Miele W916 internal filter keeps blocking

Calling out most manufacturers is now ridiculously expensive. Even many cheap washing machine manufacturers charge around the £90 mark. If a washing machine’s only cost £200 to buy this is totally unacceptable. Even with an expensive washing machine like a Miele its way too high although it's a much smaller percentage of a replacement cost.

I’d recommend trying to find an independent repair company or sole trader in your area although they are becoming increasingly rare. This link displays several appliance repairers on Whitegoodshelp - Find a washing machine repairer. Miele though are one of the makes that many independents don’t repair but it’s worth a look as they can be a lot cheaper than the manufacturer.

I’m not aware of any internal filter protecting the pump. Any coin should end up in the pump filter at the front where you can access it yourself. Have you seen where the engineer finds this filter? The only other place I can imagine one is inside the sump hose which leads to the water pump, but with a proper filter built into the machine at the front it should be unnecessary to have one in the sump hose as well. The problem is that most customers can't get to it, and with a built in filter specially for customers to clean already present - that's frustrating.
