146258 Genuine Drain Pump 00146258 for Bosch Front Load Washing Machines WAW28460AU WAW28420AU WAP24160AU WGA254U0AU, Replaces 00146193

When a Bosch front loader stops draining, leaving the drum full of water, the drain pump is a common cause. This genuine pump, part 146258, is also written 00146258 and cross references 00146193, 00145935, 00146117, 00146403 and 12044806. It's listed for the WAW28460AU and WAW28420AU, the WAP24160AU and the WGA254U0AU.

Bosch washing machine not draining or spinning

The drain pump empties the drum after each wash and rinse, and the machine won't move on to its spin until the water has gone. A pump that has failed electrically leaves the drum full and the cycle stuck, usually with a drain fault on the display. One with a jammed or broken impeller may hum while nothing drains, or rattle loudly as it runs. Coins, hairpins and bra wires are frequent culprits, so clean the pump filter at the bottom front of the machine before deciding the pump itself is gone.

Swapping the drain pump

Unplug the washer and turn off the tap. Drain the remaining water through the filter cap into a shallow tray, and expect more than you think.
