Step 14

              Remove debris

In my case, the pump inlet (where we just removed the hose coming from the tumbler) was clogged with debris and some cloth.
This prevented draining, and even prevented removal of the filter. Thus, requiring disassembly. But we are not done yet.

Step 16

              Clean inlet, filter, and pump

At his point you can clean the water inlet, the filter, and the pump. The propellor should move freely. The pump itself can also be removed to replace it (but I did not do that).
In my case, a significant amount of cloth got stuck in the water inlet, including a necklace. In the filter, there were some hairpins, and inside the pump itself, a coin and a pendent. LESSON: CLEAN THE FILTER MORE OFTEN, while you can stil remove it without disassembling the machine.

Perfect! It helped me to disassemble this same model to find out that our pump was jammed with a thin thread. Had to replace the pump, but that was the easy part once the machine was disassembled!

Tony Baroona - Jul 5, 2022

Awesome guide, many thanks Tom. Took just over an hour to have it back up and running (cleaned our pump with underwire and a cotton ball). Hardest part was that clip on the right of the sensor panel. and getting the rubber seal back on. Many thanks again!

Fantastic. Amazing resource. Saved me so much time, money, hassle.

Found my fault, a simple disconnected pipe and re connected it.

Andy Mason - Jan 9, 2023

Thanks Tom, what an excellent guide, really appreciate the effort you’ve made in creating it.

All done in under an hour, I didn’t break anything and didn’t end up with any screws left at the end for a change.

The hoop and spring that holds the rubber around the door was the only bit that I struggled with as it’s a very, very strong spring.
