panel to reach it. Follow the wiring back to its plug, swap the sensor and route the new lead the same way, clear of sharp edges. Close the lid and run a quick spin to make sure it's detected.

Questions about this part

The washer stops before spin. Could it be the lid switch?

Yes, that's one of the most common signs. Also check the magnet in the lid is still in place and that nothing stops the lid closing fully before you replace the switch.
