Noisy washing machine? Signs of a worn lower bearing

The lower bearing supports the shaft that drives the wash action, keeping it centred as it turns. As it wears, you'll hear rumbling, grinding or a high pitched whine, especially on spin. Other signs include play or wobble in the shaft, rusty streaks below the machine and water leaking from the base, as failed bearings often go hand in hand with a worn seal. Left too long, a dry bearing can damage the shaft and gearbox, turning a moderate repair into a costly one.

Fitting the lower bearing

Bearing replacement is an advanced repair that usually means stripping the machine down to the transmission or tub, so many owners leave it to an appliance technician. Unplug the washer and turn off both taps first. Replace the matching seal at the same time, press the bearing in squarely using the right tools rather than a hammer, and check the shaft turns freely before reassembly.

Questions about this part

How do I find my Simpson or Westinghouse model number?

Look for the label on the back of the machine or under the lid. Older models show a code like 22S800L or 36A402P followed by a series number. Match it to the fit list or send it through the parts enquiry form.
