Bosch Classixx 1200 rattling noise during change from rinse to spin

The problem

A used Bosch Classixx 1200 washing machine makes a rattling noise from the front bottom right-hand area only when changing from rinse to spin. The noise stops once the spin is fully underway.

Likely cause

The accepted reply says the most likely cause is an obstruction inside the pump. A less certain possibility mentioned is that something became dislodged during transit.

What fixed it

Check the pump and pump filter for an obstruction and clean the filter if required. The discussion does not confirm the exact repair carried out or whether the noise was resolved afterwards.

Checks to try

• Observed that the noise comes from the front bottom right-hand area
• Noise occurs only when changing from rinse to spin
